Use continue to end this cycle

4.4.2 Use continue to end this cycle

The Continue function is a bit like a break, except that continue just stops the loop and then starts the next one. And the break is a complete termination of the loop. It can be understood that the role of continue is to skip over the remaining statements in the secondary loop and start a new loop again. For example, the following program demonstrates the use of continue:

List of programs: Codes/04/4-4/testcontinue.java public class testcontinue {public static void Main (string[] args) { //A simple for loop for (int i = 0; i < 3; i++) { System.out.println ("I's value is" + i); if (i = = 1) { //Skip the remaining statements of this cycle continue; } SYSTEM.OUT.PRINTLN ("output statement after Continue");} }

Run the above program and see the following results:

I's value is 0 continue after the output statement I value is 1 i the value is 2 continue after the output statement

From the results above, when I equals 1 o'clock, the program does not output the "Continue output statement" string, because when the program executes to continue, the code behind the continue statement in the secondary loop is ignored. In this sense, if you put a continue statement on the last line of a single loop, the continue statement doesn't make any sense-because it simply ignores a blank and ignores any program statements.

Similar to the break, continue can also be followed by a label that directly ends the cycle of the loop identified by the label, and starts the next loop again. For example, the following code:

List of programs: Codes/04/4-4/testcontinue2.java public class TestContinue2 {public static void Main (string[] args) { //outer Loop outer: for (int i = 0; i < 5; i++) { //inner loop for (int j = 0; J < 3; J +) The value of c11/>{System.out.println ("i) is:" + i + "J" is: "+ j"; if (j = = 1) { //jump out of the loop specified by the outer label. continue outer }} } }

Running the above program, you can see that the value of the loop variable will not exceed 1, because whenever J equals 1, the continue outer statement ends the cycle of the outer loop, starting the next loop directly, and the inner loop does not have the opportunity to perform the completion.

Like a break, a continue tag must also be a valid label, that is, the label should normally be defined before the outer loop of the continue's loop.
