Figure 11-2 Action of a Labeled Break

The following program shows the use of a labeled break to implement
an error handler.

// File name: LabeledBreak.java

// Reference: Chapter 11

//
// Java program to demonstrate direct flow control

// Topics:

// 1. Action of the labeled break statement

// 2. Use of a labeled break in an error handler

//
// Requires:

// 1. Keyin class in the current directory

public class LabeledBreak
{

public static void main(String[] args)
{
int number = 1;
char letter;

letter = Keyin.inChar("Enter any character, except C: " );

FAST_EXIT:
while(number < 10 )
{
System.out.println("number is: " + number);
number ++;
for (char ch = 'A'; ch < 'D'; ch++)
{

System.out.println(" char is: " + ch);
if (letter == 'C' || letter == 'c')
break FAST_EXIT;

}
