Question

In java I want to have my output show up in a text file called "output.txt".

This is my print method for my array and it works as it should when it prints out in the console.

public void printArray(int matrix[][])
   {
   for (int row = 0; row < matrix.length; row++)
   {
   for (int column = 0; column < matrix[row].length; column++)
   {
   System.out.print(matrix[row][column] + " ");
   }
   System.out.println();
   }
   }

I would like to know what I need to do in this to make it to where I can have my output show up in the text file I create instead.

Explanation / Answer

=======================================

Program name WriteToFile.java

=======================================

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Scanner;

public class WriteToFile {

   public static void main(String[] args) {

       int m, n;
       Scanner sc = new Scanner(System.in);
       System.out.print("Enter Number of rows :");
       m = sc.nextInt();
       System.out.print("Enter Number of columns :");
       n = sc.nextInt();

       // Declaring multi dimensional array with given dimensions
       int array[][] = new int[m][n];

       System.out.println("Enter matrix elements:");
       for (int i = 0; i < m; i++) {
           for (int j = 0; j < n; j++) {
               array[i][j] = sc.nextInt();
           }
       }

       WriteToFile writer = new WriteToFile();

       writer.printArray(array);
   }

   public void printArray(int matrix[][]) {

       try {
           FileWriter fileWriter = new FileWriter("output.txt");

           BufferedWriter bufferedWriter = new BufferedWriter(fileWriter);

           for (int row = 0; row < matrix.length; row++) {
               for (int column = 0; column < matrix[row].length; column++) {
                   bufferedWriter.write(matrix[row][column] + " ");
               }
               bufferedWriter.newLine();
           }

           bufferedWriter.close();
           System.out.println("Writing data to output.txt completed");
       } catch (IOException ex) {
           ex.printStackTrace();
       }

   }

}
