An Environment variable is a dynamic "object" on a computer that stores a value(like a key-value pair), which can be referenced by one or more software programs in Windows. Like for Java, we will set an environment variable with name "java" and its value will be the path of the /bin directory present in Java directory. So whenever a program will require Java environment, it will look for the java environment variable which will give it the path to the execution directory.
Assuming that you have installed Java in C:\ Program files/ Java / JDK directory
Step 1: Right click on my computer and select properties.
Step 2: Go to the Advance System Settings tab.
Step 3: Click on Environment Variables button.
Step 4: Now alter the path variable so that it also contains the path to JDK installed directory.
For e.g:- Change C:\windows/ system 32. to C:\windows/system 32; C:\program files / Java/ JDK.
Assuming that you have installed Java in C:\program files\ java\ JDK directory, do the following:
Step 1: Edit the C:\autoexec.bat file and add the following line at the end.
SET PATH =% PATH% C:\ PROGRAM FILE/JAVA/JDK/bin
Step 1: Environment variable path should be set to point where java binaries have been installed. Refer to your shell if you have trouble doing this.
For Example: If you use bash as your shell, then you would add following line to the end
bash mc: export PATH=/ Path/to/java
