Array Assign Values from a Textfile

Hello,

I have a full functional code that I wrote for my university. I currently assign array values manually:

Code:

---

double[] mortgageAPRArray  = {5.35, 5.50, 5.75};

---

I would like to assign these numbers from a textfile. Could you please help me?

Code:

import java.text.*;
import java.math.*;
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.Date;

Thank you very much in advance,

Ignore your previous code and create a completely new class whose purpose is solely to read a text file and create an ArrayList<Double> with the data read (because you really don't want to create a fixed-size array). To get you going, you should use the Scanner class and read in doubles with nextDouble. Come back if you run into any problems. Good luck.

Dear Fubarable,

Thank you very much for your response, is there any way you can provide me with the source code? I am really short on time!!!

This can ruffle many feathers in here, mine included. We are volunteers who are here to help teach a subject we love, not code-producing servants. Please never ask for someone to do your work for you. Ever. Instead, write your own code, and feel free to ask questions regarding this code you've created as most here will gladly help you with this.

A hard truth but you'd better learn it now: Your time management problems are just that: your problem not ours.

Best of luck and look forward to seeing you here again.

I was able to fix the issue myself!

A hard truth but you'd better learn it now: Your time management problems are just that: your problem not ours.

Best of luck and look forward to seeing you here again.

Congrats, but please remember what I said about asking for source code solutions. I'm sure you'll do better with this in the future.

Sure, thank you very much!

I will keep that in minde!
