Java is a very popular programming language and is gaining a lot of attention by the budding Android programmers. Java beginner’s programming tutorial requires you to download the Java JDK software bundle, followed by writing the source code of the ‘HelloWorld’ program in Notepad and compiling it in a terminal window.


But most users face problem in the compiling step and it gives an error – ‘Javac is not recognized as an internal or external command, operable program or batch file‘.

2. Click on the ‘Environment Variables‘ button.

3. Under the System Variables, go to ‘Path variable‘ and press Edit.

4. Find the location of the ‘Javac‘ file using Windows Explorer search and copy the path.

E.g. C:\Program Files\Java\jdk1.6.0_24\bin

5. In the Variable Value section, paste the location of the Javac file in the beginning of all values followed by a semicolon (;), without erasing the previous values.

E.g. C:\Program Files\Java\jdk1.6.0_24\bin;
