In this article, we will discuss the Java Hollow inverted mirrored right triangle star pattern

We can display many types of number, star, Alphabet, Binary patterns using for.while and do-while loop in Java language

In this post, we are going to learn how to print Hollow inverted mirrored right Triangle Star Pattern using for, while and do-while loop in Java language,

Program to print triangle star pattern

Code to display Hollow Inverted mirrored right triangle star using for loop

This program allows the user to enter the number of rows with any symbols then the program displays the Hollow Inverted mirrored right triangle star pattern using for loop in Java language

Program 1

//program to print Hollow inverted mirrored right triangle star pattern
import java.util.Scanner;
public class HollowInvertedMirroredRightTrianleStar1{//class declaration
public static void main(String args[]){//main method

 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.println("Enter the number of rows: ");
//Ask input from the user
int rows=scan.nextInt();
//Store the rows entered by user
System.out.println("Enter Symbol as you wish: ");
char ch=scan.next().charAt(0);
System.out.print("\n");
for(int i=1; i<=rows; i++){//outer for loop 
   for(int j=1; j<i; j++){//inner for loop
   System.out.print(" ");//print space
   }
   for(int j=i; j<=rows; j++){//inner for loop
   if(j==i || j==rows || i==1){
   System.out.print(ch);//print character
   }
   else{
     System.out.print(" ");//print space
   }
   }
   System.out.print("\n");//move to next line
}
}
}

When the above code is executed, it produces the following result
