Exiting a Loop

The normal way to exit a loop is for the condition that is tested to become false. This is true of all three types of loops in Java: for, while, and do-while. However, there might be times when you want a loop to end immediately, even if the condition being tested is still true. You can do this with a break statement, as shown in the following code:

int index = 0;
while (index <= 1000) {
    index = index + 5;
    if (index == 400)
        break;
    System.out.println("The index is " + index);
}

The condition tested in the while loop sets it up to loop until the value of the index variable is greater than 1,000. However, a special case causes the loop to end earlier than that: If index equals 400, the break statement is executed, ending the loop ...
