Inheritance in Java. Inheritance Inheritance is the process of reusing the code used in. The class from. which the subclass is derived is called a superclass (also a base.
Every class has one and only one direct superclass (single. In the absence of any other explicit superclass, every class is. Object. Example: class User.
System. out. println("salary"). Employee extends User. String specialization. Manager extends User. String department. String[] args) {.
Employee e. 1=new Employee(). Candid". e. 1. ph=1. Java". Manager m. Manager(). m. 1. name="java". HR". System. out. System. out. println(e.

Multiple inheritance(a class cannot has more than one super. Example of multiple inheritance(not supported in java)class Vehicle.
Truck extends Vehicle, Car. In the above example class Truck tries to occur the property of. Vehicle and Car Which makes the code to fail at compilation in java. If we need the both the property of Vehicle and Car in Truck. Vehicle. class Car extends Vehicle.
Vehicle. class Truck extends Car. Default super class in Java. Every class in java by defaults extends the class Object from. Example: class A. B extends A. Here B is the subclass of A, and A is the subclass of Object.
