Java Program to Print Inverted Pyramid Pattern of Stars

  • Write a program in Java to print up-side down pyramid pattern of stars.

In Reverse pyramid star pattern of N rows, ith row contains (i-1) space characters followed by (2*i - 1) star(*) characters. Check below mentioned inverted pyramid pattern of 4 rows.

Sample Output for 4 rows
Algorithm to print inverted pyramid star pattern using loop
This C program is similar to pyramid star pattern, except here we are printing the rows in reverse order.
  • We first take the number of rows in the pattern as input from user and store it in an integer variable "rows".
  • One iteration of outer for loop will print a row of inverted pyramid.
  • For any row i, inner for loop first prints i-1 spaces followed by a while loop which prints (2*i - 1) star character.

Java program to print inverted pyramid star pattern


import java.util.*;

public class InvertedPyramidPattern {
    public static void main(String args[]) {
        int rows, i, space, star=0;;

        Scanner in = new Scanner(;
        System.out.println("Enter number of rows in pattern");
        rows = in.nextInt();

        for(i = rows;i >= 1; i--) {
            // Printing spaces 
            for(space = 0; space <= rows-i; space++) {
                System.out.print(" ");
            // Printing stars
            star = 0;
            while(star != (2*i - 1)) {
Enter number of rows in pattern
