break statement

• a for loop
  • a while loop
    • a do while loop
    • a switch - case block.
    • a specific loop marked with a label.

    break - syntax

    break;
    break <label> 

    
    
    
    
    
    

    break - Example

    
    public class Break {
    public static void main(String a[]){
    	for(int i=1; i<=5; i++){
    		System.out.print("\nloop count "
    							+ i + ": ");
    		for(int j=1; j<=5; j++){
    			if(j>i){
    				break;
    			}
    			System.out.print( ""+ j + " ");
    		}
    	}
    }
    }
    

    The above code would print

    loop count 1: 1
    loop count 2: 1 2
    loop count 3: 1 2 3
    loop count 4: 1 2 3 4
    loop count 5: 1 2 3 4 5

    
    Example 2:

    
    public class BreakLabel {
    public static void main(String a[]){
    outer:
    for(int i=1; i<=5; i++){
    	System.out.print("\nloop count "
    						+ i + ":");
    	for(int j=1; j<=5; j++){
    		if(i==3){
    			break outer;
    		}
    		System.out.print(""+ j + " ");
    	}
    }
    
    System.out.println();
    
    for(int i=1; i<=5; i++){
    	System.out.print("\nloop count "
    						+ i + ":");
    	inner2:
    	for(int j=1; j<=5; j++){
    		if(i==3){
    			System.out.println(
    				"\nCalling break inner2...");
    			break inner2;
    		}
    		System.out.print(""+ j + " ");
    	}
    }
    
    }
    }

    This would print

    loop count 1:1 2 3 4 5
    loop count 2:1 2 3 4 5
    loop count 3:
    
    loop count 1:1 2 3 4 5
    loop count 2:1 2 3 4 5
    loop count 3:
    Calling break inner2...
    
    loop count 4:1 2 3 4 5
    loop count 5:1 2 3 4 5
    

    In the above example, 'outer' is the label. break outer is to break out of the for loop having the label 'outer'.
