Object Oriented Programming in JAVA – Inheritance 

What is Inheritance?

• The main purpose of the inheritance is code extensibility whenever we are extending automatically the code is reused.
• In inheritance one class giving the properties and behavior and another class is taking the properties and behavior.
• Inheritance is also known as is-a relationship means two classes are belongs to the same hierarchy.
• By using extends keyword we are achieving inheritance concept.
• In the inheritance the person who is giving the properties is called parent the person who is taking the properties is called child.
• To reduce length of the code and redundancy of the code sun peoples introducing inheritance concept.

Types of Inheritance

Another Inheritance

class ParentClass {
      public void P1()
      {
	System.out.println("Parent Class Method is called");
      }
}
 class childclass extends ParentClass{
	 public void C1()
	 {
	 	System.out.println("Child Class Method is called");
	 }
	 public void C2()
	 {
	 	System.out.println("Child Class Another Method is called");
	 }
}
//For Multilevel Inheritance
class superchildclass extends childclass
 {
	 public void SC1()
	 {
	 	System.out.println("Super Child Class Method is called");
	 }
 }

public class InheritanceEx {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		childclass cobj=new childclass();
		cobj.C1();
		cobj.C2();
		cobj.P1();
		ParentClass pobj=new ParentClass();
		pobj.P1();
                 //For Multilevel Inheritance
                superchildclass scobj=new superchildclass();
                scobj.SC1();
	}
