Foil 69 Determining and Testing Class of Object

From CPS616 Lectures on Java CPS616 Basic Information Track for Computational Science -- Winter-Spring Semester 96. by Geoffrey C. Fox * See also color IMAGE

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
