    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?

    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:

    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.

    Code:
