Modify the Student class from chapter 7 as follows (first copy the Student and Address classes to the q3 folder and change the package for them accordingly). Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Provide a zero- parameter constructor that sets each test score to zero. Provide a method calledsetTestScore 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. The driver class is called TestStudent. Modify the driver class main method to exercise the new Student methods.
