Problem with nested for loops

[subzero1012]

Hello,
Could you please help me figure out how to solve this problem?

Write nested for loops that produce the following output:

000111222333444555666777888999
000111222333444555666777888999
000111222333444555666777888999

This is what I have, but it's wrong.

for(int i = 1; i <= 3; i++){
    for(int j = 0; j <= 9; j++){
        for(int k = 1; k <= 3; k++){
           System.out.println(j);
        }
    }
}

How is your code wrong? What is it doing incorrectly?

And have you ever used System.out.print(...)? Do you know the difference between the behavior of this method and the println(...) method?

The orginial code was printing one character per line. Didn't know there was a print method! It now works as written below.

for(int i = 1; i <= 3; i++){
    for(int j = 0; j <= 9; j++){
        for(int k = 1; k <= 3; k++){
            System.out.print(j);
            if(j==9 && k==3) 
               System.out.println("");
        }
    }
}

Thanks!

You're welcome, but you don't even need the if block, simply move the println outside of the inner loops.
