A few years ago, most software programs used the operating system of the device on which they were loaded as the runtime environment. It also provides the latter with access to system memory and resources, without which the application wouldn’t work. What is a runtime environment?Ī runtime environment consists of a set of class files needed by a software program to run. Java Runtime isn’t limited to Windows and is also available for download on Mac devices. Without it, you may have trouble loading games, chat boxes, and movies. Since numerous web applications rely on JRE to function, you should have the latest version installed on your Windows device. It’s an essential component of the Java Development Kit (JDK) and contains all the tools needed to run different Java-based software programs. Java Runtime Environment (JRE) is a software layer that provides services required to execute Java applications. So when you want to change the JDK you change only the JAVA_HOME variable and leave PATH as it is.Xavier Slim Updated 9 months ago Run different Java applications Note: You can also point JAVA_HOME to the folder of your JDK installations and then set the PATH variable to %JAVA_HOME%\bin.
If you want to uninstall - just undo the above steps. To see if it worked, open up the Command Prompt and type java -version and see if it prints your newly installed JDK.
Enter the variable value as the installation path of the JDK (without the bin sub-folder).
The following is a typical value for the PATH variable: C:\WINDOWS\system32 C:\WINDOWS "C:\Program Files\Java\jdk-11\bin".Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.Click Advanced and then Environment Variables.You may need Administrator privileges to extract the zip file to this location. C:\Program Files\Java\ and it will create a jdk-11 folder (where the bin folder is a direct sub-folder).
