Part 1 1. The class Name represents a person's first and last names A. Write the subclass ProperName from the superclass, Name, adding data fields for middle initial and a title such as Ms., Dr. or Sir. B. Provide reasonable constructors, setter, and getter methods for the new C. Override the toString method so that it behaves correctly for the new class. 2. Test your class with the use ProperName file 3. Explain why inheritance is appropriate in the definition of Proper Name but is not a reasonable choice for the definition of the class Nickname, NickName.java 4. Attach your file ProperName.java via the Browse My Computer button and enter your response to #3 in the Comments text box for this lab assignment Part 2 1. The class Circle implements the comparable and Measurable interfaces. Modify the class so that it extends the abstract class Shape. 2. Implement the class Rectangle that extends Shape and implements both the comparable and Measurable interfaces. The dass will have two private data members, length and width Use the area of the rectangle as a basis for comparison when implementing the compare to and equal methods. The toString() method should return a String representation of the length and width of the object 3. Derive the class Square from Rectangle without adding any additional data members. Its parameterized constructor should accept a single value representing a side of the square: it must call the parameterized constructor in Rectangle. You must overriding the following methods: toString getShapeName() 4. Compile and execute the Shape Tester program to test your Circle, Rectangle, and Square classes. 5. To the Shape Tester program, add an array of 12 Shape objects, assign ALL of the Circle, Rectangle and Square objects previously created in the driver to o Write an enhanced for loop that displays the results of a call to the getShapeName() method and a call to the toString() method for each array element of the new array. Compile and execute the Shape Tester o Explain why a method without implementation in the Shape class will compile and execute properly. 6. Inside the block of the enhanced for loop, add a statement that will display a call to the getArea() method for each of the Shape objects in the array of Shapes Compile and execute the Shape Tester Explain the results of this modification to the code 7. To the ShapeTester program, o add an array of Measurable objects, assign ALL of the Rectangle and Square objects created in the driver to the array Write an enhanced for loop that displays the results of a call to the getArea() method for each array element. Compile and execute the Shape Tester Explain why this code will compile and execute properly 8.
