Overloading

Hello world ! In this post we are going to know about overloading. When several functions are specified for a single function name in the same scope,the function name is said to be overloaded.     Java has achieved Oops concept  " polymorphic" by implementing "overloading" concept "Same name different work " Java allows function to have the same name ,distinguish by them by their :     1. their number of arguments          or      2.Type of arguments . for example: class Number { static float divide (int a , int b)          {          .....          .....          }  static float divide (float x, float y)              {              ....             ....   ...

Abstract class

Today i am going to describe about abstract and concrete class. Concrete class: The class for which object is required are known as concrete classes like JTextfield,JComboBox etc. Abstract Class: The classes for which it is not essential to declare objects to use them are know as abstract classes like JOptionPane Abstract classes are normally used as a base class in inheritance for          which no direct object required to created.Also abstract class are used for defining generic methods where there is no requirement of storing result. A abstract class contains at least one abstract method. The super class set up as an abstract class does not allow objects of its prototypes to be created. In this case only object of the subclass are used. Remembering Point: Notic  that the JOptionPane  Class which is an abstract class has no data members an so it wil...

Static keyword

Static keyword Static members are those that belong to a class as a whole and not to a particular instance (object). A static member is initialized when the class is loaded. Similarly ,A  class can have static methods,static  variables and static methods are collectively called as "static members" Static members in a class can be accessed either by using the class name or by using the object reference,but instance members can only be accessed via object references. The static can be:           variable (also known as class variable)           method (also known as class method)           block           nested class For detailed description and examples ,i am  here sharing power point presentation with you , pls download it from given link: static keyword_ppt

this keyword in java

this keyword this, "Reference variable that refers to the current object". Usage of this keyword this keyword can be used to refer current class instance variable this() can be used to invoke current class constructor.
