Java.util.Arrays
Hey folks! I have this program I need to code and im kinda stuck on it.So bassicly i need to read in an array(1 2 3 4 5...) and i need to reverse it.So the catch is i need to use the recursive int [] reverse method, as well as the copySubArray and appendToArray methods. Im kind of confused on how to do this, the description of the problem says to only use these 3 methods and that is it.So if anyone could give me some guidelines on how to solve this, that would be great.
Thanks!
Re: Java.util.Arrays
My suggestion is to create an array, use one of the methods and print out the results using the Arrays class's toString method:
That will allow you to see what the method does.System.out.println("an ID "+ java.util.Arrays.toString(theArrayName)); // show array's contents
If you have any questions, Post your code (wrapped in code tags) and its output.
If you don't understand my answer, don't ignore it, ask a question.
