Java Hybrid Inheritance

In Java, there are different types of inheritance combined with one another. There are multiple inheritance types visible in this type of inheritance. Hybrid inheritance, for instance, is the term used to describe inheritance where two classes, A and B, extend class C while a third class, D, extends class A.
In simple word we can say that hybrid inheritance is nothing but combination of two more inheritance.

Hybrid Inheritance

Hybrid (mixture) generally refers to something that is made up of multiple elements. In Java, a hybrid inheritance is created by combining two or more different inheritance types. Utilizing hybrid inheritance primarily serves to modularize the code into clear classes. It also offers the ability to reuse code.

The following combinations can be used to create hybrid inheritance:
- Single and Multiple Inheritance using interface
- Hierarchical and Single Inheritance
- Multilevel and Hierarchical Inheritance
- Multiple and Multilevel Inheritance
Multiple and hybrid inheritance are only supported through interfaces in Java programming.

1.Single and Multiple Inheritance

The hybrid inheritance is made up of both single and multiple inheritance.

Java program with single inheritance and Multiple Inheritance

 // Java program with single inheritance  and Multiple Inheritance

import java.util.*;
    class Shape{  
        void Draw(){
            System.out.println("Drawing...");
        }  
    }  
    interface  Circle{ 
          public void CircleDraw();
    }  
    interface  SemiCircle{ 
          public void SemiCircleDraw();
    }
    class Test extends Shape implements SemiCircle,Circle {
        @Override
        public void CircleDraw() {
            System.out.println("Circle Drawing....");		
        }
        @Override
        public void SemiCircleDraw() {
            System.out.println("Semi Circle Drawing....");	
        }
        public void displayTest()  
        {  
        System.out.println("Method defined inside Test class....");  
        }  
   }
      
    class Inheritance{  
      public static void main(String args[]){  
          Test test=new Test(); 
          System.out.println("Hybrid Inheritance Implemented!");  
          test.Draw(); 
          test.CircleDraw();   
          test.SemiCircleDraw();
          test.displayTest();
      }
    }

Output:

Hybrid Inheritance Implemented!

Drawing...

Circle Drawing....

Semi Circle Drawing....

Method defined inside Test class....

2.Hierarchical and Single Inheritance

Java program with Hierarchical and Single Inheritance

 // Java program with Hierarchical and Single Inheritance

class Shape{  
    void Draw(){
        System.out.println("Drawing...");
     }  
  }  
  class Circle extends Shape{ 
     void CircleDraw(){
        System.out.println("Circle Drawing....");
     }
  }  
  class Rectangle extends Shape{ 
     void RectangleDraw(){
       System.out.println("Rectangle Drawing....");
     }
  }
  class Test extends Circle {
    public void displayTest(){  
      System.out.println("Method defined inside Test class....");  
    }  
  }  
  class Inheritance{  
    public static void main(String args[]){  
        Test test=new Test(); 
        System.out.println("Hybrid Inheritance Implemented Using Hierarchical and Single Inheritance");  
        test.Draw(); 
        test.CircleDraw();
  //      test.RectangleDraw()  // C.T Error
        test.displayTest();
    }
  }

Output:

Hybrid Inheritance Implemented Using Hierarchical and Single Inheritance

Drawing...

Circle Drawing....

Method defined inside Test class....

3.Multilevel and Hierarchical Inheritance

Java Program Using Multilevel and Hierarchical Inheritance

 // Java program  using Multilevel and Hierarchical Inheritance

class GrandFather{     //parent class 
	public void DisplayGrandpa(){    
        System.out.println("He is grandfather.");    
       }    
   }      
   class Father extends GrandFather    {    
       public void DisplayFather(){    
        System.out.println("He is father.");    
       }    
   }    
   class Son extends Father{    
       public void DisplaySon(){    
        System.out.println("He is son.");    
       }    
   }      
   public class Daughter extends Father{    
       public void DisplayDaughter(){    
        System.out.println("She is daughter.");    
       }  
   }
   class Inheritance{
       public static void main(String args[])    
       {      
       Son son = new Son();  
       son.DisplayGrandpa();
       son.DisplayFather();
       son.DisplaySon();
   
       Daughter daughter = new Daughter();  
       daughter.DisplayGrandpa();
       daughter.DisplayFather();
       daughter.DisplayDaughter();
       } 
   }

Output:

He is grandfather.

He is father.

He is son.

He is grandfather.

He is father.

She is daughter.

4.Multiple and Multilevel Inheritance

  import java.util.*;
    class Shape{  
        void Draw(){
            System.out.println("Drawing...");
        }  
    } 
    class Circle extends Shape{ 
        void CircleDraw(){
            System.out.println("Circle Drawing....");
        }
    }  
    class SemiCircle extends Circle{ 
        void SemiCircleDraw(){
            System.out.println("Semicircle Drawing....");
        }
    }
    interface  ShapeDraw{  
        public void Draw(); 
    }  
    interface  DrawCircle extends ShapeDraw{ 
        public void CircleDraw();
    }  
    interface  DrawSemiCircle extends DrawCircle,ShapeDraw{ 
        public void SemiCircleDraw();
    }
    class Test  implements DrawSemiCircle{  
        public void CircleDraw() {
            System.out.println("Circle Drawing....");		
        }
        public void Draw() {
            System.out.println("Drawing....");	
        }
        public void SemiCircleDraw() {
            System.out.println("Semi Circle Drawing....");	
        }
    }
      
    class Inheritance{  
      public static void main(String args[]){  
          Test test=new Test(); 
          System.out.println("Hybrid Inheritance Implemented!"); 
          test.Draw();
          test.CircleDraw();
          test.SemiCircleDraw();
          SemiCircle semiCircle=new SemiCircle();
          semiCircle.Draw();
          semiCircle.CircleDraw();
