Inheritance:-Inheritance is the process by which one object acquires the properties of another object.

There are 3 types of inheritance in java

 When class uses another class then we use extends or when class uses inheritance of another class then we use implements.

class Inher{

void mobile(){

System.out.println("Samsung");

}

}

class Main extends Inher{

void laptop(){

System.out.println("Acer");

}

public static void main(String args[]){

Main m=new Main();

m.laptop();

m.mobile();

}

}
