To Find Java Path in Linux

Here are the steps to find Java Path in Linux System –

Step 1: Open a Terminal window.

Step 2: Type the following command and press Enter:

which java

Step 3: You should see the path to your Java installation printed on the terminal. It will typically look something like this:

/usr/bin/java

That’s it! You’ve found your Java path in Linux.

PATH is an environment variable that is used by Operating System to locate the exe files (.exe) or java binaries ( java or javac command). The path once it is set, cannot be overridden. The PATH variable prevents us from having to write out the entire path to a program on the Command Line Interface every time we run it. Moreover, the path is just a variable that stores a bunch of shortcuts.

To execute Java console-based programs in Windows or Linux environments, we have to use Java and javac commands. The commands java and javac are not known to the operating system as we don’t specify where the executables reside. Hence, we need to specify the path where the executables are located. This is the reason we set the path and specify the path of the bin folder because the bin contains all binary executable files. After setting the path, it can load all necessary items in the program including the compiler or interpreter itself. 

Below is the procedure for how to set Java Path in both Windows and Linux?
