Question

Write Java (Zybook 6.6.1)

Print numbers 0, 1, 2, ..., userNum as shown, with each number indented by that number of spaces. For each printed line, print the leading spaces, then the number, and then a newline. Hint: Use i and j as loop variables (initialize i and j explicitly). Note: Avoid any other spaces like spaces after the printed number. Ex: userNum = 3 prints:

public class NestedLoop {
public static void main (String [] args) {
int userNum = 0;
int i = 0;
int j = 0;

/* Your solution goes here */

return;
}
}

Explanation / Answer

NestedLoop.java

public class NestedLoop{
   public static void main (String [] args) {
   int userNum = 0;
   int i = 0;
   int j = 0;
   /* Your solution goes here */
   java.util.Scanner in = new java.util.Scanner(System.in);
       System.out.println("Please enter userNum value: ");
       userNum = in.nextInt();
       String s = "";
       for(i=0; i<=userNum; i++){
           for(j=0; j<i; j++){
               s = s + " ";
           }
           s = s + i + " ";
       }
       System.out.println(s);
   return;
   }
   }

Output:

Please enter userNum value:
3
0
1
