for-loop skip - GoTo Next Iteration in For Loop in java





continue nested (6)


use continue keyword .

EX:

for(int i = 0; i < 10; i++){
  if(i == 5){
    continue;
   }
}

Is there a token in java that skips the rest of the for loop? Something like VB's Continue in java.




Use the continue keyword. Read here.

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




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();
}



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;
        }
     }
  }



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

You can iterate through the entries in a Map in several ways. Get each key and value like this:

Map<?,?> map = new HashMap<Object, Object>();
for(Entry<?, ?> e: map.entrySet()){
    System.out.println("Key " + e.getKey());
    System.out.println("Value " + e.getValue());
}

Or you can get the list of keys with

Collection<?> keys = map.keySet();
for(Object key: keys){
    System.out.println("Key " + key);
    System.out.println("Value " + map.get(key));
}

If you just want to get all of the values and aren't concerned with the keys, you can use:

Collection<?> values = map.values();
