Chapter 5.2, Problem 16STQ
Give the complete definition of a class called Person that has two instance variables, one for the person’s name and the other for the person’s age. Include accessor methods and mutator methods for each instance variable. Also, include a method that sets both the name and age of a person. There are no other methods.

can you help me how to test this
Part 1: Test Program
Write a program to test all test cases outlined in the test plan. For each method (unit) being tested, ensure your client program provides output clearly describing the method being tested along with the expected and actual result.
When testing constructors, verify the results by calling an accessor method of the class.
When testing mutators, use the accessor method to verify the state change.
When a test fails (actual does not match the expected), correct the method code, then re-test. Keep in mind that a poorly written test can produce inaccurate test results. If a test fails, ensure you have written the test correctly before modifying your unit code.
Output Requirement
For each method (unit), output the method signature.
For each test, output the following:
Test number
Outcome description
Expected result
Actual result
Leave one blank line between each test.
Sample
StudentGrades(int) Test #1 - Initialize grades array…
Change the classes "Line" and "Matrix" as follows:
a. all static properties of classes should be changed only inside class
methods;
b. select one or more sub methods (if it has not been done before) and
arrange them as static methods.
THE BELOW IS IMPORTANT
Rewrite the above code so that
It has all of the correct access modifiers for good encapsulation.
Your code obeys the principle of encapsulation that obliges you to put each method in the proper class.
Your code uses NO getters and NO additional classes or methods. You are welcome to modify any existing methods (including signatures and bodies) and/or move them between the existing classes.
Your code DOES NOT modify any of the constructors.
Important notes:
You DO NOT have to write a main method.
You DO NOT have to write tests.
You DO NOT have to write Javadocs.
You DO NOT have to write interfaces to encapsulate data structures.
There should be no incorrect syntax or other compile-time errors.

- Note: Write a Java program given below Question # 1: Define a class for Students with field name, age, marks. Define getter and setter for all the fields. In the setter method, if age is less than 0, print that Age is less than zero. Similarly, if marks is less than zero or greater than 100, print in correct marks and don’t assign marks to member variable. In the Test class, create student’s object and assign the marks and age to appropriate values. Try assigning incorrect values to check if getter and setter methods work as expected.arrow_forwardGive source code and output alsoarrow_forwardCreate a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…arrow_forward
- Need help asap:arrow_forwardDesign a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, write a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information. my information: name= doe address= 51 any street age= 19 number= 732 810 9995 friends info: name= ella address= 174 any street age= 22 number= 732 895 3586 friends info: name= meg address= 34 any street age= 20 number= 732 337 5580arrow_forwardPrompt We have learned how to use accessor and mutator methods to access private class member data. It is possible to instead make the class members public, which would allow other programs to directly retrieve and modify the class member data without needing to write the accessor and mutator methods. This is usually considered bad practice. Why do you think that is? What do you think the benefits are to writing accessor and mutator methods instead of just leaving the variables public? Below is the definition for a class called Counter. Define a new method for this class called "findDifference". This method should take another Counter object as an argument and return the difference in the counts between the counter being called and the one passed as an argument. The difference should be given as an absolute value (not returned as a negative). See below the class definition for examples of this method being used. public class Counter {private int count;public Counter() {count =…arrow_forward
