Java Program to Print Inverted Star Pyramid

Write a Java Program to print inverted star pyramid pattern using for loop. This inverted pyramid pattern example uses nested for loops to iterate and display the output.

package ShapePrograms;

import java.util.Scanner;

public class InvertedPyramid1 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Inverted Pyramid Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.println("Printing Inverted Pyramid Star Pattern");
		
		for (int i = rows ; i >= 1; i-- ) 
		{
			for (int j = 0 ; j < rows - i; j++ ) 
			{
				System.out.print(" ");
			}
			for (int k = 0 ; k != (2 * i) - 1; k++ ) 
			{
				System.out.print("*");
			}
			System.out.println();
		}
	}
}

In this inverted star pyramid program, we replaced the for loops with while loops.

package ShapePrograms;

import java.util.Scanner;

public class InvertedPyramid2 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Inverted Pyramid Pattern Rows = ");
		int rows = sc.nextInt();
		

		int i = rows, j, k ;
		while ( i >= 1) 
		{
			j = 0 ;
			while (j < rows - i ) 
			{
				System.out.print(" ");
				j++;
			}
			k = 0 ;
			while ( k != (2 * i) - 1) 
			{
				System.out.print("*");
				k++ ;
			}
			System.out.println();
			i-- ;
		}
	}
}

Enter Inverted Pyramid Pattern Rows = 10

Java Program to Print Inverted Star Pyramid using do while loop

package ShapePrograms;

import java.util.Scanner;

public class InvertedPyramid3 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Inverted Pyramid Pattern Rows = ");
		int rows = sc.nextInt();
		

		int i = rows, j, k ;
		
		do
		{
			j = 0 ;
			do
			{
				System.out.print(" ");
			} while (j++ < rows - i );
			k = 0 ;
			do
			{
				System.out.print("*");
			} while ( ++k != (2 * i) - 1);
			System.out.println();
		} while ( --i >= 1) ;
	}
}

Enter Inverted Pyramid Pattern Rows = 13

In this example, the InvertedPyramidPattern function prints the inverted pyramid pattern of a given symbol.

package ShapePrograms;

import java.util.Scanner;

public class InvertedPyramid4 {
	private static Scanner sc;
	
	public static void main(String[] args) {
		sc = new Scanner(System.in);
		
		System.out.print("Enter Inverted Pyramid Pattern Rows = ");
		int rows = sc.nextInt();
		
		System.out.print("Character for Inverted  Pyramid Pattern = ");
		char ch = sc.next().charAt(0);
		

		InvertedPyramidPattern(rows, ch);		
	}
	
	public static void InvertedPyramidPattern(int rows, char ch) {
		for (int i = rows ; i >= 1; i-- ) 
		{
			for (int j = 0 ; j < rows - i; j++ ) 
			{
				System.out.print(" ");
			}
			for (int k = 0 ; k != (2 * i) - 1; k++ ) 
			{
				System.out.print(ch);
			}
			System.out.println();
		}
	}
}

Enter Inverted Pyramid Pattern Rows = 16
Character for Inverted  Pyramid Pattern = $
