QuestionPlacing 2DArray Values into x, y locations Pin

Member 135019553-Nov-17 7:35 
Hello! I'm having a bit of trouble with 2-dimensional arrays. Currently, I am using netBeans 8.0.

I don't believe I need a loop to do what I'm trying to achieve, but nonetheless I'm stuck. Here is the code for reference:
Java
<pre>
package nb.test.gamepackagev1;
import edu.sjcny.gpv1.*;
import java.awt.Color;
import java.awt.Graphics;
import java.io.File;
import java.io.IOException;
import java.util.Scanner;

public class Homework4 extends DrawableAdapter
{   static Homework4 ge = new Homework4(); 

    static Character[][] parade = new Character[4][2];    

    static int[][] aNum = new int[4][2];
    static GameBoard gb = new GameBoard(ge, "Homework 4 by Sam Tahiri");
    public static void main(String[] args) throws IOException
    {
        showGameBoard(gb);
       
        int newX, newY;
        for (int i = 0; i < parade.length; i++) {
            parade[i][0] = new Character[4][2];
            newX = aNum[i][0];
            newY = aNum[i][1];
            parade[i][0].setX(newX);
            parade[i][1].setY(newY);
        }        
        readArray();
        
    }
    
    public static void readArray() throws IOException {
        File fileObj = new File("Array.txt");
        if (!fileObj.exists()) {
            System.out.println("File does not exist");
        }
        else {
            Scanner fileIn = new Scanner(fileObj);
        for (int i = 0; i < aNum.length; i++) { 
            //System.out.println(fileIn);
            int x = fileIn.nextInt();
            int y = fileIn.nextInt();
            System.out.println(x + " " + y);
           
            aNum[i][0] = x;
            aNum[i][1] = y;
//            parade[i].setX(newX);
//            parade[i].setY(newY);            
            for (int j = 0; j < parade.length; j++) {
                parade[i][0].setX(x);
                parade[i][1].setY(y);
            }
        }
        }
        System.exit(0);
    }
//    
//    public void moveAll(Character[] Character) {
//        for (int i = 0; i < aNum.length; i++) {
//            Character[i].setX(aNum[i][0]);
//            Character[i].setY(aNum[i][1]);
//        }        
//    }
    
    public void draw(Graphics g) {
        for (int i = 0; i < parade.length; i++) {
            parade[i][0].show(g);
            parade[i][1].show(g);
        }
    }
    
}


Ultimately, what I would look to do is to place the values of the array aNum[4][2] into each of the 4 objects of parade. The file, Array.txt, has 4 rows of 2 columns, therefore, 4 sets of [x][y] coordinates for the 4 objects I would like to create.

How can I place these values into said objects?
For example, if the first line of the array aNum is 120, 150, then the first object, parade, would be located at (120, 150) on the GameBoard. Thank you so much for helping me out!!
