## Java continue Statement with Examples ##

In this quick article, we will discuss how and when to use the continue statement with examples.  
The continue statement skips the current iteration of a for, while or do-while loop. The unlabeled form skips to the end of the innermost loop’s body and evaluates the boolean expression that controls the loop.

### 1. Flow Diagram of a continue Statement ###

### 2. continue Statement Inside for Loop Example ###

package net.javaguides.corejava.controlstatements.loops;
    
    public class ContinueExample {
        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("");
            }
        }
    }

This code uses the % operator to check if i is even. If it is, the loop continues without printing a newline. Here is the output from this program:  
0 1  
2 3  
4 5  
6 7  
8 9

### 3. Using continue Statement in while Loop Example ###

package net.javaguides.corejava.controlstatements.loops;
    
    public class ContinueExample {
        public static void main(String args[]) {
            int count = 10;
            while (count >= 0) {
                if (count == 7) {
                    count--;
                    continue;
                }
                System.out.println(count + " ");
                count--;
            }
        }
    }

Output:

10 
    9 
    8 
    6 
    5 
    4 
    3 
    2 
    1 
    0

Note that we are iterating this loop from 10 to 0 for counter value and when the counter value is 7 the loop skipped the print statement and started the next iteration of the while loop.

### 4. Using continue Statement in do-while Loop Example ###

package net.javaguides.corejava.controlstatements.loops;
    
    public class ContinueExample {
        public static void main(String args[]) {
            int j = 0;
            do {
                if (j == 7) {
                    j++;
                    continue;
                }
                System.out.print(j + " ");
                j++;
            } while (j < 10);
    
        }
    }

Output:

0 1 2 3 4 5 6 8 9

Note that we have skipped iteration when j==7.

### 5. Using continue Statement with Labeled for Loop ###

As with the break statement, continue may specify a label to describe which enclosing loop to continue. Here is an example program that uses continue to print a triangular multiplication table for 0 through 9:

package net.javaguides.corejava.controlstatements.loops;
    
    public class ContinueLabel {
        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));
                }
            }
            System.out.println();
        }
    }

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
