Program to Print Mirrored parallelogram star pattern using for loop in Java

In this article, we will discuss the concept of Program to Print Mirrored parallelogram star pattern using for loop in Java

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

Display Mirrored parallelogram star patterns Using for loop

Code to print mirrored parallelogram star pattern

Program to Print Mirrored parallelogram star pattern using for loop in Java — Mirrored parallelogram star pattern

Program 1

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

//Program to print Mirrored parallelogram pattern using for loop
import java.util.Scanner;
public class MirroredparallelogramStarFor{//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 to rows
int rows=scan.nextInt();
//Reading the number of rows entered by user

System.out.println("Enter the number of columns: ");
//Ask input from the user to columns
int columns=scan.nextInt();
//Reading the number of columns 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<=columns; 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

Code to print Hollow mirrored parallelogram star pattern

Program 2

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

//Program to print Hollow Mirrored parallelogram pattern using for
import java.util.Scanner;
public class HollowMirroredparallelogramStarfor{//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 to rows
int rows=scan.nextInt();
//Reading the number of rows entered by user

System.out.println("Enter the number of columns: ");
//Ask input from the user to columns
int columns=scan.nextInt();
//Reading the number of columns 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<=columns; j++){//inner for loop
   if(i==1 || i==rows || j==1 || j==columns){
       System.out.print(ch);//print symbol after space
   }
   else{
       System.out.print(" ");//print symbol after space
   }
   
}
 System.out.print("\n");//move to next line
}
}
}

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