Addition of 2X2 Matrix in Java

CODE:

public class Main {
	public static void main(String[] args) {
		int a[][]=new int[2][2];
		a[0][0]=1;
		a[0][1]=2;
		a[1][0]=3;
		a[1][1]=4;
		
		int b[][]=new int[2][2];
		b[0][0]=1;
		b[0][1]=2;
		b[1][0]=3;
		b[1][1]=4;
		
        System.out.print("Addition of 2X2 Matrix:\n");
		for(int i=0;i<2;i++){
			for(int j=0;j<2;j++){
				System.out.print(a[i][j]+b[i][j]+" ");
			}
			System.out.print("\n");
		}
	}
}

OUTPUT:

Addition of 2X2 Matrix:
2  4
6  8
