Thread: "null" output in console after runing

here is a picture of the eror https://www.filehosting.org/file/det...24108/eror.png

i only throw eror. i wil try try catch and println eror

people alway tel me i should not use try and i heard java graphic device doe not even work half the time

i put it in a jframe

i think it was in my unit clas where the null was. i aded

 unitrectangle = new Rectangle(x.intValue(), y.intValue(), wolfnorthern.getWidth(), wolfnorthern.getHeight());

to my "if unit = wolf" area in the unit clas and i think it fixed it because that was null

eclipse did not crash that time and printed the stack trace or whatever said it was the unitrectangle variable at my wolf iterator or whatever

hmmm now it is saying "null" again. like i said it doe it half the time

i canot even do a

            System.out.println("working");

at the first line of my main method

--- Update ---

here i took all the media file off so it should run in your integrated development envirnment

--- Update ---

oh shoot my run configuration was off in netbean - let me see if i can get some information

--- Update ---

hmmm weird when i clicked run in a new file it was runing my older version which look broken and it doe not show my new file at the set run configuration. i think i got it working in eclipse

hmmm i never got a chance to run that one

i think what hapend was there was something wrong with my

int[]

i switched to ussing an arraylist i think that is what fixed it.

i alway hear people say

int[]

suck and i should use arraylist or maybe even concuenthashmap
