জাভা কোর্স করার সময় যদি আমি আপনার মত একজন শিক্ষক পেতাম, তবে কোর্স শেষ করার পর কনসেপ্ট বুঝার জন্য পুনরায় আমার ইউটউবে আসতে হইতো না।
Thanks a lot,
you are great,
I hope Allah will make you successful.

Pray for me .

You are a great Bangladeshi programmer brother... Love you. ❤️❤️❤️

exceptional explanation. Thank you Anisul vai for giving us such a very knowledgeable video series in Bangla.

[mdrakibul-gifn]

Thank you sir.this best tutorial of Java

I am trying to watch all of your videos....

I did everything using input (including the summation):

package Array1;

import java.util.Scanner;

public class Array2DDemo {

public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int n, m, o, p, q, r;
System.out.print("Enter array length for row: ");
n = input.nextInt();
System.out.print("Enter array length for col: ");
m = input.nextInt();

int[][] A = new int[n][m];

System.out.println("");
System.out.print("Enter array length for row1: ");
o = input.nextInt();
System.out.print("Enter array length for col1: ");
p = input.nextInt();

int[][] B = new int[o][p];

//Taking A matrix input
System.out.println("");
System.out.println("Enter elements for A metrix:");
for (int row = 0; row < n; row++) {
for (int col = 0; col < m; col++) {
System.out.printf("A[%d][%d] = ", row, col);
A[row][col] = input.nextInt();
}
}

//Taking A matrix input
System.out.println("Enter elements for B metrix:");
for (int row = 0; row < o; row++) {
for (int col = 0; col < p; col++) {
System.out.printf("B[%d][%d] = ", row, col);
B[row][col] = input.nextInt();
}
}
//Printing the B matrix
System.out.println("");
System.out.print("A = ");
for (int row = 0; row < n; row++) {
for (int col = 0; col < m; col++) {

}
System.out.println();
}
//Printing the B matrix
System.out.println("");
System.out.print("B = ");
for (int row = 0; row < o; row++) {
for (int col = 0; col < p; col++) {

}
System.out.println();
}

//Taking array length for the sum
System.out.println("");
System.out.print("Enter summation array length for row: ");
q = input.nextInt();
System.out.print("Enter summation array length for col: ");
r = input.nextInt();

int[][] C = new int[q][r];
//Sum of A+B
System.out.println("");

System.out.print("A+B = ");
for (int row = 0; row < q; row++) {
for (int col = 0; col < r; col++) {
C[row][col] = (A[row][col]+B[row][col]);

}

System.out.println();
}

}
}
