"int" is an intrinsic datatype. "Integer" is a class. Since java does not
support operator overloading, I don't think that you'll be able to apply
the "++" directly.
You acutally have to do this:
Integer iobj = new Integer(5); // Set init value.
iobj = new Integer( iobj.intValue() + 1 ); // Incr. value.
Therefore, before you decide whether to use 'int' or 'Integer', you must
consider how you will use the value.
