The path is required to be set for using tools such as javac, java etc.
If you are saving the java source file inside the jdk/bin directory, path is not required to be set because all the tools will be available in the current directory.
But If you are having your java file outside the jdk/bin folder, it is necessary to set path of JDK.
There are 2 ways to set java path:
To set the temporary path of JDK, you need to follow following steps:
set path=C:\Program Files\Java\jdk1.6.0_23\bin
Let’s see it in the figure given below:
