How do you continue to next iteration in for loop?

If you want to skip a particular iteration, use continue . If you want to break out of the immediate loop, use break.

How do you skip while in Java?

The continue statement skips the current iteration of a loop ( for , while , do... while , etc). After the continue statement, the program moves to the end of the loop.

How do you continue in Java?

continue keyword is used to indicate continue statement in java programming. We can use a break with the switch statement. We can not use a continue with the switch statement.

Can we use continue in if statement in Java?

continue is a keyword. This means the continue statement stands alone in a program. The continue keyword is often part of a Java if statement to determine whether a certain condition is met. You can use a continue statement in a Java for loop or a Java while loop.


continue;

continue; key word would start the next iteration upon invocation

For Example

for(int i= 0 ; i < 5; i++){
 if(i==2){
  continue;
 }
System.out.print(i);
}

This will print

0134

Try this,

  1. If you want to skip a particular iteration, use continue.

  2. If you want to break out of the immediate loop, use break

  3. If there are 2 loop, outer and inner.... and you want to break out of both the loop from the inner loop, use break with label (another question about label).


Example:

continue

for(int i=0 ; i<5 ; i++){

    if (i==2){
   
      continue;
    }
 }

break

for(int i=0 ; i<5 ; i++){
    
        if (i==2){
       
          break;
        }
     }

break with label

lab1: for(int j=0 ; j<5 ; j++){
     for(int i=0 ; i<5 ; i++){
    
        if (i==2){
       
          break lab1;
        }
     }
  }
     

If you want to skip current iteration, use continue;.

for(int i = 0; i < 5; i++){
    if (i == 2){
        continue;
    }
 }

Need to break out of the whole loop? Use break;

for(int i = 0; i < 5; i++){
    if (i == 2){
        break;
    }
}

If you need to break out of more than one loop use break someLabel;

outerLoop:                                           // Label the loop
for(int j = 0; j < 5; j++){
     for(int i = 0; i < 5; i++){
        if (i==2){
          break outerLoop;
        }
     }
  }

*Note that in this case you are not marking a point in code to jump to, you are labeling the loop! So after the break the code will continue right after the loop!

When you need to skip one iteration in nested loops use continue someLabel;, but you can also combine them all.

outerLoop:
for(int j = 0; j < 10; j++){
     innerLoop:
     for(int i = 0; i < 10; i++){
        if (i + j == 2){
          continue innerLoop;
        }
        if (i + j == 4){
          continue outerLoop;
        }
        if (i + j == 6){
          break innerLoop;
        }
        if (i + j == 8){
          break outerLoop;
        }
     }
  }

As mentioned in all other answers, the keyword continue will skip to the end of the current iteration.

Additionally you can label your loop starts and then use continue [labelname]; or break [labelname]; to control what's going on in nested loops:

loop1: for (int i = 1; i < 10; i++) {
    loop2: for (int j = 1; j < 10; j++) {
        if (i + j == 10)
            continue loop1;

        System.out.print(j);
    }
    System.out.println();
}

Use the continue keyword. Read here.

The continue statement skips the current iteration of a for, while , or do-while loop.
