Consider the following class: //class M public abstract class M { private int n; protected double p; public abstract void foo1(); } //end class M   Answer the following questions: 1. If you code the following class: public class P extends M { }    When you compile the code, what is the result? 2. If you code the following class: public class P extends M { public void foo1() { System.out.println(“n is: ” + n); } } When you compile the code, what is the result? 3. If you code the following classes, P and Q: public class P extends M { public P(double newP) { p = newP; } public void foo1() { } }//end class P   public class Q extends P { private int z; public Q(double newP, int newZ) { z = newZ; super(newP); } } When you compile the code, what is the result?

When deserializing an object using the readObject() method, you must cast the return value to the desired class type.

Does the previous question describe a permutation or combination?

You have a tryblock that might throw a user-defined exception TooYoungException or any type of Exception . Put these exceptions in the correct order in the catch blocks       try      {      // statements which might throw any type of Exception      // or TooYoungException      }            catch ([b1]  ex )      {      // statements to handle this      // type of exception      }            catch ([b2]   ex  )      {      // statements to handle this      // type of exception      }      // Statements following the structure

Consider the following two classes:   And assuming that the following variable has been declared: Car mycar = new Truck(); 1. What is the output or result from the following statement? mycar.m1();  2. What is the output or result from the following statement? mycar.m2();  

The area under the normal curve is 74.9% to the left of z.  Find the closest z-score for the given condition.

Consider the following statement: String greeting = “Hello, World!”; //note: there is a space after the camma int len = greeting.replace(“World”, “Dave”).length(); What is the value of the variable len?

What percent of the total area under the normal curve is above z = 1.22?  Round to one decimal place.

To compare two objects in a class to see whether they contains same values for all fields,

Consider the following three classes: public class A { private int number; protected String name; public double price; public A() {  … } private void foo1() { System.out.print(“A version of foo1() called.”); } protected int foo2() { System.out.print(“A version of foo2() called.”); return number; } public String foo3() { System.out.print(“A version of foo3() called.”); return “Hi!”; } }  //end class A   public class B extends A { private char service; public B() {  … } public void foo1() { System.out.print(“B version of foo1() called.”); } public int foo2() { int n = super.foo2(); System.out.print(“B version of foo2() called.”); return n + 5; } public String foo3() { String temp = super.foo3(); System.out.print(“A version of foo3() called.”); return temp + ” foo3.”; } }  //end class B   public class C extends B { public C() {  … } public void foo1() { System.out.print(“C version of foo1() called.”); } }  //end class C Answer the following questions: 1. The instance data members are inherited by B class from A class are [ans1]  and [ans2]. 2. The instance methods are inherited by B class from A class are [ans3] and [ans4].  (For the answers to the following questions, watch out space!) 3. What is the output of the following code sequence? B b1 = new B(); b1.foo1();  [ans5] 4. What is the output of the following code sequence? B b2 = new B(); int n = b2.foo2();  [ans6] 5. What is the output of the following code sequence? B b3 = new B(); System.out.print(b3.foo3());  [ans7] 6. What is the output of the following code sequence? C c1 = new C(); c1.foo1();  [ans8]
