Following Type Eraser, how does the code below look like?                  Before: class GeometricObject {  public double getArea() {return 1.0;}  } public static boolean  equalArea(E object1, E object2)  {     return object1.getArea() ==  object2.getArea(); }                  After: ?

What is the output of the code below? Explain. (Note: there are no compilation errors)   class A {                public int x;                public A(int x) { this.x = x; }                public String toString() { return “x = ” + x; } }   class Super {   public A a;   public Super() {                System.out.println(“Super()”);                foo();   }   public Super (A a) {                System.out.println(“Super(A a)”);                this.a = a;                foo();   }   public void foo() {                System.out.println(“Super.foo()”);                System.out.println(a);   } }   public class Sub extends Super {   public A a;   public Sub() {                System.out.println(“Sub()”);                foo();   }   public Sub (A a) {                System.out.println(“Sub(A a)”);                this.a = a;                foo();   }   @Override public void foo() {                    System.out.println(“Sub.foo()”);                System.out.println(a);   } } public static void main(String[] args) { new Sub(); }

Does the code below compile? Explain.   public class Utils {      public static void main(String[] args ) throws Exception {                           E e = new E();    } }

Given the class hierarchy below. Could the symmetry of equals() be violated? If yes, provide client code that demonstrates that.   class A {   int x;   public A(int x) {this.x = x;}   public boolean equals(Object o) {        if (!(o instanceof A)) return false;        A a = (A)o;        return this.x == a.x;   }        } class B extends A {   int y;   public B(int x, int y) {super(x); this.y = y;} }

If a car’s gas mileage is modeled by a quadratic function

A contract contains a provision that states it will be effective for a “year.” The plaintiff in a lawsuit claims that a “year” is obviously 12 months. The defendant claims that the contract meant a 10-month school year. Parol evidence:

Barry’s Sport Shop calls Champs Tee Shirt Company to order 200 designer tee shirts at $2 per shirt. The next day, Barry decides he can easily sell 100 more. Before the order is filled, he calls to change the order to 300 tee shirts. Champs sends 200. Can Barry force Champs to send the additional 100?

With regard to uncertainty in a contract that falls within the scope of Article 2, which of the following is true?

Mia’s Boutique and Renaldi Co. have dealt with each other for more than 10 years. Mia’s Boutique orders 100 assorted lipsticks at $3.00 each from Renaldi Co. Renaldi sends back a confirmation letter stating that the shipment will be made by UPS rather than by U.S. mail as usual. There is:
