Since you can't overload operators in Java, you are left with these
kinds of solutions:

 MyClass m = m1.add(m2);

or:

 MyClass m = MyClass.add(m1,m2);

/gordon

You can do it via the constructor, but that implies that every operation
automatically creates new objects and it ties up the constructor logic doing
an implicit operation.  A cleaner and simpler solution is to do

MyClass temp = new MyClass ();
temp.set (m1);
temp.add (m2);

This means you only create new objects when you want to preserve the
original parameters.  I prefer this technique for long chains of operations
and it leaves you open to create all new kinds of operations. (Matrix /
Complex math is often done this way.)  You can combine the constructor and
set with something like

MyClass temp = new MyClass (m1);
or
MyClass temp = m1.copy ();

But the effect is largely the same.
