Java Array Methods. Need Help?

Question

Write the definition of a method reverse , whose parameter is an array of integers. The method reverses the elements of the array. The method does not return a value.

My code:
public void reverse(int [] arr)
{
String store = "";
for (int i = arr.length-1; i>=0; i--)
{
store += arr[i];
}
System.out.print(store);
}

If you pass an array of integers arr1 containing the values 2, 4, 6, 8, 10 to reverse, and print out the array after that, the output will be

10, 8, 6, 4, 2

it says that I dont have the correct output

Answer 1

You are correct. Here it is an a class:
public class ReverseArray{

public static void main(String[] args) {
int[] anArray = {2,4,6,8,10};
System.out.println(reverseArray(anArray));
}

public static String reverseArray(int[] arr){
String store = "";
for (int i = arr.length-1; i>=0; i--){
store += arr[i];
}
return store;
}
}

I think this is what you're after: public class ArrayStuff { /*** * Program: ArrayStuff.java * Purpose: Yahoo! Answers question. * Creator: Chris Clarke * Created: 15.04.2012 ***/ public static void main(String[] args) { int[] theArray = createArray(); printArray(theArray); } static int[] createArray() { return new int[8]; } static void printArray(int[] array) { for(int i=0; i< array.length; i++) System.out.println(array[i]); } }
