howdy everyone,
me and 2 other classmate) wish to try to create a simple text based RPG game, basicaly have a drop down box to choose from a couple of opponents and use a dialog box to allow them to attempt to hit the opponent or flee from them, the core idea is to use the math.random method and deduct the result from the opponent's health untill it reaches zero. extremely simple turn based fights, nothing too exciting but lots of work programming wise especialy for beginners such as myself, but theres no time limit on the project thankfully, heh heh.
any suguestions on methods to read up on to save on coding such as other math.X are greatly apriciated by the way, or even sites that might have something similar for inspiriation
..now onto the problem at hand
ive been searching around the net for examples of programs on how to customise dialog boxes, and i found
How to Make Dialogs (The Java™ Tutorials > Creating a GUI with JFC/Swing > Using Swing Components)
beying from the makers of the language, you assume that the programs they give you would work....mine doesnt, possibly on my end is where the problem lies but here is what i downloaded from sun....
i had errors on lines 16 and 33 (not trying to sound cocky or pick apart sun, just a little concirned that my JDK is flawed)
im hoping to get this one working, i find it easier to understand programs both through code and running them

thanks in advance for any help.
also is it possible to use "import javax.swing.*" rather then all those lines? mainly to keep the code clean, i have to explain all of my coding to my teacher, mainly to prove i understand it all and diddnt just copy paste into my program
*edit*
i forgot to mention what error i had, the compile error said "cannot resolve symbol class DialogDemo"
Linear Mode
