- Write a Java class Student inherited from Person class. Your class must have the following features: Student - major: String + Student() + Student(name: String, id: int, major: String) + getMajor(): String + Override toString() method: you have to return needed data Fields values. Note: major data members can take only CS for Computer Science, CIS for Computer and Information Systems, CPE for Computer Engineering, SE for Software Engineering, and NES for Network Engineering and Security.2. Write a java program to enable 1-way communication where a String is passed from client. Server counts and prints the number of vowels and consonants in the string received from client. 3. Write a java program to demonstrate session tracking. 4. Write a Java program to implement Lambda Expression with multiple Parameters. Let both the types of parameters be Strings. 5. Write a Java program to implement a superclass Shape and its subclasses Square, Rectangle and Triangle. Calculate the area of each shape using abstract classes and methods.JAVA: According to this diagram, what is the relationship between the Ant and AntColony classes? Group of answer choices: A: AntColony derives from Ant B: Ant contains a reference to AntColony C: AntColony uses Ant objects D: AntColony is an interface that Ant implements
- (JAVA)Write an abstract class for Shape. The intended subclasses are Polygon, Circle, Triangle, and Rectangle. All of these will have a name, an area, and a perimeter. (Consider which methods might be abstract.) Add a toString method that will return the information about the Shape, for example: Triangle, Area: 7.5, Perimeter: 12.0Write a java code that: a) Creates an abstract method in a superclass, then overrides it in a subclass. (Only show the methods in both classes). b) Provides a method PrintInfo () that prints your group info and can be used only in classes of the same package. c) Provides a non-overridden area() that calculates area. (choose a shape)Given the main class Dog, subclass Poodle, and the beginning of the subclass Pug:Instructions for Pug.java Variables: int flabCount – the count of layers on the Pug An invalid value should default this field to 25. A value is invalid if it is nonpositive. boolean isPound – whether this Pug resides in the pound. Poodle bestFriend- a Poodle who is the best friend with the Pug Constructors: A constructor that takes in name, length, weight, stripeCount, isSaltwater, and bestFriend. The bestFriend argument should be deep copied. A constructor that takes in no parameters and sets name to “Pluto”, length to 30.0, weight to 320.0, stripeCount to 14, isPound to false, and bestFriend to null. A copy constructor that deep copies all necessary instance fields. Methods: migrate The pug moves to the opposite kind of living situation if and only if it does not have a best friend. For example, if this pug were now in a pound and it has a best friend, it would not migrate to a…
