Another very unique flow-control statement used to select code to execute is the switch-case.  The switch-case is used when the value of one integer or character is used to decide which code to execute.  An example:
int choice;
System.out.print("What is your choice (1, 2, or 3)? ");
choice = Stdin.readInt();
switch(choice) {
    case 1:   System.out.println("You said one.");
              break;
    case 2:   System.out.println("You said two.");
              break;
    case 3:   System.out.println("You said three.");
              System.out.println("Aren't you cool?");
              break;
    default:  System.out.println("That's not a choice."); }

    When this code is executed, the value of choice will be compared to the numbers that appear by the word case.  The list will be searched from beginning to end, until a matching number is found.  Once a match is found, all of the code after the colon will be executed until a break statement is hit.  The numbers by the case's must be int literals or char literals.  If no match is found, the code after the word default will be executed.  The default section is optional.  If it is not there, nothing in the switch-case will be executed when no match is found.  Since the comparisons are done to literals, the switch-case is not a good choice when you want to compare to a range.  Since the code in a switch-case will continue executing until a break statement or the end of the switch-case is reached, execution can continue from one case to the next if there is no break statement.  This is called fall-through, and it can be useful:
int choice;
System.out.print("What is your choice (1, 2, or 3)? ");
choice = Stdin.readInt();
switch(choice) {
    case 1:   System.out.print("One little...");
    case 2:   System.out.print("Two little...");
    case 3:   System.out.print("Three little...");
    default:  System.out.println("Java programs."); }
but the vast majority of the time fall-through happens in a switch-case, it's the result of a mistake.
