Question

Okay, so I’m trying to learn how to use the % operator, and I made a simple program that prints out [0] in a loop, and every ten times it goes to the next line, but the first time it doesn’t.

this is the output:

[0][0][0][0][0][0][0][0][0][0][0]
[0][0][0][0][0][0][0][0][0][0]
[0][0][0][0][0][0][0][0][0][0]
[0][0][0][0][0][0][0][0][0][0]
[0][0][0][0][0][0][0][0][0]

this is what the output should be:

[0][0][0][0][0][0][0][0][0][0]
[0][0][0][0][0][0][0][0][0][0]
[0][0][0][0][0][0][0][0][0][0]
[0][0][0][0][0][0][0][0][0][0]
[0][0][0][0][0][0][0][0][0][0]

And this is the code:

public class RemainderLoop {
    public static void main(String[] args) {
        for(int i = 0; i < 50; i++){
            System.out.print("[0]");

            if((i%10) == 0 && i > 0)
                System.out.print("\n");
        }
    }
}

basically, since you are printing the newline AFTER you print the [0], when you get to the 11th item, you print it before the newline, when you want to print it after, because its the 11th.

try this instead

public class Loop {
    public static void main(String[] args) {
        for(int i = 0; i < 50; i++){
            if((i%10 == 0) && i > 0)
                System.out.print("\n");
            System.out.print("[0]");
        }
    }
}

or

public class Loop {
    public static void main(String[] args) {
        for(int i = 1; i < 51; i++){
            System.out.print("[0]");

            if((i%10 == 0) && i > 0)
                System.out.print("\n");
        }
    }
}
