Here is a java program to print a right triangle pattern of natural numbers using for loops.
Java program to print natural number triangle pattern
package com.tcc.java.programs;
import java.util.*;
public class NaturalNumberTriangle {
public static void main(String args[]) {
int rows, i, j, count = 1, star = 0;
Scanner in = new Scanner(System.in);
System.out.println("Enter number
of rows in pattern");
rows = in.nextInt();
for (i = 1; i <= rows; i++) {
for (j = 1; j <= i; j++) {
System.out.print(count + " ");
count++;
}
System.out.print("\n");
}
}
}
Output
Enter number of rows in pattern 7 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28
