Need Help - I am not even a beginner in Java :(

Hi ,

Firstly I am at stage 0 in java. Well I have never been into any programming, but it seems like I need a little help to solve a task. I have been given a code and asked to incorporate it to fix an error.

here's the code -

4a5
> import java.net.*;
225c226,227
< String file = fileElem.getAttribute("URI");
---
> String file = URLDecoder.decode(fileElem.getAttribute("URI"), "UTF-8");
> log.info(file);
486c488
< String file = fileElem.getAttribute("URI");
---
> String file = URLDecoder.decode(fileElem.getAttribute("URI"), "UTF-8");


It is a simple URL encoding issue which could be fixed by incorporating this code. But I am too dumb that I don't even know how to do it!
Well there is a program used to decode files, But it has got simple URL encoding issue, which could be fixed by code given above.

Please have a look at the below links so you will get a clear very clear Idea.

The above links are to a program used to decode files. its a freeware, and the source code is too available. the particular version that works for me is 3.3.5 but unfortunately it has a URL encoding issue. The developer of that program gave me the fix to the issue and has asked me to incorporate it and fix it for myself. But I as I said I have never been into any programming, and I really don't understand anything here. But I would really appreciate it if some one will teach me how to do it step-by-step and how to fix it!

Thanks in advance.

What the author gave you is a simple diff patch. You can either pass that through a program called patch, which will change the appropriate lines, or you can do it yourself. Here's what to do:

The line 4a5 means go to line 4 and then add the following code:


Next we have:

From the 225c226,227, we can tell that the change is around line 225 of the file and the letter c means to change that line to something else. (As you may have guessed, the < indicates what should be removed and the > indicates what it should be replaced with) What you're looking for is a line that looks like this:

Replace that line with the following two lines:

Next, we have the following diff:

As you can guess, this means go to line 486 and look in that area for

and replace it with:


Then save and recompile the source code and there you have it.
