Question

Problem:

I am using Java Tutorials™ sourcecode for this. This is the source code.

I tried this:

--following with another section of sorted words--
words.add("count");
words.add("cvs");
words.add("dce"); 
words.add("depth");
--following with another section of sorted words--

and it works perfectly. However when I use this:

--just a section of sorted words--
words.add("count");
words.add("cvs");
words.add("dce_iface"); 
words.add("dce_opnum");
words.add("dce_stub_data");
words.add("depth");
--following with another section of sorted words--

It does show dce_iface when I type dce, but when I type _ then following with o or s it shows me something else like dce_offset where the offset comes from words.add("fragoffset"); somewhere in the list.

What can I do to solve this problem? Thank you in advance.

It’s probably because of these lines in the code:

for (w = pos; w >= 0; w--) {
    if (! Character.isLetter(content.charAt(w))) {
        break;
    }
}

_ is not a letter character, so it treats it the same way as a space. You can try changing the condition to:

char c = content.charAt(w);
if (! (Character.isLetter(c) || c == '_')) {
