Java Program to Print Mirrored Right Triangle Star Pattern

Write a Java Program to print mirrored right triangle star pattern using for loop. This Java mirrored right angled triangle star pattern example uses two for loops nested inside another to display the output.

package ShapePrograms;

import java.util.Scanner;

public class MirroredRightTriangle1 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Mirrored Right Triangle Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Mirrored Right Triangle Star Pattern");
		
		for (int i = 1 ; i <= rows; i++ ) 
		{
			for (int j = 0 ; j < rows - i; j++ ) 
			{
				System.out.print(" ");
			}
			for (int k = 0 ; k < i; k++ ) 
			{
				System.out.print("*");
			}
			System.out.println();
		}
	}
}

In this Java program to display the mirrored right triangle star pattern program, we replaced Java for loops with Java while loops.

package ShapePrograms;

import java.util.Scanner;

public class MirroredRightTriangle2 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Mirrored Right Triangle Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("-- Printing Mirrored Right Triangle Star Pattern --");
		int j, k, i = 1;
		while(i <= rows ) 
		{
			j = 0 ;
			while( j < rows - i ) 
			{
				System.out.print(" ");
				j++;
			}
			k = 0 ;
			while( k < i) 
			{
				System.out.print("*");
				k++;
			}
			System.out.println();
			i++;
		}
	}
}

Java Program to Print Mirrored Right Triangle Star Pattern using do while loop

package ShapePrograms;

import java.util.Scanner;

public class MirroredRightTriangle3 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Mirrored Right Triangle Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("-- Printing Mirrored Right Triangle Star Pattern --");
		int j, k, i = 0;
		do
		{
			j = 0 ;
			do
			{
				System.out.print(" ");
			}while(++j < rows - i);
			k = 0 ;
			do 
			{
				System.out.print("*");
			
			}while( k++ < i);
			System.out.println();
		}while(++i < rows );
	}
}

In this example, the MirroredRightTrianglePat function prints the mirrored right triangle pattern of a given symbol.

package ShapePrograms;

import java.util.Scanner;

public class MirroredRightTriangle4 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Mirrored Right Triangle Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.print("Character for Mirrored Right Triangle Pattern = ");
		char ch = sc.next().charAt(0);
		
		System.out.println("-- Printing Mirrored Right Triangle Pattern --");
		MirroredRightTrianglePat(rows, ch);
		
	}
	public static void MirroredRightTrianglePat(int rows, char ch) {
		for (int i = 1 ; i <= rows; i++ ) 
		{
			for (int j = 0 ; j < rows - i; j++ ) 
			{
				System.out.print(" ");
			}
			for (int k = 0 ; k < i; k++ ) 
			{
				System.out.print(ch);
			}
			System.out.println();
		}
	}
}
