    Default quite small (make the changelog non-static, i.e. load its content from a file)

    To the Java developers,
    I am currently having trouble with change the Changelogfrom hardcoded to a readout from a text file called "Changelog.txt".
    So far i have made a class called ReadWriteChangelog.java
    and here is the code i placed in: -
    package org.freelords.forms.newgame;
     
    import java.io.*;
    import java.util.*;
     
    import org.freelords.forms.newgame.ChangelogForm;
     
    public class ReadWriteChangelog {
     
     
    public static String getFileContents(String filename) throws IOException {
     
    char[] buf = new char[512];
    int len = 0;
    StringBuilder builder = new StringBuilder();
    FileReader reader = new FileReader(filename);
    while (((len = reader.read(buf, 0, buf.length)) != -1))
    {
    builder.append(buf, 0, len);
    }
    String text = builder.toString();
    BufferedReader buffReader = new BufferedReader(reader);
    while (((len = buffReader.read(buf, 0, buf.length)) != -1))
    {
    builder.append(buf, 0, len);
    }
     
    char[] buffer = new char[512];
    try 
    {
    while (((len = buffReader.read(buf, 0, buf.length)) != -1))
    {
    builder.append(buf, 0, len);
    }
    }
    finally
    {
    buffReader.close();
    }
    return builder.toString();
    }
    }
     
    And what i did on the class ChangelogForm.java i tried to make the class read from the ReadWriteChangelog.java and that is what i written : -
     
     
     
    public void init(Composite parent) {
    super.init(parent);
    File file = new File("I:\\eclipseproject\\eclipseFreelordsUI\\src\ \org\\freelords\\forms\\newgame\\Changelog.txt");
     
    try {
    //".\\FreelordsUI\\src\\org\\freelords\\forms\\newga me\\Changelog.txt"
    Changelog = ReadWriteChangelog.getFileContents();
    } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    }
    description.setText(Changelog);
     
    }
    I am able to operate the Open source game but the code reading the text file can't pass the file contents over to the button to display.If you find a solution to this please reply to this thread or let me know by email.Thank you.
