Java Conditional Statement: Exercise-18 with Solution

Write a program in Java to print such pattern like right angle triangle with number increased by 1.The pattern like :

1
2 3
4 5 6
7 8 9 10 

Test Data
Input number of rows : 4

Pictorial Presentation:

Sample Solution:

Java Code:

import java.util.Scanner;
public class Exercise18 {

  public static void main(String[] args)

{
   		int i,j,n,k=1;

   		System.out.print("Input number of rows : ");

   		Scanner in = new Scanner(System.in);
		    n = in.nextInt();

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

Sample Output:

Input number of rows : 4
