Java Tutorial - Java Continue

continue statement forces an early iteration of a loop. In while and do-while loops, a continue statement causes control to be transferred 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.

Java continue statement

Syntax for Java continue statement

continue;

continue labelName;

The following code shows how to use a continue statement.

 
public class Main {
 public static void main(String[] argv) {
 for (int i = 0; i < 10; i++) {
 System.out.print(i + " ");
 if (i % 2 == 0)
 continue;
 System.out.println("");
 }/*www.java2s.com*/
 }
}

The code above generates the following result.

Example

continue may specify a label to describe which enclosing loop to continue.

 
public class Main {
 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();/*www.java2s.com*/
 continue outer;
 }
 System.out.print(" " + (i * j));
 }
 }
 System.out.println();
 }
}

Here is the output of this program:

Example 2

The following code shows how to use labeled while loop.

//www.java2s.com
public class Main {
 public static void main(String[] args) {
 int i = 0;
 outer: while (true) {
 System.out.println("Outer while loop");
 while (true) {
 i++;
 System.out.println("i = " + i);
 if (i == 1) {
 System.out.println("continue");
 continue;
 }
 if (i == 3) {
 System.out.println("continue outer");
 continue outer;
 }
 if (i == 5) {
 System.out.println("break");
 break;
 }
 if (i == 7) {
 System.out.println("break outer");
 break outer;
 }
 }
 }
 }
}

The code above generates the following result.

Example 3

The following code shows how to calculate Primes with continue statement and label.

public class Main {
 public static void main(String[] args) {
 int nValues = 50;
//fromwww.java2s.com
 OuterLoop: for (int i = 2; i <= nValues; i++) {
 for (int j = 2; j < i; j++) {
 if (i % j == 0) {
 continue OuterLoop;
 }
 }
 System.out.println(i);
 }
 }
}

The code above generates the following result.

Example 4

The following code shows how to use Labeled continue statement to calculate factorial numbers.

/*www.java2s.com*/
public class Main {
 public static void main(String[] args) {
 int limit = 20;
 int factorial = 1;
 OuterLoop: for (int i = 1; i <= limit; i++) {
 factorial = 1;
 for (int j = 2; j <= i; j++) {
 if (i > 10 && i % 2 == 1) {
 continue OuterLoop;
 }
 factorial *= j;
 }
 System.out.println(i + "! is " + factorial);
 }
 }
}

The code above generates the following result.
