Java, recursively reverse an array

Question

I haven\'t found anything with the specific needs of my function to do this, yes, it is for homework.

So I have:

public void reverseArray(int[] x) {
         


        

Answer 1

This is probably the easiest way, not the fastest, but probably the easiest.

A whole program would look something like this:

public static void main(String [] args)
{
    BackwardsArray back = new BackwardsArray();
}

public BackwardsArray()
{
    int [] a = {1,2,3,4,5,6,7,8,9};
    printBackwards(a);
}

void printBackwards( int [] b)
{
    print(b,b.length-1);
}

void print(int [] b, int pos)
{
    System.out.println(b[pos]); // prints last item
    if(pos != 0)
    {
        print(b,pos-1);
    }
}

Hope it helps!
