My Java Program Update

This is how far i am with it. Would like to thank Capt.Xander and LCpl.Spartan for all their help so far with this.

Nice state. I did a lot of work up there earlier in the year in Bellevue.

[Guest Ret.Maj.Xander=US=]

few suggestions. Your fnum and answer variables can but put into an array which would clean up the code. Also you need to look into using Else If not just If (someting){//do something} If(something else){//something else}

 

You should also look into global variables for the Right and Wrong variables.

 

Last suggestion is breaking that code out of the Main function and use smaller sub functions to do most of the work then calling them in the main function.

 

Edit: After looking at it more, should there be a different variable for each answer? Couldn't you just use the same variable for each question? Just set it to 0 before you do anything to it in each question.

 

Know that the goal in programming is to maximize functionality and minimize un-needed code.

I could definantly shorten the code a bit. Atm though since im still learning i am not familiar with all options that an experienced eye might catch.

Personally I would do it like this:

 

boolean[] answers = new boolean[10];
answers[0]=(condition1) ? true : false;
