You can't.
Number is an Object and immutable.
You can do things like:
Number n = new Integer ( tmpCode.intValue () + 1 );
or better:
int i = tmpCode.intValue ();
... calculate something...
i++; i--; i=i*i;
... calculated something...
tmpCode = new Integer ( i );
You should have a look into the java tutorials.
