Determining the Called Class

Question

I have a Java program that is run in Command Line, that contains a set of classes that I have written which all contain common code elements.

Lets assume the structure is the following:

package.AbstractParent  (contains: static void main)
package.ClassA          (extends: AbstractParent)
package.ClassB          (extends: AbstractParent)

When I do the following: java package.ClassA, the static void main within the AbstractParent is called.

Without putting a static void main in ClassA and ClassB, is there a way that I can determine which was called within AbstractParent?

For example, when I run java package.ClassA, AbstractParent will determine ClassA. When I run java package.ClassB, AbstractParent will determine ClassB.

Found the answer fairly quick, but Googling was troublesome, so I'll leave this here.

In the end, I was able to use System.getProperty("sun.java.command") to resolve the class. However, it does contain all the subsequent arguments that are included:

className = System.getProperty("sun.java.command");
className = className.substring(0, className.indexOf(" "));

From either context, it returned either package.ClassA or package.ClassB
