State one advantage of ArrayList compared to LinkedList. Next, state one advantage of LinkedList compared to ArrayList.

The rules of encapsulation suggest that instance variables should be private.

What is the output of the main method below? If there is an error (compiler or runtime), state the kind and circle the line(s) that cause it. public class A { //In A.java    public A() {        System.out.println(“A here”);    }    public void methodA(Object obj) {        System.out.println(“X”);    }}public class B extends A { //In B.java    public B() {        System.out.println(“B here”);    }    public void methodA(Object obj) {        super.methodA(null);        System.out.println(“Y”);    }    public void methodB(Object obj) {        System.out.println(“Z”);        this.methodA(null);    }}public class FinalExam { //In FinalExam.java    public static void main(String[] args) {        A a = new B();        a.methodA(new A());        B b = new B();        b.methodB(new B());    }}

What kind of exception does the following program throw? (select only one) public class Exceptional { public static void main(String[] args) { String s = null; System.out.println(s.toString()); }}

To describe the natural ordering of instances of a class, the class must implement the _____________________________ interface.

Explain why it is important to have a correct order of catch blocks after a try block. Write some example code where the catch blocks are in the incorrect order and it prevents the code snippet from running the correct code based on the runtime error.

In Java, casting only changes the object type while the declared type never changes.

Write the class header, Node class, and variables for a generic Linked List class, (named LinkedList). The class will receive one type parameter, E. It should have a private inner class, a generic Node class. It will have the instance variables data (of type E, the type parameter) and next (which will point to an instance of the inner class). It will have a 2-arg constructor receiving them in that order and setting them. The variables and constructor will have private visibility. Getters and setters are not required nor allowed. It should have the instance variables head and size with private visibility. Getters and setters are not required nor allowed. On the next question you’ll add a method to the LinkedList class

All checked exceptions must be handled or propagated in order for a Java program to compile.
