extracting file content into array

[phyzix5761]

Hello, I am fairly new to Java and I'm working on some code that is supposed to open a file and copy each line into an array. But the problem is that it returns an IOException and doesn't complete the task. The code is below:

import java.util.*;
import java.io.*;

public class test 
{
	static String[] subjects = {};
	
	public static void main(String[] args)
	{
		loadArrays();
	}
	
	public static void loadArrays()
	{
		String subFile = "data/subjects.txt";
		try
		{
			subjects = readLines(subFile);
		}
		catch(IOException e)
		{
			System.out.println("cant");
		}
	}
	
	public static String[] readLines(String filename) throws IOException
	{
		FileReader fileReader = new FileReader(filename);
		
		BufferedReader bufferedReader = new BufferedReader(fileReader);
		List<String> lines = new ArrayList<String>();
		String line = null;
		
		while((line = bufferedReader.readLine()) != null)
		{
			lines.add(line);
		}
		bufferedReader.close();
		return lines.toArray(new String[lines.size()]);
	}

}

Any help will be appreciated.

You need to supply us with the full exception (plus stack trace) and highlight the line on which it occurs.

getStackTrace() outputs: [Ljava.lang.StackTraceElement;@56e5b723

getMessage() outputs: data/subjects.txt (No such file or directory)

e.printStackTrace();

printStackTrace() outputs:

There you go.
It can't find the file at that location.
Try:

File f = new File("data/subjects.txt");
System.out.println(f.getAbsolutePath());

You'll need to check the spelling etc of the method name, and import the File class.

That will tell you where your code is looking for the file.

It's looking in the correct place but it still returns that error.

ok I figured out the solution. I had the data folder in the wrong place. Thank you for your guidance. It led me to the answer.
