Returning an array containing values from two passed in arrays This is a simple piece of code which takes two arrays supplied as parameters, then appends them to  a new array that contains the values from the supplied arrays. Any suggestions for improvement would be greatly appreciated.  

public static int[] append(int[] list1, int[] list2) {
    int[] appendedList = new int[list1.length + list2.length];
    for(int i = 0; i &lt; list1.length; i++) {
        appendedList[i] = list1[i];
    }
    for(int i = 0; i &lt; list2.length; i++) {
        appendedList[i + list1.length] = list2[i];
    }
    return appendedList;
}
You could offload some of the work to Arrays.copyOf and System.arraycopy:

public static int[] append(int[] first, int[] second) {
  int[] result = Arrays.copyOf(first, first.length + second.length);
  System.arraycopy(second, 0, result, first.length, second.length);
  return result;
}
