Break statement is one of the different control statements which we use very often. If break statement is found in loop, it will exit the loop and execute the statement following the loop.

When you run above program, you will get below output:
53 is present in the array
Executing statments following the loop
Executing statments following the loop
Labeled break statement:
Labeled break statement is used when you want to break labeled for loop.
For example:
You want to find an element in two-dimensional array. Once you got the element in the array, exit the outer loop.

When you run above program, you will get below output:
65 is present in the array
Executing statements following the outer loop
Executing statements following the outer loop
Switch Case:
You can also use break statement in switch case. Once case condition is met, you will exit the switch case.
For example:

package org.arpit.java2blog; public class SwitchCaseExample { public static void main(String[] args) { char vehType = 'C'; switch(vehType) { case 'B' : System.out.println("BUS"); break; case 'C' : System.out.println("Car"); break; case 'M' : System.out.println("Motor cycle"); default : System.out.println("Invalid vehicle type"); } System.out.println("Your vehicle type is " + vehType); } } |
When you run above program, you will get below output:
Car
Your vehicle type is C
Your vehicle type is C
