Inheritance

• child object behaving as a parent object.

• by using Extends keyword we wil achive the inheritance

• If we want to create a relationship between two or more classes, we use Inheritance in Java.

What is Inheritance?
Inheritance is a mechanism in Java where one class acquires the properties and behaviors (variables and methods) of another class.

Advantages of using inheritance:

• code reusability(less code duplication).

Example:
parent class:
package inheritance;

public class Employee {

int empId;
int salary;
public static void main(String[] args) {

}

public void work() {

    System.out.println("Employee Work");
}

}

Child class:
package inheritance;

public class Developer extends Employee{
public static void main(String[] args) {
Developer dev1 = new Developer();
dev1.empId=101;
dev1.salary=10000;

    System.out.println(dev1.empId);
    System.out.println(dev1.salary);

    dev1.work();
    dev1.devwork();
}

public void devwork() {

    System.out.println("Coding");
}

}
