Java - continue statement


The continue keyword can be used in any of the loop control structures. It causes the loop to immediately jump to the next iteration of the loop.

  • In a for loop, the continue keyword causes control to immediately jump to the update statement.

  • In a while loop or do/while loop, control immediately jumps to the Boolean expression.

Syntax

The syntax of a continue is a single statement inside any loop −

continue;

Java Continue Statement

Example 1

In this example, we're showing the use of a continue statement to skip an element 15 in a while loop which is used to print element from 10 to 19. Here we've initialized an int variable x with a value of 10. Then in while loop, we're checking x as less than 20 and within while loop, we're printing the value of x and incrementing the value of x by 1. While loop will run until x becomes 15. Once x is 15, continue statement will jump the while loop while skipping the execution of the body and loop continues.

public class Test {

   public static void main(String args[]) {
      int x = 10;

      while( x < 20 ) {
         x++;
         if(x == 15){
            continue;		 
         }   
         System.out.print("value of x : " + x );
         System.out.print("\n");
      }
   }
}

Output

value of x : 11
value of x : 12
value of x : 13
value of x : 14
value of x : 16
value of x : 17
value of x : 18
value of x : 19
value of x : 20

Example 2

In this example, we're showing the use of a continue statement within a for loop to skip an elements of an array to print. Here we're creating an array of integers as numbers and initialized it some values. We've created a variable named index to represent index of the array within for loop, check it against size of the array and incremented it by 1. Within for loop body, we're printing element of the array using index notation. Once 30 is encountered as value, continue statement jumps to the update section of for loop and loop continues.

public class Test {

   public static void main(String args[]) {
      int [] numbers = {10, 20, 30, 40, 50};

      for(int index = 0; index < numbers.length; index++) {
         if(numbers[index] == 30){
            continue;
         }
         System.out.print("value of item : " + numbers[index] );         
         System.out.print("\n");
      }
   }
}

Output

value of item : 10
value of item : 20
value of item : 40
value of item : 50

Example 3

In this example, we're showing the use of a continue statement to skip an element 15 in a do while loop which is used to print element from 10 to 19. Here we've initialized an int variable x with a value of 10. Then in do while loop, we're checking x as less than 20 after body and within while loop, we're printing the value of x and incrementing the value of x by 1. While loop will run until x becomes 15. Once x is 15, continue statement will jump the while loop while skipping the execution of the body and loop continues.

public class Test {

   public static void main(String args[]) {
      int x = 10;

      do {
         x++;
         if(x == 15){
            continue;		 
         }   
         System.out.print("value of x : " + x );
         System.out.print("\n");
      } while( x < 20 );
   }
}

Output

value of x : 11
value of x : 12
value of x : 13
value of x : 14
value of x : 16
value of x : 17
value of x : 18
value of x : 19
value of x : 20
