toString

•Suppose

SomeClass foo = new SomeClass( )

•Then these two expressions do the same thing:

System.out.println( foo.toString() );

System.out.println( foo );

•Every object knows how to respond to a toString message since there’s a toString in class Object

•For “foo” etymology, see the full online dictionary of computer science at http://foldoc.doc.ic.ac.uk
