switch

• Evaluates an integer expression in the switch statement.
• Transfers control to an appropriate case label.
• If no match is found, control is transferred to a default label.
• If there is no default label and no other match is found, the switch statement is skipped.
• A break statement is usually used at the end of each case. If a break is not used, control flow falls through to the next case.
• All case labels must be constant expressions.
• The value that you are switching on must be byte, short, char, or int.
• Example:

    switch (verbosity)
    {
       case BLATHERING:
          System.out.println("blah blah blah ... my name is ...");
       case NORMAL:
          System.out.println("What is your name?");
       case TERSE:
          System.out.println("Yo.");
          break;
       default:
          System.out.println("Hello.");
    }
