convert a String[] to Arraylist<String> with java
===

I want to convert a string that I get from a file, to an arraylist. I tried it this way, but it doesn't work:

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

    public class Data
    {
	    static File file = DataSaver.file;
	    static List<String> data = new ArrayList<String>(512);
	    public static void a() throws Exception
	    {
	        FileInputStream fis = new FileInputStream(file);
		    DataInputStream dis = new DataInputStream(fis);
		    BufferedReader reader = new BufferedReader(new InputStreamReader(dis));
		    if(!file.exists())
		    {
			    throw new IOException("Datafile not found.");
		    }
		    else
		    {
			    String[] string = reader.readLine().split("$");
			    for(int i = 0; i < string.length; i++)
			    {
				    data.add(string[i]);
			    }
		    }
		    dis.close();
		    System.out.println(data.toString()); //for debugging purposes.
	    }
    }
Ouput:
`[$testdata1$testdata2$]`

Wanted output:
`[testdata1, testdata2]`

File content:
`$testdata1$testdata2$`



Can someone help me?
