    Nobody answers my posts.

    Never mind, this user is someone else. It looked very similar, and the two posts by the two different users were near each other within about a week.

    And also found a person using two user names. Not sure if that's legal. This was a separate person from the spammer.

    gonfreeks is using another id.

    Is that legal? if so, maybe I should try it to get responses to my posts faster.

    It's taking so long I'm thinking of cross posting.

    I have slight problem with a program which turned out to be easy, but I had to figure out some things on the set up and I was under a lot of stress and missed lots of obvious things but now I almost have it. However, I don't have my alternateString() method in my DoublyLinkedList class and I don't have my add(T data) method in my SortedDoublyLinkedList class. I have an idea of how to set them up, but am kinda lost on the specifics.

    Hey I know I posted a message but I still dont get how to do it. My book is being very vague on how to call images and Im really stuck. No one in my class knows how to call one either. Im going to give you my code so you can see.

    http://pastebin.org/225657

    Its a MUD RPG as a project for class.

    I want to have a little map displayed on the JOptionPane depending on which direction they go.
    I have no idea how to do this and need some sort of help please. The instructor has no idea how to do this and I cant find someone to just tell me.

The Groovy in Java

by copeg on June 22nd, 2011 at 09:53 PM
Although scripting languages seem like dime a dozen, there is always that learning curve to become familiar (let alone an expert) with a new language. For those who are more familiar with java - enter groovy. Groovy is a powerful higher level language based upon java, making certain tasks trivial to accomplish relative to the low level java equivalent. The power of groovy comes into play in its ability to plug-into java, and be plugged into from java. Groovy can access class files and libraries,

Logging

by copeg on May 30th, 2011 at 12:22 PM
Logging is a great method to monitor the progress of a program while at the same time maintaining flexibility to control the output. Simply put, logging is just printing out statements during the runtime of an application. In another blog I described a simplistic method for logging - using System.out.println. More advanced logging libraries however go beyond just printing to the console - their flexibility allows control of when, how, and where to log.

Many logging libraries exist,

The Monty Hall Problem

by copeg on May 16th, 2011 at 07:29 PM
The Monty Hall problem is a statistical problem which originates from the television Game show Lets Make a Deal, hosted by Monty Hall. The game is simple: a contestant is presented 3 closed doors, behind one of which is a valuable prize (oftentimes described as a car, whereas the other doors have goats behind them). A contestant chooses a door. The host then opens one of the doors you did not choose, which does NOT contain the prize. Then the host asks - do you want to change your decision? What

How and why an SSCCE?

by copeg on March 27th, 2011 at 10:21 AM
The term SSCCE gets thrown around a lot in online programming forums. Its a simple acronym that stands for Short, Self Contained, Correct Example. But what is so important about an SSCCE? For starters, creating an SSCCE provides a very simple example that clearly demonstrates a given problem, helping one receive help and advice much quicker. But it also goes far beyond just that. Often just the process alone of writing an SSCCE will unveil the problem at hand. But even more important, the process

Debugging with System.out.println

by copeg on March 10th, 2011 at 11:29 AM
System.out.prinln is quite possibly the most useful debugging tool there is - especially for the beginner programmer with no knowledge of other tools such as debuggers, assertions, and/or loggers. System.out.println prints to the command line the values passed to the method as an argument (if an object is passed, the String returned by Object.toString() is printed). For debugging, this tool allows the programmer to evaluate a variable value at a certain position in the code. But that's only the
