wish of those help If both classes' behavior is going to be the same, you can simply refer to the object by the superclass type C via Polymorphism, like this :
class C {
    public static void timer(int arraySize, C object) {
        long startTime = System.nanoTime();
        C myObject = object;
        long endTime = System.nanoTime();
        System.out.print("Total time: " + (endTime - startTime) / 1000 + " microseconds");
class C {
    public void timer(int arraySize) {
        long startTime = System.nanoTime();
        long endTime = System.nanoTime();
        System.out.print("Total time: " + (endTime - startTime) / 1000 + " microseconds");

<form action="uploadFile" method="post"
<input type="file" name="file" />
<input type="submit" value="Upload file" />
protected void doPost(HttpServletRequest request, HttpServletResponse response) {
<form action="upload_file.jsp" method="post" enctype="multipart/form-data">
