- Write an abstract class, it can be anything well defined from the very basics.Difference Between Abstract class and InterfaceWrite the Talker interface, Animal abstract class, plus the Dog, Cat, Fish, and Radio classes for this Java Program. Talker.java - the interface Talker, which has just one void method called speak() Animal.java - the abstract class Animal, which stores an animal's name. (No abstract methods). It should contain 2 methods: a constructor with 1 argument (the name) a method getName() which returns the name. Dog.java - the class Dog, which extends Animal and implements Talker. It should contain 3 methods: a constructor with no arguments, giving the dog a default name of "Fido" a constructor with 1 argument (the name) a speak() method that prints "Woof" on the screen. Use @Override Cat.java - the class Cat, which extends Animal and implements Talker. It should contain just 2 methods: a constructor with 1 argument (the name) (no default name like dogs have) a speak() method that prints "Meow" on the screen. Use @Override Fish.java - the class Fish, which is an Animal that…
- From a practical standpoint, interfaces outperform abstract classes.What is fundamental difference/s between an abstract classes and interfaceWhen to use abstract classes: To implement the same or different behaviour among multiple related objectsWhen to use interfaces: to implement a contract by multiple unrelated objects in java
- Abstract classes and interfaces may be used interchangeably to specify the behavior of objects.How do you know whether you need an interface or an abstract class?JAVA CLASS AND OBJECT Modify the java program/code given below. 1.) Modify the abstraction example code below by adding another class “TestCarabao” with the necessary methods “label, move, and eat”. abstract class Animal { // abstract methods abstract void move(); abstract void eat(); // concrete method void label() { System.out.println("Animal's data:"); } }Implement the below UML diagram into Java code Note that Employee is an Abstract class and have printInfo() method, and all other classes must have printinfo() methods. SalaryEmployee salary int tax double extends extends calculate_payroll(): number Note: we must find and return the value as: payroll-salary-tax Commission Employee commissionPercent double Employee + id: int +name: string implements + calculate_payroll(): number Note: we must find and return the value as: payroll salary+commissionPercent salary- tax extends -implements D Department deptno int deptnam String printDeptino() Hourly Employee no_of_hours int price per hour double calculate_payroll(): number Note: we must find and return the value as: payrollno of hours price per hour implements > IPayrollCalculator companyld int company Name String + calculate_payroll(): number
