How to use the break statement in java program?

[Madaleno]

Hello to all,
I am new to this forum. I recently started learning java language. In our last lecture we learned break statement. After that our sir asked us to write program using break statement, but none of us able to write that program. That's why I am asking this question on this forum. Can anyone tell me How to use the break statement in java program? Please help me.
Thank you.

There are two types of break statement,one is the unlabeled and other is labeled break. Following program is the example of unlabeled break. Just try to understand it.

package org.kodejava.example.lang;

public class BreakDemo {
    public static void main(String[] args) {
        int[] n1 = {8, 3, 9, 1, 9, 5, 4, 1, 9, 22};

        int index1;
        boolean found = false;

        int search1 = 7;
        for (index1 = 0; index1 < n1.length; index1++) {
            if (n1[index1] == search) {
                found = true;
                break;
            }
        }

        if (found) {
            System.out.println(search + " found at index " + index1);
        } else {
            System.out.println(search + " was not found.");
        }

    start:
        while (true) {
            for (int x = 0; x < 10; x++) {
                System.out.print("x = " + x + "; ");
                if (x == 5) {
                    System.out.println("");
                    break start;
                }
            }
        }
    }
}

Some times what happened that we have to exit from a loop before the completion of the normal loop and in this case we have to use break statement and exit from the loop and loop is terminated. The break statement is used in while loop, do - while loop, for loop and also used in the switch statement.

public class  Break{
  public static void main(String[] args){
    int i,j;
    System.out.println("Prime numbers between 1 to 50 : ");
    for (k = 1;k < 50;k++ ){
      for (l = 2;l < k;l++ ){
        if(k % l == 0)
        {
          break;
        }
      }
      if(k == l)
      {
        System.out.print("  " + k);
      }
    }
  }
}

Break statement is used to break flow of normal control and is used to transfer that control to another loop. Just try to understand following example. It is very easy program. Try to understand each step.

 

      public class JavaBreakExample {

 public static void main(String[] args) {

 int intArrays[] = new int[]{5,8,3,5,1};

System.out.println("Elements less than 3 are : ");

 for(int k=0; k < intArray.length ; k ++)

      {

      if(intArray[k] == 3)

      break;

      else
 
      System.out.println(intArray[k]);

      }

       

      }

      }

Break statement is the powerful feature of java language. It is used to exit from the current running loop. Break statement can be implement with two statements one is for loop and other loop statement. Just try to undersatnd following example.

public class JavaBreakStatementExample {

    public static void main(String[] args) {

        for(int k=0;k<=20;k++)
        {
            if(k==10)
            {
                break;
            }
            System.out.println("Break loop :"+k);
        }
    }
}
