How to create a mirror image of a 2D array in Java

Problem Statement

We have provided a list of m x n. here m indicates rows, and n indicates columns). Printing the fresh matrices should result in a mirror reflection of an old matrix.

Inverted image

The first and final columns' items are switched around in a two-dimensional array of m*n that is mirrored. According to the adjacent graphic, the central column is fixed. Keep in mind that the only modified rows are the columns of a mirror copy.

The 2nd and 4th columns will be switched if the matrix is 4*4.

Note:

The center columns would be constant, and the other columns would be switched if several such columns inside the provided matrix were odd.

Java Program for finding the mirror image of the array

Example: MirrorImages.java

// this program is for finding the mirror image of the given array
//importing the required packages
import java.io.*;
import java.util.*;
import java.util.Scanner;  
public class MirrorImages  
{  
public static void main(String args[])   
{  
//establishing a new scanner instance
Scanner sc = new Scanner(System.in);  
System.out.print("Please enter the rows(r): ");  
// reading the input as rows 
int r = sc.nextInt();  
System.out.print(" Please enter the number of the columns(c): ");  
// reading the input as columns  
int c = sc.nextInt();  
// an array was created consisting of m*n order
int array[][] = new int[r][c];  
// a new array for storing the result 
int newArray[][] = new int[r][c];  
System.out.println("Please enter the elements of the array");  
// reading the array elements  
for (int i = 0; i < r; i++)   
{  
System.out.println("Enter thr rows "+ (i+1) + ":");  
for (int j = 0; j < c; j++)   
{  
array[i][j] = sc.nextInt();  
}  
}  
// displaying the input array
System.out.println("The user input array is:");  
for (int i = 0; i < r; i++)   
{  
for (int j = 0; j < c; j++)   
{  
System.out.print(array[i][j] + "\t");  
}  
System.out.println();  
}  
// the elements of the array are exchanging
for (int j = 0; j < c; j++)   
{  
for (int i = 0; i < r; i++)   
{  
newArray[i][c - 1 - j] = array[i][j];   
}  
}  
// displaying the out as the mirror image
System.out.println("Mirror Image of the Given Array is:");  
for (int i = 0; i < r; i++)   
{  
for (int j = 0; j < c; j++)   
{  
System.out.print(newArray[i][j] + "\t");  
}  
System.out.println();  
}  
}  
}

Output

Please enter the rows(r): 3
Please enter the number of the columns(c): 3
Please enter the elements of the arrayEnter the rows 1:
1 2 3
Enter thr rows 2:
4 5 6
Enter thr rows 3:
7 8 9
The user input array is:1
1 2 3
4 5 6
7 8 9
Mirror Image of the Given Array is:
3 2 1
6 5 4
9 8 7
