This is the code that made me to quit programming. I took me 12 hours to code this on netbeans but I could not fix it. Please somebody should help me fix this error. I will be grateful to you.

I need the CCS to start the criticism because this code knocked me out of programming entirely when I was frustrated. I need solution to it plus a new suggestion to improve it.

Hi @Waliya --

CCS Working Group may not be the best place to get specific debugging advice on Java programming -- in general it is more for talking about code in culture, not helping to debug fix programs that aren't working.

If you do want help with your program, I would recommend a site like Stackoverflow. To get best results there, first search the error message and make sure there isn't already an answer to your question. Then, if posting a question, make sure you have posted an MCVE -- a Minimal, Complete, Verifiable Example. In particular, when posting to a forum for code help, notice this part of the advice:

Describe the problem. "It doesn't work" is not a problem statement. Tell us what the expected behavior should be. Tell us what the exact wording of the error message is, and which line of code is producing it. Put a brief summary of the problem in the title of your question.

So people trying to help would want to know what you expected the code to do once it was working correctly -- and, if you are modifying existing code, it might also help them to know where you got it from and what you were trying to change about it when it broke.

jeremydouglass · January 2018

One aspect of your question that in my opinion would make a good CCS topic of general interest is "code that makes people quit" -- quit a language, quit programming, et cetera. So for example it might be productive as a general discussion to ask forum members to reflect of stories of the specific code examples or languages tools etc. that made them quit something, or that they saw stopping or frustrating others. I would guess that many people have similar stories....

Thanks sir @jeremydouglass The code I posted above is supposed to open a GUI frame for someone to upload .txt extension document in order to read it. But, the BufferedReader code on line 107 refused to convert the filename and the results was read thus:
FileReader.java:107: error: incompatible types: FileReader cannot be converted to Reader
BufferedReader br = new BufferedReader(reader);
^
Note: Some messages have been simplified; recompile with -Xdiags:verbose to get full output
1 error. This complexity was what knocked me out of coding.

Howdy, Stranger!
