1.) A Class
A "class" is the same as a function, sub routine, sub program. A way to break up a program into small easier manageable parts. Also a class is the name of the file. for example
Would be saved as MyCalss.java and compiled as MyClass.class
2.) A Method
The processing portion. What I am thinking is, the action, the part od the code that dose something. You can have many methods in a class.
An example would be
public void myMethodThatReturnsNothing()
{
}
