Setting Path For Java Programs

You can run Java applications just fine without setting the PATH environment variable. Or, you can optionally set it as a convenience.
Set the PATH environment variable if you want to be able to conveniently run the executables (javac.exe, java.exe, javadoc.exe, and so on) from any directory without having to type the full path of the command. If you do not set the PATH variable, you need to specify the full path to the executable every time you run it, such as:

C:\Java\jdk\bin\javac program.java

The Method:

Open Notepad,Write The Following Code.

PATH=C:/java/jdk/bin

Save it as setpath.bat
Now,You Can Run The Program Without Navigating to Directory.
There is only disadvantage in this Method.You have to Run setpath.bat each time you Restart your Computer.
There is Another Method For Setting Class Path Permanently.
It Can be Found on Official Oracle Site Here.
