Multiple Problems

[ZeroLRS]

There are quite a few errors in my code and I have no idea on how to go about fixing them.
It is a game, and the list of errors is in the "Information" file of the included .zip file.
If you have any advice on improving my coding practice, or an answer on how to fix the bugs, I would be VERY grateful if you would reply to this thread with your knowledge.

Thanks in advance,
ZeroLRS

GameSource.zip

P.S. I will be using this as a reference for the code of my game in the upcoming LD48. Anyone who helps me will have their name included in the credits

Please copy and paste the full text of the error messages here.
Also post your code here.

There is ZeroLRS chance of me downloading your code and wading through it. What Norm said.

[ZeroLRS]

In actuallty, there are no errors per-say. But it will do things like print null values, and not show variable changes.

Here are all of the source files.

And thats it, other than the Information file that reads:

All data within coded by Lucas Spiker (aka ZeroLRS) for GeekFreedom.
 
Thanks to the following for help with this project:
	Norm of http://www.javaprogrammingforums.com/ for coding advice.
	Matthew Estabrook formerly of GeekFreedom for telling me "WE GOTSTA GED DIS DONE GEUYS" and for temporarily loaning me a computer to host a MC Server.
	<YOUR NAME HERE> if you help me with this damn code >.>
 
Buglist:
	All enemy stats equal null.
	Can modify stats, but when accessed, return default values.
	Character name applies under ^
 
Want to change:
	Method for getting enemy stats from location.
 
Misc. Development information:
	enemyTest and enemyTest2 are just separate to look at stats and to test multiple enemy valuesets.
 
General TODO:
	ALOT.

You said you wanted me to post my source....

[Junky]

Still not going to wade through that much code especially since there is little information about what I'm looking for. You have 2 choices: create a SSCCE (google it) or debug your code by placing a bunch of print statements to see what is happening and narrow it down to a certain line/section of code.

[ZeroLRS]

For the first major problem, the bug lies somewhere within locationTest and/or battleTest.
In the second problem, which is only discoverable by either directly sending enemy data to battle test from enemyTest(1or2), and lies somewhere in the way I attempt to display stats in battleTest for enemies, and GameD01 for the player.
I hope this helps.

Execute the program and copy the console contents and paste it here. Be sure to add comments to what you paste here showing what the problem is and add comments to show what you want the output to look like.

Here is a suggestion for how you can make it easier for others to test your code. Change the Scanner definition to automatically provide the answers that you want so that the program will execute and display the problem. Change this line:
Scanner input = new Scanner(System.in);
to something like this:
Scanner input = new Scanner("first answer\nsecond\nthird\n ....for all answers");
Then when someone executes the program, there is no need to know what to answer,
you will have provided ALL of the answer needed to show the problem.

Also change the Random constructor call by giving it a seed so that the random numbers generated will be the same for the testing.


Have you tried debugging the code by adding printlns to show how the variables values change and how the execution flow goes? Since you know what your program is supposed to do, if you print out values, you should be able to see where there is a problem in the logic.
