Java program to print Mirrored and Hollow mirrored Rhombus pattern using for loop

Java program to print Mirrored and Hollow mirrored Rhombus pattern using for loop

In this article, we will discuss the concept of Java program to print Mirrored and Hollow mirrored Rhombus pattern using for loop

In this post, we are going to learn how to write a program to print  mirrored rhombus and Hollow mirrored rhombus patterns using for loop in Java programming language.

 

Display Mirrored Rhombus  star patterns Using for loop

Code to print mirrored rhombus star pattern

Program 1

This program allows the user  to enter the number of rows , and any symbols then it will display  the mirrored rhombus    star pattern using for loop in Java programming language

//program to display mirrored rhombus star pattern using for
import java.util.Scanner;
public class MirroredRhombusStar1{//class declaration
public static void main(String args[]){//main method
//main method is a pre-defined method
 Scanner scan=new Scanner(System.in); 
    //create a scanner object for input from user
    
System.out.println("Enter the number of rows: ");
//Ask input from the user
int rows=scan.nextInt();
//Reading the number of rows entered by user
System.out.println("Enter Symbol as you wish: ");
//Ask input from the user as symbol
char ch=scan.next().charAt(0);
//Reading the symbol 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
   System.out.print(ch);//print symbol after space
}
 System.out.print("\n");//move to next line
}
}
}

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

Program 2

This program allows the user  to enter the number of rows and any symbols then it will display  the Hollow mirrored rhombus    pattern using for loop in Java programming language

//program to display Hollow mirrored rhombus star pattern using for loop
import java.util.Scanner;
public class HollowMirroredRhombusStarFor{//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();
//Reading the number of 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);
//Reading 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 result
