Please help me figure out how to complete this code. I am obviously lost in the world of Java. Thank you!

import java.io.*; public class FindSelectedFiles { public static void main(String[] args) { File f1 = new File("autoexec.bat"); File f2 = new File("SameFolder.java"); File f3 = new File("FileStatistics.class"); File f4 = new File("Hello.java"); testExists(f1); testExists(f2); testExists(f3); //Insert missing code here. } public static void testExists(File f) { System.out.print("File name: " + f.getName() + " "); if(f.exists()) System.out.println("exixts"); else System.out.println("does not exist"); }

//Insert missing code here.

Write an applet that you can display in your browser that simulates a marquee by displaying a string of characters one at a time from right to left across the screen. Use the Thread class sleep method to pause momentarily before each new character displays. When the String message is fully displayed, start the message again. Save the applet as Marquee java in the Chapter 17 folder on your Student Disk
