Chapter 4, Problem 6STE

Write a method called advanceYear that could be added to the class DateThirdTry in Display 4.4. The method advanceYear has one parameter of type int. The method advanceYear increases the value of the year instance variable by the amount of this one parameter.

Modify the student class presented in this chapter as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Overload the constructor such that each test score is assumed to be initially zero. Provide a method called setTestScore that accepts two parameters: the test number (1 through 3) and the score. Also provide a method called getTestScore that accepts the test number and returns the appropriate score Provide a method called average that computes and returns the average test score for this student. Modify the toString method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods.

P1. In this question, you are provided a completed superclass – Shape (Do not make any changes to this class!). This class represents generic shapes and has several methods that you will have to override in the Circle and Rectangle subclasses, whose code skeletons are provided as well. You are required to complete these two classes so that they can correctly describe and calculate their attributes. For the Circle class, create the following: A private double instance variable m radius. A constructor that takes two parameters (in the order of color, radius). It should use the parameter for radius to set the m_radius instance variable and then explicitly call the parent class constructor using the super keyword and pass in the color parameter. A method that overrides the calcArea method of the superclass and calculates the area of the circle. The area of a circle can be calculated as 3.14 x r² (where r is the radius). A method that overrides the calcPerimeter method of the superclass and…
2A. Create a Date class with three integer instance variables named day, month, year. It has a constructor with three parameters for initializing the instance variables, and it has one method named daysSinceJan1(). It computes and returns the number of days since January1ofthe same year, including January 1 and the day in the Date object. For example, if day is a Date object with day = 1, month = 3, and year = 2000, then the call date.daysSinceJan1( ) should return 61 since there are 61 days between the dates of January 1, 2000, and March 1, 2000, including January1 and March 1. Include a DateDemo class that tests the Date class. Don't forget leap years. %3D %3D
