Simple Matrix Printing Program

Write a Java Program to print Matrix with or without User Interaction  

 1. Matrix printing without user interaction

public class M1 {
	public static void main(String[] args) 
	{
		int matrix[][] = {{1,2,3}, {4,5,6}, {7,8,9}};
		
		int row = matrix.length;
		int col = matrix[0].length;
		System.out.println("\nMatrix Printing...");
		
		for(int i=0; i<row;i++)
		{			
			for(int j=0; j<col;j++)
				System.out.print(matrix[i][j]+" ");			
			System.out.println();
		}		
	}
}
OUTPUT

Matrix Printing...
1 2 3 
4 5 6 
7 8 9 

 2. Matrix printing Using Scanner (Taking input from user) 

import java.util.Scanner;
public class M2 {
	public static void main(String[] args) {
	 Scanner s = new Scanner(System.in);
	 System.out.println("enter rows");
	 int m = s.nextInt();
	 System.out.println("enter coloumn");
	 int n = s.nextInt();	 
	 int mat[][] = new int[m][n];
	 System.out.println("enter elements..");
	 	for(int i=0; i<m;i++){
			for(int j=0; j<n;j++)
				mat[i][j]=s.nextInt();
		}
	 	System.out.println("................");
	 	for(int i=0; i<m;i++){
			for(int j=0; j<n;j++)
				System.out.print(mat[i][j] +" ");
			System.out.println();
		}
	}
}
OUTPUT

enter rows

enter coloumn
3
enter elements..
