JAVA CODE

Write a program which has a 3D array and prints the integers from the array. Then then convert the output into a file using filewriter

Answer 1

import java.io.FileWriter;
import java.io.IOException;

public class Array3DToFile {
    public static void main(String[] args) {
        int arr[][][] = {
                {
                        {1,2,3,4},
                        {5,6,7,8}
                },
                {
                        {8,7,6,5},
                        {4,3,2,1}
                }
        };

        for(int i = 0;i<arr.length;i++){
            for(int j = 0;j<arr[i].length;j++){
                for(int k = 0;k<arr[i][j].length;k++){
                    System.out.print(arr[i][j][k]+"\t");
                }
                System.out.println();
            }
            System.out.println();
        }


        FileWriter fw= null;
        try {
            fw = new FileWriter("output.txt");
            for(int i = 0;i<arr.length;i++){
                for(int j = 0;j<arr[i].length;j++){
                    for(int k = 0;k<arr[i][j].length;k++){
                        fw.write(""+arr[i][j][k]+"\t");
                    }
                    fw.write("\n");
                }
                fw.write("\n");
            }
            fw.close();

        } catch (IOException e) {
            e.printStackTrace();
        }

    }
}
