- Java programming language 1. Create a package named P1 and another package named P2. 2. Create an Interface (in the name of Human) inside (P1) (according to the following: • A constant (Type) takes the value mammal. • The Print function has no parameters and does not return a value. 3. Create a Student Class (inside P1) and apply the Human interface (according to the following: • Variables: o (Name): the name. and (No): the number o [Marks]: A 5-digit matrix representing student marks in five subjects. • Functions: o A construct that reads from the keyboard the student's name, number and five marks o Another structure that receives the values of local variables and assigns them. o SetMarks(): reads 5 marks from the keyboard and assigns them to the matrix (Marks).This function is without an instance (Instance or Object. o Print(): prints all student variables and constants. o GetMax(): It is not inherited and prints the highest mark for the student. 4. Create a Class (GraduateStudent)…Computer Science use java language Using what you learned about Polymorphism, create 3 classes assigned Animal names for the superclass. and Dog and Cat for the subclasses. use a method called make sound () and override the output of this method in your subclasses.Create a short program in Java which contains the below information: - Has one abstract and two regular classes - Has two interfaces (the two regular classes have to implement at least one interface - At least one regular class must implement both interfaces - The two classes have to extend the abstract class - The abstract class must have a method - At least one interface must have a method - At least two fields in each class, this includes the superclass - All fields are instantiated within the constructor
- Java program * Interfaces 1. Modify the class Rectangle to implement the Comparable interface, as shown in the following UML class diagrams. Apply the required changes in the class’s header.2. Then, in the Rectangle class override the method compareTo(), so if this object’s area is greater than the specified (given through the parameter) object’s area return 1, if it is less than return -1, and 0 otherwise. 3. Create a test class named Test2. Then complete the following tasks: a. Create an ArrayList and add to it 4 Rectangle objects with different width and height values. b. Print out the elements of the ArrayList. c. Sort the elements of the ArrayList using the static method sort of the class java.long.Collections. This would be possible only, if you implemented the method compareTo() correctly in the Rectangle class. d. After sorting the elements of the ArrayList, print the elements again. 4. Run the Test class. Here is the rectangle's class program public class Rectangle extends…Math 130 Java programming Dear Bartleby, I am a student beginning in computer science.
