Java Runtime Environment - minimal Java for Windows. Basic troubleshooting tips for using Java.

In the process of performing tasks on a computer or laptop, Java is sometimes required. One of the most common reasons is the correct operation of the browser - each of them can use their own copy of the program, so checking the Java version may be required.

What is Java and why is it needed?

Before understanding how Java validation works, it's helpful to understand what the program is and what it does. Thanks to the use of this program, a special technology is implemented that allows you to increase the level of reliability of the device, as well as the speed of operation. Currently, there are many programs that require Java, as well as websites for correct operation which require a version not lower than a certain one.

Checking the Java version is very simple, and regardless of the type of operating system, it can be done in two ways - online or offline.

Website verification

The Java technology company, in addition to releasing regular updates, has added the ability to check the installed version of the program to its official website. In order to get to the page where the Java version is checked, you need to use the search on the site, or a direct link.

This portal contains a button that prompts you to launch an application that will determine the version of the program. After agreeing to run in the pop-up browser security window, after a few seconds, the result of the request will be displayed on the page, in which the version and update number will be written in brackets.

Offline check

Without being able to access the Web, you can use the offline method. On Windows check Java versions are carried out through the command line - it can be launched by finding the "Start" menu - "All Programs" - "Accessories", or using the "Run" item, where to write the line cmd.

In the window that opens, you only need to enter the following command: java-version. A query may result in several different messages. If you have one of the latest versions of the program, command line will display a list of installed instances, each with its version. If installed program is not present on the computer, or one of the first versions is used, an error message will be displayed.

In order to find out the Java version on MacOS and Linux operating systems, you need to use the terminal, where you will have to enter a similar line. The result of the query will be the same as on Windows.

Some programs, not only web-based applications, but also full-fledged desktop programs, require a virtual machine for their work. JAVA, which must be installed on your computer. Apart from virtual machine The program may need other modules.

Important for the performance of programs, and in particular the newest ones, is version installed on your computer.
