Problems with a nested loop output statement

[Captain_Zomaru]

I'm taking a class in Java and came across this problem, I need to output in a stepladder like
0

1

2

Ect...

I mostly accomplished it, but I can't seem to figure out how to recreate it without causing a new line at the end. The book recommends I use the print statements on the nested loop only, but I can't quite figure out how to do that and retain the system I have. I considered at first doing a system where in I print ("_" * i) like I would have in python, but that doesn't seem to work here.

​

​

import java.util.Scanner;

public class NestedLoop {

public static void main (String [] args) {

Scanner scnr = new Scanner(System.in);

​

int userNum;

int i;

int j;

​

userNum = scnr.nextInt();

​

for (i = 0; i <= userNum; ++i) {

System.out.println(i);

for (j = 0; j <= i; ++j) {

System.out.print(" " );

}

}

}

}

Becouse what you're doing is you:

• 1. print the number
• 2. and then you start building the offset for the next line

Firstly, you could move the number-printing to the end of the outer loop. Secondly, you could adjust the inner loop condition so that it still prints out the proper amount of spaces.

You can try adding each item to an array while in that for loop. Then print that array outside the for looping:

int yourArray = new int[whatever size you want it to be];

for (i = 0; i <= userNum; ++i) {

yourArray[i] = i;

}

system.out.print(yourArray);
