How to set path in Java

JDK (Java Development Kit) is a software development environment which has collection of various tools and libraries to develop a Java program.

In order to run a Java program, you have to install JDK in you device. After the JDK installation, path has to be set properly, or else you cannot run the code.

Only if the Java file exists outside the jdk/bin folder, it is required to set the path of JDK. If the file is saved within the jdk/bin folder itself, there is no need to set the path.

To set the path in Java, you can use two ways:

  1. Temporary

  7. Set the path of User Variables to the jdk/bin folder with the name PATH.
  8. To set the path temporarily in Windows:
