how could I put the values I displayed ( IN JAVA CODE ) in an array. as in what the user will see.

(what is the best way to paste my code in here )
so you can view my code?

Re: Java Code Array ( Array to be viewed )
 
here is my code....I need the users to see the output values in an Array

the javac compile works ,....the java does run in dos....it is just I need the output to be an array


Code:

Re: Java Code Array ( Array to be viewed )
 
I need the output to the users ( that they view ) be in an array
how can I make this happen

javac compiler works ...no issues...and the java in dos works.....I just need the output to be an array.
