From Feb 3 Delivered Lecture for Course CPS616 -- Java Lecture 4 -- AWT Through I/O CPS616 spring 1997 -- Feb 3 1997. by Nancy McCracken * See also color IMAGE

Secs 20.1

Suppose an object is called obj , then we get Class of obj by

Class itsclass = obj.getClass(); // and the name of this class by:

String name = itsclass.getName();

One can also use instanceof in following fashion

"foo" instanceof String // is evaluated to true but

mPoint pt = new mPoint(x,y);

pt instanceof String // is evaluated to false
