Creating 2D array from all user input

[peek_a_boo]

Hello,

I'm working on a project and I need to write a program that asks the user for the 2 dimensions, and then the program asks the user to enter all the elements by row and column which I've successfully done but I can't figure out how to print out the finished matrix. Here's what I have so far:

import java.util.Scanner;

public class Num_1 {

public static void main (String[] args) {

Scanner scanner = new Scanner (System.in);


int rows;

int columns;

System.out.println("Enter number of rows: ");

rows = scanner.nextInt();

System.out.println ("Now enter the number of columns: ");

columns = scanner.nextInt();

int [][] matrix = new int [rows] [columns];




for (int i = 0; i < rows; i++) {

for (int j = 0; j < columns; j++) {

System.out.println("Enter the number for row " + i + " and column " + j + " : ");

matrix [i][j] = scanner.nextInt();



}




}


}


}

how to print out the finished matrix.

You could use a nested loop with the outer loop iterating through the rows and the inner loop thru the columns.
Use the print method for each element on a row and use println to go to the next row when a row is finished.
