Java break keyword example

In Java, the break keyword stops execution of for loop, while loop and switch-case construct. The execution goes to next statement after the construct is broken.

The following example shows a break statement inside a for loop:

for (int count = 0; count < 100; count++) {
    System.out.println("count = " + count);
    if (count > 70) {
        break;
    }
}

The above for loop prints values of count from 0 to 70.

The following example shows break statement is used in a while loop:

int number = 0;
while (true) {
    number++;
    System.out.println("number = " + number);
    if (number > 1000) {
        break;
    }
}

The above while loop will stop when the value of number is greater than 1000.

The following example shows break statements are used in every case of the switch statement:

int monthNumber = 2;
String monthName = "";
switch(monthNumber) {
    case 1:
        monthName = "January";
        break;
    case 2:
        monthName = "February";
        break;
    case 3:
        monthName = "March";
        break;
    case 4:
        monthName = "April";
        break;
}
System.out.println("The month is " + monthName);

The above code will produce the output: The month is February. The break statements prevent the execution from falling through from one case to another.
