Generalization in java with examples

By
     Generalization basic points

  •  Type/Subtype Relationship
  •  "IS A " Relationship
  •  One class has many subclasses
  •   General class can have many Special classes as  subclasses
  •  General names can be used to Address special names
  •  Top to bottom hierarchy goes towards specialization
  •  Bottom to top Hierarchy goes towards generalization


 e.g         Soap  
  Bath Soap and Washing Soap is a subclass of Soap
e.g COldDrink
  Pepsi      Team

 -Cold Drink is a general class
-Pepsi and team are special classes

 e.g    Person

 Teacher       Student
e.g            Car
    Sedan           Hatchback
Honda   Suzuki     Suzuki   Toyota
civic        Liana      Alto      vitz
....................................................\
Some Examples from Nature

 e.g.               Animal
           Mammals            Reptiles 

   Human           Cow     Snake         Croc

 Student Teacher             Cobra Python    
e.g                     Fruits
     Mango       Orange       Banana     Strawberry


Some Examples from Kitchen
e.g             Cutlery
     fork                Spoon     Knife

 Some Examples from Library

 e.g  
                    Book
      Social Science            Natural Science
.................................................
Some Examples from Computer Lab

 e.g                     Computer
       Desktop                         Laptop
   Compaq                                HP
e.g                    Printer
        Laser     Inkjet          DotMatrix

 ....................................................

 Some Examples from Car Parking

 e.g               vehicle

    Car          bike        Van      Truck

 ...............................................
Discriminator
 - Special types based on discriminator

 E.g Fruit (color)
  
Red    Yellow    Green


e.g Person (religion)

         Muslims   Chris   Hindu   Jew

              Person  (Designation)

 law   Student  teacher  Mula  Dako thief  Doctor poond
e.g                   Student (Cgpa)

            above3              below3
e.g                   Student (grade)

            AGrade                      Bgrade         

 e.g Person(economically)

 lowerMiddle      Middle    UpperMiddle  Upper
Types Of Generalization

  1.  Inheritance
  2.   Realization

Composition in Java with code examples

By
Composition  "Have a " Relationship  OR  "Must have" relationship                    between two or more classes. Container class contains component's class object For example a  Car is composed of engine and body. Where Car is a container class and both Engine and Body are components class.  Life Time Issue in Composition Life time of component objects depends on container class If Container object destroyed, component objects will be also destroyed Car Example  There is a composition relationship between car's body and engine. Car must have Engine and body If Car destroyed, both Engine and Body will be destroyed class  Engine {   Engine  () {    System.out.println ( "Engine created" ) ; }   void  start () {    System.out.println ( "Engine Start" ) ;   } } class  Body {   Body  () { System.out.println ( "Body created" ) ; }   void  type () {    System.out.println ( "Sa

Aggregation in java with example codes

By
What is aggregation?   "Have a" or "May have" relationship  Aggregation is special type of association  Life time of Component object is independent from its  container object E.g A school has one student class  Student  { String name; Student  () { name= null ;  } Student  ( String n ) { name=n;  } void  setName ( String n ) { name=n; } String getName () {  return  name; } } class  School { Student  st; School  (  ) {  st= null ; } School  ( Student s ){ st=s; } void  studentName (){    System.out.println ( st.getName ()) ; } } class  Post { public static  void  main  ( String a []){ Student st= new  Student ( "Imran" ) ; School s=  new  School ( st ) ; s.studentName () ; } } Output Hello Problem : A Car must has Engine and body.           A Car may or may not has Ac Adding Ac as an Aggregate object in car class  Engine { void  start () { System.out.println ( &
