Many users encounter a Java program on their computers and a completely logical question arises - what kind of program is this and what is it for?

Java is a technology that is used to develop online applications, that is, programs that launch and run directly in your browser.

Such applications significantly expand the capabilities of the Internet and with the help of Java technology we can play online games, communicate in various online chats, upload photos and videos to various sites, and much, much more.

But in order to take advantage of all these benefits, you must have Java installed on your computer. That is, this special program, allowing you to run Java content directly in your browser. If the environment is not installed on your computer, then many online applications and websites simply will not work. Usually in this case, when you visit a web page containing Java content, a message appears asking you to download and install Java on your computer. Many people do this without even thinking, and then questions arise like: “what kind of program is this?”, “how did it get on my computer?” and “what is it for?”

Also, after installation on your computer, Java will monitor the appearance of new updates on the official website and as soon as they appear, you will receive a message asking you to install them.

Since Java applications are very popular and are used everywhere on the Internet, attackers can use them for their own purposes. This means that you should always update Java on your computer, as updates fix discovered vulnerabilities and improve security and stability.

Why do you need Java on a computer or laptop?

If you see Java in the list installed programs, but don’t know why it is needed - this article is for you. Many users ask why Java is needed on a computer or laptop, how it was installed, and what it does. Let's figure it out.

Why is Java needed?

Java is a free platform that is designed to run applications written in the Java programming language of the same name. Many programs and web applications run in Java. What is this platform?

The JRE - Java Runtime Environment - is most often installed on the computers of ordinary users. Roughly speaking, this is a container within which Java programs are launched and run. It provides security, stability and environment for some of the software on your computer.

Previously, Java was actively used to write “applets” - small applications that run directly in the browser. For example, a calendar, guest book or online chat. Currently, JavaScript is used for these purposes, which does not require Java installed. But still, many sites on the bottomless Internet operate on this technology. And if you don't have Java, then such sites will not work correctly and you will not be able to interact with them. The site does not respond to your actions? Perhaps the reason lies in the lack of Java.

More widely, Java was and is used to create desktop applications. Therefore, some programs simply cannot work without Java installed. For example, popular game Minecraft runs exclusively inside a Java virtual machine. And if you are involved in programming, then some IDEs (software development environments) also require Java to run.

Where does Java come from on my computer?

Java is often installed immediately after Windows installations or another OS as a utility program. It may have been installed by the person who installed Windows for you, or it may have come pre-installed on your PC or laptop. Or some application that requires Java has installed it on the PC. Just know that this is not a malicious application at all, and there is no need to remove it while cleaning your computer. It’s not for nothing that we included Java in the list of necessary programs for Windows.

From time to time, you may see notifications asking you to update Java. With each update, the Java platform is improved, vulnerabilities are addressed, and bugs are fixed. I recommend agreeing and updating it. This also applies to other software - periodically update your antiviruses, the programs you use, and your operating system. Now you know why you need Java on a PC and what it does.

How and why do you need to install Java on your computer?

Until recently, the Java architecture was known only to advanced users and developers, but today a lot has changed. As it turns out, many programs are currently written in this free programming language, which provides good prospects for their development. In particular, it contains the name of a client of the famous Minecraft games, and therefore many users began to be interested in how to install Java on a computer. If you are also interested, we invite you to read this article.

However, before talking about the installation process, one cannot help but pay a little attention to the technology itself. Java is a programming environment and computing environment developed and maintained by Sun Microsystems Corporation. Its peculiarity is that this environment is cross-platform and is used in many mobile devices and even in spacecraft. In short, if you work in some application that uses this technology (and you almost certainly do), then you should definitely install Java on your computer.

Why do you need to install Java?

Considering the prevalence, cross-platform and complete openness of the code, one should not be surprised at the huge number of sites and applications that will not work without this technology. If you do not install Java on your computer, then all this wealth may either refuse to function at all, or will begin to work not entirely correctly. By the way, it is Java that underlies the much-loved Android mobile OS, whose market share continues to increase at an accelerated pace.

