Introduction
In this article, we will explore Java Program to Print Left Triangle Star Pattern. The program in this article prints out the left triangular star pattern as follows:
Example:
Input : n = 5
Output:
* * * * * * * * * * * * * * *
Here the input n to the program from the user or otherwise determines the number of rows of the pattern that will be printed out.
Sample Coe for Left Triangle Star Pattern
import java.io.*; //Java code to demonstrate right star triangle public class Demo { //Function to demonstrate printing pattern public static void starLeft (int n) { int a, b; //outer loop to handle the number of rows //k in this case for (a = 0; a < n; a++) { //inner loop to handle number of columns //values changing according to outer loop for (b = 2 * (n - a); b > = 0; b --) { //printing stars System.out.print (“ ”); } //nested third loop for (b = 0; b < = a; b ++) { //Printing stars System.out.println (“ * “); } //end line System.out.println (); } } //Driver Function public static void main (String args []) { int k = 5; starLeft (k); } }
OUTPUT
* * * * * * * * * * * * * * *
