Fill Matrix with Palindrome Numbers in Java

A class Palindrome contains a 2-dimensional integer array of order m × n where the maximum values for both ‘m’ and ‘n’ is 5. Design the class Palindrome to fill the matrix with first (m × n) palindrome numbers starting from 11.

The details of the members of the class are given below:

Class name: Palindrome
Data members/instance variables:
matrix[][]: stores the array elements.
m: integer to store the number of rows.
n: integer to store the number of columns.
p: to store the first palindrome number as 11.
Methods:
Palindrome(int r, int c): parameterized constructor to initialize the data members m=r,n=c and p=11.
void fill(): fills the matrix with first (m × n) palindrome numbers starting from 11.
void display(): displays the matrix after filling it with palindrome numbers.

Include main() method to create an object of the class and call the methods accordingly to enable the task.
