Branching statement: break

The break Statement

We already seen the use of break in switch case. Similarly, break is used in while, do-while and for loops. Break has two forms in java.

   1. unlabelled break

   2. labelled break

unlabelled break

   Example

class BreakEx{
 public static void main(String args[]){
  for(int i=0; i < 10; i++){
   if(i==5) break;
   System.out.println(i);
  }
  System.out.println("I am out of the loop");
 }
}

Output

0
1
2
3
4
I am out of the loop

 

As you in the above program, when variable “i” reached to 5, break is called, and execution comes out of the loop

labelled break

   label is a group of statements, identified by using labelname.

Syntax

    labelName:{

      statement 1

      statement 2

      …....

      statement N

    }

Example

class BreakEx{
 public static void main(String args[]){
  myLoop: {
   for(int i=0; i < 10; i++){
    if(i==5) break myLoop;
    System.out.println(i);
   }
   System.out.println("I am also in label");
  }
  System.out.println("I am out of the loop"); 
 }
}

        

Output

0
1 
2
3
4 
I am out of the loop

 

As you see in the above program label name is myLoop. When variable 'i' value reaches to 5,  execution comes out of the label.
