Print a Mirrored Rhombus pattern using do-while loop in Java

In this article, we will discuss the concept of Print a Mirrored Rhombus pattern using do-while loop in Java

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

Display Mirrored Rhombus star patterns Using do-while loop

Code to print mirrored rhombus star pattern

Print a Mirrored Rhombus pattern using do-while loop in Java using for loop — Mirrored Rhombus 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 do-while loop in Java programming language

//Code to display mirrored rhombus star pattern using do-while
import java.util.Scanner;
public class Mirrored_Rhombus_dowhile{//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 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");//move to next line
int i=1;
do{//outer do while loop 
int j=1;
   do{//inner do while loop
   System.out.print(" ");//print space
    j++;
   }while(j<=i);
   j=1;
  do{//inner do while loop
   System.out.print(ch);//print symbol after space
   j++;
} while(j<=rows);
 System.out.print("\n");//move to next line
  i++;
}while(i<=rows);
}
}

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

Code to print Hollow mirrored rhombus star pattern

Program 2

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

//code to print Hollow mirrored rhombus star pattern using do-while loop
import java.util.Scanner;
public class HolloWMirroredRhombus_Dowhile{//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");
int i=1;
do{//outer do-while loop 
int j=1;
   do{//inner do-while loop 
   System.out.print(" ");//print space
    j++;
   }while(j<=i);
   j=1;
   do{//inner do-while loop
   if(i==1 || i==rows || j==1 || j==rows){
   System.out.print(ch);//print characters after space
   }
   else{
         System.out.print(" ");//print space
   }
    j++;
}while(j<=rows);
 System.out.print("\n");//move to next line
  i++;
}while(i<=rows);
}
}

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