We install the application

Before you install Java on your computer, you need to check whether it has more than old version. To do this, you will need to run an application on your computer to emulate the mode command line. If you are a beginner, then click on the “Start” button, look for the item called “Run” there, and then enter “CMD” (without quotes) in the command field. Press Enter or the OK button.

After this, a command line window will appear in front of you, in which the cursor will blink on a black background. Copy (without quotes) and paste the Java-version command into it using the Copy-Paste command and the mouse (the Ctrl+V keyboard shortcut does not work). After this you can press Enter.

If you already have this program on your computer, then in the first line you will see something like: “Java-version 1.5.0”. If you see a message like this, you don’t have to install anything. Otherwise, you must continue with the installation.

But! The previous operation requires us to launch the command line in administrator mode, and in the way described above it most often starts from a simple user. This doesn't suit us. To be sure to run the utility with administrator privileges, you need to do things a little differently.

To do this, click on the “Start” button again, look for the “Search programs and files” field there, enter CMD there, then in the window that appears with the search results, find (as a rule, only this line will be there) the file of the same name. Right-click on it and select “Run as administrator” from the context menu. All! It's time to install the Java program on your computer.

After downloading the installation file, double-click on it with the left mouse button. The “Installation Wizard” window will appear, in which you need to click on the Install button, after which the installation process will begin. Depending on the power of your PC and Internet capabilities, it may take different time. Finally, click on the Close button.

So you have learned how to install Java correctly!

About java technology, what it is needed for and where to download new versions

Java technology allows web applications and applets to run in a secure isolated environment on a Java virtual machine on any operating system on any device. Due to its versatility and applicability in any field from super computers, cars to cell phones, Java has become so widespread and popular among developers. Users do not notice it, but use it every day on their computer, laptop, both simple and the most advanced, cell phone for surfing the Internet, playing games and reading books. Why is it necessary to update the Java package? The fact is that virus and malware developers are not asleep and strive to use Java vulnerabilities for their own purposes, because it is through scripts using exploits in Java that it is easiest to inject malicious code onto a user’s machine through a browser from special Internet resources. Therefore, updating the Java package is mandatory for those users who are concerned about the security of their own information, the overall performance and stability of their computer or laptop.

After such a description, which I hope is understandable, I would like to believe that ordinary computer users will not have the question “What is Java for?”

And now main question- “Where can I download new versions of Java?” To download and subsequently install, you must follow the links below and select the green button in the upper right corner - Download Latest Version. After this, downloading and installing the Java platform on your computer or laptop will not be difficult. Just follow the installation wizard.

I further recommend watching the video. Those who know English and are a little involved in IT will like it. Subtle humor about Java and the .NET platform from Microsoft. Java at its best! On the other hand, Microsoft has Windows 7, operating system, which can be installed in Moscow, and Oracle, in addition to Java, has OpenOffice.org (or it was), MySQL, Virtual Box (with which you can try the new Windows 8 without reinstalling the current system), Solaris and much more. So, they are worthy opponents, we wish them good luck! Thus, we figured out general outline, what Java is needed for and where to download new versions. Everything is obvious and simple. After all, system administrators often have situations that are much more complicated, where it is difficult to find a simple solution (this is a joke).

Why do you need java?

Who knows why java is needed? Has it ever happened to you, while wandering around the Internet, to come across names such as JavaScript, Java GUI & Java FX, etc. An ordinary user will never understand what it is. Let's try to figure out why java is needed?

Java This special language programming in which video games and various applications are usually written. So, for example, if your phone has support for java applications, this means that you can run and use various programs written in java on it: games, calendars, clocks, area maps, currency converters, etc. This the language is also used in the field of Web technologies. It is probably now partly clear to you why you need java?

