Multiple Selections via switch

Note the “optional” default case at the end of the switch statement.

It is optional only in terms of syntax.

switch (iNumber) {

case 1:

System.out.println (“One”);

break;

case 2:

System.out.println (“Two”);

break;

case 3:

System.out.println (“Three”);

break;

default:

System.out.println(“Not 1, 2, or 3”);

} // switch

In practice you should always include a ‘default’

case statement.

E.g., 1989 AT&T phone system crash

This would

work without

the default, but

would be

poor

technique
