Java code to display Hollow Mirrored Rhombus star pattern

In this article, we will discuss the Java code to display Hollow Mirrored Rhombus pattern program

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 Mirrored Rhombus Pattern using for, while and do-while loop in Java language,

Note – Here,To create a Hollow Mirrored Rhombus pattern, you can use either star or any symbol as you wish

Code to display Hollow Mirrored Rhombus pattern using for loop

This program allows the user to enter the number of rows and any character or symbols then the program displays the Hollow Mirrored Rhombus pattern using for loop in Java language

Program 1

//program to print Hollow mirrored rhombus star pattern
import java.util.Scanner;
public class HolloWMirroredRhombusStar1{//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 character as you wish: ");
//Ask input from the user as character
char ch=scan.next().charAt(0);
//Store the character entered by user
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=1; j<=rows; j++){//inner for loop
   if(i==1 || i==rows || j==1 || j==rows){
   System.out.print(ch);//print characters after space
   }
   else{
       System.out.print(" ");//print space
   }
}
 System.out.print("\n");//move to next line
}
}
}

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