You need to post the code. Identify line 51 of Spamicide.java, since line numbers aren't preserved (unless you paste all your imports and everything).

 

Yeah, something is null on line 51. That's all we can say without seeing the code (and you identifying which line is #51)

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

prop.getProperty("IgnoredWords") returns null, because you just initialised an empty java.util.Properties object. Did you mean to use getConfig().getString(...)? You should not be using java.util.Properties at all. There are many other things wrong with this code too, but that is the first one being executed.

 

Hm okay. I'll work on it a little more and hopefully get a better result. Thanks :3

 

Your function:

public ArrayList<String> parseArray(String in, char delimiter)
{
ArrayList<String> parsed = new ArrayList<String>();
String build = "";
int count = 0;
int len = in.length();
while (count < len) {
while ((count < len) && (in.charAt(count) != delimiter)) {
build = build + in.charAt(count);
count++;
}
parsed.add(build);
build = "";
count++;
}
return parsed;
}

could be written as

public List<String> parseArray(String in, char delimiter) {
return Arrays.asList(in.split(delimiter));
}

 

Fo realzeez??? I hate you Java!
