Question

for(int i=0;i<10;i++) { 
    System.out.println(i);
}

In this simple for loop, we initialize i at zero and increment it in every turn. But if we have already increment i, why is my output starting at 0. Didn’t it has to be 0? There is one more indication of that

for(int i=0;i<10;) { 
    i++;
    System.out.println(i);
}

They’re both for loop but why are outputs different?

Answer 1

Probably because

for(int i=0;i<10;i++) { 
    System.out.println(i);
}

is equivalent to:

for(int i=0;i<10;) { 
    System.out.println(i);
    i++;
}
