Answer 1

Here is what finally worked.

`@echo off
set path=%path%;C:\Program Files\Java\jdk1.7.0_71\bin;
set classpath=C:\Program Files\Java\jdk1.7.0_71\lib;
cd 
javac .\trainingPackage\HelloWorld.java
cd ..
java trainingPackage.HelloWorld 
REM (Make sure you are on the parent directory of the PackageName and not inside the    Packagedirectory when executing java).`
