Operating Systems locate executable files (.exe) and Java binaries using the environment variable PATH ( java or javac command).
We must utilize the java and javac commands to run console-based Java programmes in Windows or Linux environments.
The path does not need to be set if you save the Java source file in the JDK/bin directory because all the necessary tools will be present in the current directory.
However, you must set the JDK path if your Java file is located somewhere other than the JDK/bin folder.
There are two ways to set the path in Java:
1) To set the Temporary Path of JDK in Windows
To set the temporary path of JDK, you need to follow the following steps:
- Open the command prompt
- Copy the path of the JDK/bin directory
Paste in command prompt: set path= C:\Program Files\Java\jdk1.6.0_23\bin
1) To set the Permanent Path of JDK in Windows
For setting the permanent path of JDK, you need to follow these steps:
a) Go to My Computer properties and Click on the advanced tab
b) Click on environment variables and click on new tab of user variables
Write the set path in java in the variable name and paste path of bin folder in the variable value
C:\Program Files\Java\jdk1.6.0_23\bin
Click on OK button
