How to use the continue statement in java program?

[Luz]

Hello to all,
I am second year B.Sc.I.T. student. I recently started learning java language. In our last lecture we learned concept about continue statement. Our sir told all of us to write java program using continue statement. I tried various method but I unable to write correct program. Can anyone tell me How to use the continue statement in java program?
Thank you.

The continue statement has 2 types of forms, one is unlabeled and other is labeled continue statement. The first example of following program you will see how to use the unlabeled continue statement. In the second example you will see how to use the labeled continue statement in java prgram.

package org.kodejava.example.lang;

public class ContinueDemo {
    public static void main(String[] args) {
        int[] numberss = {5, 11, 3, 9, 12, 15, 4, 7, 6, 17};
        int lengths = numberss.length;
        int counters = 0;

        for (int k = 0; k < length; k++) {            
            
            if (numbers[k] >= 10) {
                continue;
            }

            counters++;
        }

        System.out.println("Found " + countes + " numbers less than 10.");

        int[][] datas = {
                {8, 2, 1}, 
                {3, 3}, 
                {3, 4, 5}, 
                {5, 4}, 
                {6, 5, 2}};
        int totals = 0;

    outer:
        for (int k = 0; l < data.length; k++) {
            for (int l = 0; l < data[k].length; l++) {
                if (data[k][l] % 2 == 0) {
                    continue outer;
                }

                totals += data[k][l];
            }
        }

        System.out.println("Total = " + totals);
    }
}

Sometimes what happened that we don't need to execute some statements under the loop statement and in this case we use the continue statement. It stops normal flow of the control and helps in transferring control to the loop without executing the statements written after the continue statement. I had written following example which has continue statement. Try to understand it.

public class Continue{
  public static void main(String[] args){
    Thread q = new Thread();
    int aw = 0;
    try{
      for (int k=1;k<10;k++)
      {
        if (k == 5)
        {
          continue;
          
        }
        q.sleep(1120);
        System.out.println("varun");
        System.out.println("Value of w : " + w);
      }
    }
    catch(InterruptedException e){}
  }
}

Using following program you will understand continue statement. First you have to define class "Continue". This program take input fro user and display it on computer screen. Try to understand how continue statement is used in following program. Continue statement is used to transfer control to other code.

import java.io.*;

class Continue{
  public static void main(String[] args) throws Exception{
    int p=2;
    BufferedReader object1= new BufferedReader(new InputStreamReader(System.in));
    System.out.println("Enter your desired number");
    int s= Integer.parseInt(object.readLine());
    for (int k=0; k<=4; k++){
      if(k==2){
        continue;
      }
      System.out.println("value of p ="+ p);
    }
  }

The continue statement is used to transfer normal flow control to other condition. It is used to break normal flow control. You can use Continue statement anywhere in the program. Just make sure that it must be at the end of any loop and after that there should have another loop condition. Just try to understand following program.

class ContinueDemo {
    public static void main(String[] args) {

        String searchMe = "Welcome o the party";
        int maxx = searchMe.length();
        int n1 = 0;

        for (int k = 0; k < maxx; k++) {
            
            if (searchMe.charAt(k) != 'komal')
                continue;

       
            n1++;
        }
        System.out.println("Found " + n1 + " komal's in the string.");
    }
}
