如何在java循环中跳过2次迭代

Question

I have a loop where single iteration is skipped using continue :

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

Output would be 0 1 3 4

Based on my criteria above like i==2, I want to get output 0 1 4 . Meaning I want to skip 2 iterations. How do I do that?

Answer 1

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

Increment i by one inside the if statement.

Answer 2

I would stay away from skipping the loop for certain counters. What do you gain from it? Meaning:

for (int i=0; i < 5; i++) {
  if (i != 2 && i != 3) {
    // do whatever needs to be done
  }
}

achieves the exact same thing; without introducing implicit "goto" logic. Why manipulating the control flow this way - without a need?

Answer 3

You can do this:

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

But I agree with others that it is a bad idea to change a loop variable like this.
