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;
        System.out.println(Arrays.toString(myObject.getArray()));
        long endTime = System.nanoTime();
        System.out.print("Total time: " + (endTime - startTime) / 1000 + " microseconds");
    }
}
class C {
    public void timer(int arraySize) {
        long startTime = System.nanoTime();
        System.out.println(Arrays.toString(this.getArray()));
        long endTime = System.nanoTime();
        System.out.print("Total time: " + (endTime - startTime) / 1000 + " microseconds");
    }
}

around this issue Value of action attribute should be URL. The given URL specifies an address to which the data from the form should be sent when a form is submitted.
Use following html code in your jsp page:
<form action="uploadFile" method="post"
                    enctype="multipart/form-data">
<input type="file" name="file" />
<input type="submit" value="Upload file" />
 <servlet>
    <servlet-name>UploadServlet</servlet-name>
    <servlet-class>package.UploadServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>UploadServlet</servlet-name>
    <url-pattern>/uploadFile</url-pattern>
</servlet-mapping>
protected void doPost(HttpServletRequest request, HttpServletResponse response) {
    yourMethod();
}
<form action="upload_file.jsp" method="post" enctype="multipart/form-data">
