If you are using Windows, then on the command prompt, type the following
c:\> echo %JAVA_HOME%
The output of this command will be the path where your JDK is installed.
For example:
C:\>echo %JAVA_HOME%
C:\Program Files\Java\jdk1.6.0_13\
C:\>

There will be a directory called "bin" in "C:\Program
Files\Java\jdk1.6.0_13\" (for example) which contains all binary files.
There will a java compiler file called "javac" present in the above
mentioned path.

Compiling javacode:
On the command prompt, type the following:
C:\> javac Hello.java

Once the java code is compiled without any errors, you can execute using the
following command:
 C:\> java Hello

Hope this helps
