Question

can you assist me in getting the desired output?

Homework 5-3

Write a Java program that prompts the user for an int n. You can assume that 1 ≤ n ≤ 9. You program should use two embedded for loops that produce the following output:

    1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
.
.
.

This is the code:

import java.util.Scanner;

public class PatternOne {

   public static void main(String[] args) {
       // TODO Auto-generated method stub

Scanner scnr = new Scanner(System.in);
  
//Taking rows value from the user

System.out.println("Please enter a number 1...9 ");

int rows = scnr.nextInt();

System.out.println(" ");

for (int i = 1; i <= 9; i++)
{
for (int j = 1; j <= i; j++)
{
System.out.print(j+" ");
}

System.out.println();
}  
      
   }
      
}

Sir, Please check the screenshot. The code works perfectly as you want.. please elaborate your issue in comments so that i can help..

You can re-check the code below:

import java.util.Scanner;

public class PatternOne {

        public static void main(String[] args) {

                Scanner scnr = new Scanner(System.in);

                System.out.println("Please enter a number 1...9 ");
                int rows = scnr.nextInt();

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

                        System.out.println();
                }

        }

}
