The Class is what you type out in your code editor. In a class you can choose what data structures (primative variable types, object references, methods) the objects created from that class will have. When you run your program a class can be put into memory as one or more Objects.

An Object is, well, its own, self-contained object in memory with the internal structure of the class it is based on.

An Object is created with the new keyword and a matching constructor. Example, I create a new Object reference using Object's no argument constructor (see the constructor of ther Object class of Java ME API):

Object o = new Object();

Here, the new Object has the named reference "o" which I can use to call methods inside that object, example:

o.toString()

A Subroutine, as you call it, is called a method in Java. A Method is where you put lines of code, when you write a class, that are suppose to run when you call that method.
