How to Check Java_Home in Windows

Java is a programming language from Oracle Corporation which lets developers create cross-platform applications. The Java Development Kit requires its users to register and set a specific variable, JAVA_HOME, when developing applications on Windows. Checking if you have previously created the JAVA_HOME variable in Windows and if its syntax is correct allows you to use the Java Development Kit to develop Java applications. You can check if the JAVA_HOME variable exists on your system in just a few steps.

Instructions

1. Click on "Start" and right-click on "Computer." Select "Properties."

2. Click on the "Advanced System Settings" link in the left-hand pane to open the "System Properties" dialog box.

3. Select the "Advanced" tab and click on the "Environment Variables" button.

4. Scroll down the list of items under "System Variables." If "JAVA_HOME" appears in the list, click on it and select "Edit" to check its value and syntax. If it doesn't appear in the list, the variable is not currently registered on your system.
