You need to add the JDK directory to your path variable (and not your JRE path, as you do). JDK is usually located in:

C:\Program Files\Java\jdk1.6.0_xx\bin\

Where xxis the update number that you installed. Then just compile HelloWorld using:

C:\Your\dir\where\HelloWorld\Is\>javac HelloWorld.java

JDK, JRE, . JDK , Java Development ( ).

You can try writing cd C:\examples\ch01\ATM, then press "Enter" and this will change your directory. This allows you to write, for example java ATMCaseStudy, and then press enter. This should work if you put your C directory with the JDK in the same place.
