1. A constructor is a special type of method. 2. The following code will result in a compiler error: int n1=2%3 double n2=Dnl; 3. The local variables defined in a method of a class can be referenced by any other method inside the same class. 4. Private methods defined inside a class cannot be used by other methods of this class. 5. Public instance variables can be accessed outside the class. 6. We need to import the Math class in order to use it in our program.

- :Define and implement class Employee. This class should contain the following fields: first name, last name, employee id, hourly pay. This class should contain getters and setters for all its attributes. This class also needs at least one constructor. Implement method computePay() in this class. This method should accept an integer number of hours the employee worked as an input argument and return a floating point value indicating the pay the employee earned. If the number of hours is invalid (e.g. a negative number) this method should throw NumberFormatException. If the number of hours is over 40 then this method should throw a custom exception named TooManyHoursWorkedException. Remember that you will have to define your own exception class for this. Save this class and its definition into a file named Employee.java. Define and implement class EmployeeTest.This class should implement main() method. In the body of the main() method you should create an instance of Employee with the…D: A 21. The method finalize automatically executes when the class object goes out ofI Scope. 22. A mutator method ofa class changes the values of the data members of the class. 23. In Java, the reference this is used to refer to only the methods. not the instance variables of a class.Programming Language= PYTHON 3. Personal Information Class Design 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: John Doe Address: 111 My Street Age: 22 Phone Number: 555-555-1281 Mom's information: Name: Mom Address: 222 Any Street Age: 52 Phone Number: 555-555-1234 Sis's infomation: Name: Jane Doe Address: 333 Her Street Age: 20 Phone Number: 555-555-4444 Dad's information: Name: Dad Address: 222 Any Street Age: 56 Phone Number: 555-254-5611

Add an eat() method for Animal that prints ``Munch munch.'' A make_noise() method for Animal that prints ``Grrr says [animal name].'' Add a constructor for the Animal class that prints ``An animal has been born.'' A class named Cat: Make Animal the parent. A make_noise() method for Cat that prints ``Meow says [animal name].'' A constructor for Cat that prints ``A cat has been born.'' Modify the constructor so it calls the parent constructor as well. A class named Dog: Make Animal the parent.

The MyInteger Class Problem Description: Design a class named MyInteger. The class contains: n [] [] A private int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class. Write a client program that tests all methods in the class.
