Types Of Inheritance

1)Single Inheritance

2)Multilevel Inheritance

3)Hierarchical Inheritance

Single Inheritance

• Things in one class are used in another class.
  
  
• Here class B has Inherited from class A.
• class A  operates as a "Superclass" and class B as a "Subclass". 
  
  
• class B can use the "Variables" and "Methods" of class A 
  
  
  

  Multilevel Inheritance

• There are Three classes here.
  
  
• class A  works as a"Superclass" and class B and class C  as a "Subclass". 
  
  
• And when class C  works as a "Subclass", class B works as a "Superclass".
  
  
• class B can use  the"Variables" and "Methods" of class A
  
  
• class C can use the "Variables" and "Methods" of class B
  
  
• class C can use the "Variables" and "Methods" of class A
  (Because class B is Inherited from class A)

Hierachicle Inheritance

•  class A  works as a "Superclass" and class B and class C  as a "Subclass". 
  
  
•  class B can use the "Variables" and "Methods" of class A
  
  
• class C can use the "Variables" and "Methods" of class A
