Java Program to Print Inverted Star Pattern

In this article, we will understand how to print inverted star pattern. The pattern is formed by using multiple for-loops and print statements.

Below is a demonstration of the same −

Input

Suppose our input is −

Enter the size : 8

Output

The desired output would be −

The inverted star pattern

Algorithm

Step 1 - START
Step 2 - Declare four integer values namely i, j, k and my_input.
Step 3 - Read the required values from the user/ define the values
Step 4 - We iterate through two nested 'for' loops to get space between the characters.
Step 5 - After iterating through the innermost loop, we iterate through another 'for' loop. This will help print the required character.
Step 6 - Now, print a newline to get the specific number of characters in the subsequent lines.
Step 7 - Display the result
Step 8 - Stop

Example 1

Here, the input is being entered by the user based on a prompt. You can try this example live in our coding ground tool .

import java.util.Scanner;
public class InvertedStar{
   public static void main(String[] args){
      int my_input, k, i, j;
      System.out.println("Required packages have been imported");
      Scanner my_scanner = new Scanner(System.in);
      System.out.println("A reader object has been defined ");
      System.out.print("Enter the size : ");
      my_input = my_scanner.nextInt(); System.out.println("The inverted star pattern");
      for ( i = my_input ; i >= 1; i-- ){
         for ( j = 0 ; j < my_input - i; j++ ){
            System.out.print(" ");
         }
         for ( k = 0 ; k != (2 * i) - 1; k++ ){
            System.out.print("*");
         }
         System.out.println();
      }
   }
}

Output

Required packages have been imported
A reader object has been defined
Enter the size : 8
The inverted star pattern

Example 2

Here, the integer has been previously defined, and its value is accessed and displayed on the console.

public class InvertedStar{
   public static void main(String[] args){
      int my_input, k, i, j;
      char my_character;
      my_input = 8;
      System.out.println("The size is defined as " +my_input);
      System.out.println("The inverted star pattern");
      for ( i = my_input ; i >= 1; i-- ){
         for ( j = 0 ; j < my_input - i; j++ ){
            System.out.print(" ");
         }
         for ( k = 0 ; k != (2 * i) - 1; k++ ){
            System.out.print("*");
         }
         System.out.println();
      }
   }
}

Output

The size is defined as 8
The inverted star pattern
