Two matrices are said to be equal if they have the same dimension and their corresponding elements are equal.

For example, the two matrices A and B given below are equal:

**Matrix A:**

1 | 2 | 3 |

2 | 4 | 5 |

3 | 5 | 6 |

**Matrix B:**

1 | 2 | 3 |

2 | 4 | 5 |

3 | 5 | 6 |

Design a class **EqMat** to check if two matrices are equal or not. Assume that the two matrices have the same dimension.

Some of the members of the class are given below:

**Class name:** EqMat**Data members/instance variables:**

a[][]: to store integer elements.

m: to store the number of rows.

n: to store the number of columns.**Member functions/methods:**

EqMat(int m, int n): parameterised constructor to initialise the data members m and n.

void readArray(): to enter elements in the array.

int check(EqMat p, EqMat q): checks if the parameterised objects p and q are equal and returns 1 if true, otherwise returns 0.

void print(): displays the array elements.

Define the class EqMat giving details of the constructor, void readArray(), int check(EqMat, EqMat) and void print(). Define the **main()** function to create objects and call the functions accordingly to enable the task.

**Program:**

```
import java.io.*;
class EqMat{
private int a[][];
private int m;
private int n;
public EqMat(int m, int n){
this.m = m;
this.n = n;
a = new int[m][n];
}
public void readArray()throws IOException{
InputStreamReader in = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(in);
for(int i = 0; i < m; i++){
for(int j = 0; j < n; j++)
a[i][j] = Integer.parseInt(br.readLine());
}
}
public int check(EqMat p, EqMat q){
int status = 1;
outer:
for(int i = 0; i < m; i++){
for(int j = 0; j < n; j++){
if(p.a[i][j] != q.a[i][j]){
status = 0;
break outer;
}
}
}
return status;
}
public void print(){
for(int i = 0; i < m; i++){
for(int j = 0; j < n; j++)
System.out.print(a[i][j] + "\t");
System.out.println();
}
}
public static void main(String args[])
throws IOException{
InputStreamReader in = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(in);
System.out.print("Number of rows: ");
int rows = Integer.parseInt(br.readLine());
System.out.print("Number of columns: ");
int columns = Integer.parseInt(br.readLine());
EqMat obj1 = new EqMat(rows, columns);
EqMat obj2 = new EqMat(rows, columns);
System.out.println("Enter first matrix elements:");
obj1.readArray();
System.out.println("Enter second matrix elements:");
obj2.readArray();
System.out.println("First Matrix:");
obj1.print();
System.out.println("Second Matrix:");
obj2.print();
EqMat temp = new EqMat(rows, columns);
if(temp.check(obj1, obj2) == 1)
System.out.println("Matrices are equal.");
else
System.out.println("Matrices are unequal.");
}
}
```

Use “pycharm” to run Python programs instead of Sublime Text Editor…

Sir,how to run a python program in sublime text editor?
