Java continue statement

The continue statement is used to control the flow of execution of loops. In while and do-while loops, a continue statement causes control to be transferred directly to the conditional expression that controls the loop. In a for loop, control goes first to the iteration portion of the for statement and then to the conditional expression. For all three loops, any intermediate code is bypassed.

Example:

// continue statement with for loop
public class continueForLoop {
  public static void main(String[] args) {

    for (int i = 0; i < 10; i++) {
      System.out.print(i + " ");

      if (i % 2 == 0) continue;

      System.out.println();
    }
  }
}

Output:

0 1
2 3
4 5
6 7
8 9

continue statement with label for loop

As you can use label break statement, continue can also use the label to describe which enclosing loop to continue.

Example:

Print triangular multiplication table for 0 to 9 using the continue statement.

/ Using continue with a label.
class TriangularMultiplication {
  public static void main(String args[]) {

    outer:
    for (int i = 0; i < 10; i++) {

      for (int j = 0; j < 10; j++) {

        if (j > i) {
          System.out.println();
          continue outer;
        }

        System.out.print(i * j + " ");
      } // inner loop
    } // outer loop
    System.out.println("\nOutside the outer label for loop");
  }
}

Output:

0
0 1
0 2 4
0 3 6 9
0 4 8 12 16
0 5 10 15 20 25
0 6 12 18 24 30 36
0 7 14 21 28 35 42 49
0 8 16 24 32 40 48 56 64
0 9 18 27 36 45 54 63 72 81
Outside the outer label for loop

Java continue statement with do-while loop

Example:

// continue statement with do-while loop
public class ContinueDoWhileLoop {
  public static void main(String[] args) {
    int i = 0;
    do {
      if (i == 5) continue;

      System.out.println("Value of i= " + i);

    } while (++i < 10);

    System.out.println("Outside the do-while loop.");
  }
}

Output:

Value of i= 0
Value of i= 1
Value of i= 2
Value of i= 3
Value of i= 4
Value of i= 6
Value of i= 7
Value of i= 8
Value of i= 9
Outside the do-while loop.

As you can see in the above output. Value of i= 5 is not printed.

Java continue statement with while loop

Example:

/ continue statement with while loop
public class ContinueWhileLoop {
  public static void main(String[] args) {
    int i = 0;
    while (i < 5) {
      i++; // value of i is increased by 1
      if (i == 2) continue;
      System.out.println("Value of i= " + i);
    }

    System.out.println("Outside the while loop.");
  }
}

Output:

Value of i= 1
Value of i= 3
Value of i= 4
Value of i= 5
Outside the while loop.

Java break statement inside nested loop

Java continue statement will continue the inner loop only when if you used the continue statement inside it.

Example:

// demonstrate continue statement with nested loop
public class ContinueNestedtLoop {

  public static void main(String[] args) {
    // Outer loop
    for (int i = 0; i < 3; i++) {
      System.out.println("Outer loop: i= " + i);

      // Inner loop
      for (int j = 1; j <= 3; j++) {
        if (j == 2) continue; // continue the inner loop

        System.out.println(" Inner loop: j= " + j);
      }
    }
  }
}

Output:

Outer loop: i= 0
 Inner loop: j= 1
 Inner loop: j= 3
Outer loop: i= 1
 Inner loop: j= 1
 Inner loop: j= 3
Outer loop: i= 2
 Inner loop: j= 1
 Inner loop: j= 3
