Setting up Environment in Java

Step 1:

Locate the JDK Installation Folder:

After installing the JDK, finding out where it’s installed is important. By default, java is installed in the “C:\Program Files\Java\jdk\bin” folder OR “C:\Program Files(x86)\Java\jdk\bin”. In case, you have installed Java at any other location, then add that path.

C-drive  🡪 Program Files🡪java 🡪 jdk 🡪 bin (copy the path)

Step 4:

You will see a list of different paths, click on the New button, and then add the path where java is installed. By default, java is installed in “C:\Program Files\Java\jdk\bin” folder OR “C:\Program Files(x86)\Java\jdk\bin”. In case, you have installed java at any other location, then add that path.

Step 5: 

Click on OK, Save the settings, and you are done !! Now to check whether the installation is done correctly, open the command prompt and type java –version. You will see that Java is running on your machine.
