Problem Solving With Java

Problem Solving With Java-43
If we are lucky, our daily slog at the keyboard is occasionally punctuated with brief glorious moments where it all "just works" and we feel like gods. Taking a break from solving a problem is a good way of generating fresh ideas of things to try. Likewise sleeping on the problem is also good for letting your brain come to grips with the key aspects of a problem. The issue might be a CSS/Layout issue that just simply isn’t worth spending 16 hours on solving, so be careful that you are spending your time effectively. What will happen is when you are reading something like Java Lobby all of these keyword related articles will suddenly jump out you and might contain useful information. Sometimes it helps to temporarily insert additional print statements between each line of code with nothing more than a “line x” statement. If you are having problems with a library or product then sometimes it helps to break out the related code into a program separated from the main application. Another code tidy-up technique is to look at any “Find Bugs” reports you have for the related code and start working with those first. Maybe the problem you are dealing with has already be found and fixed.

It might be cost effective to bring in an expert for a short period of time. The opposite of hiring an expert is to hire a newbie. If you can’t fix the defect then change the requirement. If you can’t find why a particular input file is causing a problem maybe you don’t allow that kind of data into the system. When adopting a new technology understand the basics before jumping into the advanced stuff.

Change key configuration values and make sure it breaks in the way that you think it should because that way you can be more confident (though not absolutely certain) that the configuration settings you do have, are possibly right. If you find yourself dealing with multiple variations of something at the same time then keep a careful note of which combination of things that you’ve tried and be sure to try every combination (if you think it’s required).

Our lives as programmers are a never ending series of one problem after another. The other good thing about taking break from a problem is that it lets your reevaluate how important a problem is. If you ignore the problem what you find happens is that you will be hypersensitive to related keywords for the next week or so. Are you sure you know which line of code is causing the problem.

At the end of the course you will build a program that determines the popularity of different baby names in the US over time by analyzing comma separated value (CSV) files.

Of course often even it’s the right version of the manual that might be the problem since the code has been updated and the manual hasn’t. Of course this is typically called something useful like “Drop Stack Frame” rather than “step backwards”. If you do step over the wrong line of code then look for the debugger feature that lets you step back through the code. Debuggers will let you have conditional breakpoints but I tend to find it easier to just drop in a few lines of temporary code to catch the condition I want to break into the code at. In between these glorious moments we toil through the frustration of one problem after another. Controlling the logging viewed with word wrap on or off can also be helpful. The main server log might not be the only useful log to search through. Another source of log files might be from the operating system itself. For example if you have a complicated data structure to deal with you might include carefully crafted “dump” statements at strategic points in order to get the visibility you need to solve the problem. Write the most accurate and precise problem statement you can. Create a text file with a bunch of notes to yourself about the different things you have tried. If you have support available for a product or library then use it. What you will also find is that the act of writing the support request will prompt you to think about the problem again and you often solve the problem or come up with new things to try before you even hit the send button. Once you’ve got “something” working then it gives you a basis for comparison with the main program. Since you have to spend time with this code anyway, write some new unit tests. A fresh perspective may avoid the problem altogether. Comment out unnecessary code - or at least what you "think" is unnecessary. If you are not sure how the underlying product or library is working then it can useful to introduce little experiments particularly around boundary conditions. Otherwise side-effects from experiment number “3” might affect the “right” answer and so you never actually discover the right solution. Products and libraries can be great when they work and head-banging frustrating when they don’t. We are not programmers, we are just hacking out the first solution that works. If there’s too much logging to read easily, search through the log files for keywords or error codes. Sometimes you want it on and sometime you want it off. Java application servers often produce other log files that might be useful. This can also be quite handy when dealing with multi-thread problems. If the problem is something that you think someone else on the team might know about then ask them. It really doesn’t matter who you explain the problem to it’s the act of explaining that gets your brain to analyse the problem from different angles. By being precise you are challenging your brain to accurately describe the problem which in turn helps you to think of possible solutions. Include snippets of code or configuration settings and also any errors produced 15. Have you ever had a problem where you know you've solved it once before but you can't remember how? Check the Frequently Asked Questions before submitting your support request if there is one. Often the support desk is in a different timezone so when you get to the end of the day put together a support request and let someone else work on it overnight for you. Even if you don’t know how to solve the problem changing the code anyway can be an effective technique for problem solving. It’s helpful to get your brain thinking about the code in the same way that the computer is. You may discover that your understanding of the flow through the code isn't quite what you thought it was.
