In this tutorial, we will write a program to print an inverted equilateral triangle in java. Before that, you may go through the following topic in java.

• for loop in java

It is a Java Program to Print Reverse Pyramid Star Pattern or you can say upside-down equilateral triangle pattern in java.

The program takes the user input for the number of rows to be taken to print the reverse equilateral star pattern.

Example:

Input: number = 7   
Output:
 *************  
 ***********   
  *********    
   *******

Java program to print Inverted Equilateral Star Triangle

import java.util.Scanner;

public class Main
{
  public static void main(String[] args)
  {
    int num, i, j, k;
    Scanner sc = new Scanner(System.in);

    System.out.print("Enter the no. of rows: ");
    num = sc.nextInt();

    for (i = num; i > 0; i--)
    {
      for (j = 0; j < num - i; j++)
      {
        System.out.print(" ");
      }

      for (k = 0; k < i; k++)
      {
        System.out.print("*" + " ");
      }

      System.out.print("\n");
    }
  }
}
