If you have java installed, the environment variable PATH is not set to locate java installed directory.



The actual solution is to set the PATH



The workaround is as below:



Suppose, your java installed directory path is: c:\java



to compile file

----------------------

c:\java\bin\javac MyPrg.java



to run

--------

c:\java\bin\java MyPrg

Answer 2

You need to set the path variable to where the java is installed in your system. Have a look at this page to help you out.

Now, you may need to know where you java is to be able to set the path.

Answer 3

If Java is installed on your computer, your computer does not know where it is located. Either that, or your should install it. If it's already installed, you don't have the environment set properly to point to it. I recommend re-installing it.