If we consider its application in the field of Web technologies, then to the average user The PC will understand if we say that java is used by the Internet browser to correctly display loaded pages. It allows you to use the active content of pages of various sites. It is with its help that some programs are launched.

In order to become more familiar with this program language and understand why java is needed, you can independently refer to various kinds of reference literature.

Why do you need a Java program on your computer?

A technician came to me to set up my computer. I installed Windows 7, a bunch of drivers and a dozen standard programs, obviously. So I look at the list of programs, and I seem to understand everything why they are needed. But I don’t know why I need a Java program on my computer. Is it something systemic, like a driver? Thanks for the answer.

There are many applications and websites that do not work without Java installed.

Java is such a programming language (object-oriented, if that says anything). The beauty of it is that Java applications can run on any platform and computer architecture with the help of a so-called Java virtual machine. Actually, when you download Java, you download this particular virtual machine to your computer, which can interpret the code.

Without installing this distribution, many of the programs, for example, OpenOffice, Minecraft, etc., simply will not work. Even the nVidia driver wrapper uses it. Therefore, it is necessary to install it.

Java is a special language for writing programs. For these programs to work, you need to install Java on your computer (one for all Java programs).

This distribution can be installed on a system, which is better (less hassle) and portable. There are programs in almost every category in Java. If I'm not mistaken, they can work on a computer with any OS (not just Windows). And even on mobile devices.

Hello everyone Let's talk about what Java Update Scheduler is, what kind of program is it? Well, the first and probably most important thing is that this is not a virus, that’s already good! This is a Java component that sometimes, from time to time, checks for a new version of Java. If there is a new version, then most likely you will be given a message saying that there is a new version of Java and you need to download it. Or it may be that it will be installed automatically, some programs are updated this way, for example Google Chrome

This thing, Java Update Scheduler, runs under a process called jusched.exe, so if you see it in the manager, you will already know what it is. Yes, you can disable it in the same manager, but this is NOT a solution to the problem, because it will most likely appear again later.

It’s strange, of course, but I don’t have the jusched.exe process in the manager. I don’t even know why, maybe it’s in older versions of Java? Or maybe they complained about it a lot and decided to remove it? Well, I don’t know how it really is, but I don’t have it, period.

But there are other processes, these are javaw.exe, jp2launcher.exe, jucheck.exe, well, look for yourself:

Yes, there are quite a few Java processes, and one of them definitely checks for updates, so to speak, checks them, this is jucheck.exe. But then it’s not clear why jusched.exe is needed?

I looked for the jusched.exe file on the disk and finally found it, it is located in the Java Update folder, which means it definitely belongs to the update:

C:\Program Files (x86)\Common Files\Java\Java Update

I right-clicked on the file and selected Properties there, look, it also says that this is Java Update Scheduler:

But as you can see, there is the word Scheduler, which means that perhaps this has something to do with the scheduler, maybe this process creates a task in the scheduler regarding the Java update?

So, what is the solution to remove the jusched.exe process forever? You can simply delete the Java Update folder from here:

C:\Program Files (x86)\Common Files\Java

And then you will get rid of all sorts of things that relate to updating Java. Because it’s not so difficult to go to the official website and manually install new version Java, I think you agree with me.

You can also disable checking for updates; oddly enough, there is a setting for this. Press the Win + R buttons and write the following command there:

A window with icons will open, here you need to find the Java icon and click on it once:

A window with Java settings will appear, here you need to go to the Update tab and there uncheck the automatic update box, this checkbox is:

Click OK and all is well, automatic update You have disabled Java

In principle, this is enough. I personally delete the Java Update folder; I like this method better. And if anything, I myself can manually download a new version of Java and install it, it’s not difficult for me.

But you can simply disable the jusched.exe process, and do it safely, you never know, in case you don’t want to change the settings or delete the Java Update folder. Disabling is safe and you can return everything back at any time, there is no point in telling me how to do this, because I have already talked about this with an example
