How to run a java program

[Mohnish Khiani]

whenever i have to run a java program in the command prompt i have to set the current directory to the bin folder inside the java folder's jdk folder.i also have to save my programs in the bin folder to run them.What should i do if i have to save my programs somewhere other than the bin folder in the java folder and also run these programs from command prompt.

It is usually a very bad idea to save your own work inside the bin folder. When you open the command line try this (or similar)

mkdir java_work
cd java_work

Don't save anything in bin.
The next time you will only need

cd java_work

. . . and look at this FAQ.

You have to add the bin directory of the JDK to the PATH environment variable. You can read how to do that in the JDK installation instructions, step 4 (Update the PATH variable). Note that you have to close and re-open the command prompt window after changing the variable.
