Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works.  Next add the following public methods to the Address class and test them from main as you go: Write getters and…

(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…

(Java) Q 5,6 Explain the answer step-by-step . I want to understand how to do it so please include verbal explanation. Thank you!   Part 1 Write the class described below: The name of the class is Student The class has two public member variables: A String called name and a double called gpa  The class has a public member method called printStudent. This method prints out the message: "Hi! My name is " + name + ".\nAnd my gpa is " + gpa It returns nothing Part 2  Now, declare a new Student object named jackie, and assign it the values "Jackie Chan" for the name and 3.5 for the gpa.   Finally insert the object jackie into the below ArrayList: ArrayList<Student> al = new ArrayList<Student>();
