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 < list1.length; i++) {        appendedList[i] = list1[i];    }    for(int i = 0; i < list2.length; i++) {        appendedList[i + list1.length] = list2[i];    }    return appendedList;}
Returning an array containing values from two passed in arrays
java;array
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;}
