ContinueDemo.java

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

        /*
         * 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.
         */

        for (int i = 0; i < 2; i++)
        {
            System.out.println("i : " + i + "\n");
            for (int j = 0; j < 3; j++)
            {
                if (j == 1)
                {
                    continue;
                }
                System.out.println("j : " + j);
            }

            System.out.println("------------------------------");
        }

    }
}

Output

i : 0

j : 0
j : 2
------------------------------
i : 1

j : 0
j : 2
------------------------------
