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. (c++ language)
Create a class Rectangle. The class has attribute length and width, each of which defaults to 1. It has methods that calculate the perimeter and area of the rectangle. It has set and get methods for both length and width. The set method should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. Write a program to test class Rectangle
in computer programming: java  Create a rectangle class that can compute the area and the sum of its sides.  Create a specialized method that will allow the class to compare other rectangle objects.  The comparison should identify the larger rectangle according to the object’s area.  You should be able to implement the class where the user provides rectangle dimensions.  The program should be able to display which of the rectangle inputs is larger using the Rectangle class method that you defined. Sample output: Enter Length R1:  1 Enter Width  R1:  1 Enter Length R2:  2 Enter Width  R2:  2 Results: R1 Area: 1 R1 Sum: 2 R2 Area: 4 R2 Sum: 4 R2 is the bigger Rectangle!   Note:  All characters in boldface are user inputs.
