How to set Java path?

Temporary Java path setting

• Copy the path of bin folder by going to jdk/bin i.e. C:Program
  FilesJavajdk1.7.0_60bin. Here jdk1.7.0_60 (will vary according to jdk version).

• Open command prompt and write set path=C:Program FilesJavajdk1.7.0_60bin and then press enter.

• This method will work only one time. After closing cmd you
  have to repeat the same process again.

Permanent Java path setting

• Right click on Computer
  and then select Properties.
• Then goto Advanced
  tab and click on Environment Variables.
• Now click on new
  and then in variable name field write path and
  in value field write the path of bin folder i.e. C:Program FilesJavajdk1.7.0_60bin

• Click ok to save settings. You have done!
• This will permanently set the path and you can run programs
  whenever you want.

Check path setting was properly or not

• You can confirm whether the path setting was properly or
  not. Just open cmd again, write javac
  and press enter.

• If it will show details about the java compiler then it is ok.
• If it will show and
  error like ‘javac’ is not recognized as
  an internal or external command then you have done something wrong. Check
  the whole process again.
