what is class in java class in java definition of class in java with example class in java with example member methods and non member methods of class in java
Class:
It is one of the distinct principle in Object Oriented Programming language Or OOP's
principles.By using class concept is always used for developing user / programmer /
custom defined data types.
principles.By using class concept is always used for developing user / programmer /
custom defined data types.
Each and every
java program must start with concept of class.
Definition:
The process of binding data
members and associated methods as single unit is
known as Class.
known as Class.
Or
The collection of data members
and methods is known as Class.
Syntax:
Class
<classname>
{
Variable declaration;
Method definition;
}
Class demo1
{
int x,y; // data members or class
variables
float a,b;// data members or class
variables
int m1()// data methods
{
--------
Return(3);
}
float m2()// data methods
{
--------
Return(8.9);
}
}; //End of
Class
End of the class by using ; or semicolon is
optionally.
Note :
When we define class ,there is no memory space is created for data
members and associated methods.
Creation of
memory for data members in class when object is created.
We discuss it
in briefly in Object
Member
methods /non member methods Of class in java
In Object
oriented programming language we have two types of methods they are
a) Member Methods
b) Non-Menmber methods
a)
Member Methods:
The member methods is one which
are available with in the scope of class and they can access data members of
class.
b)
Non-Member Methods:
The Non-Member methods is one which is not available with in the scope of
the class and they cannot access data members of class.
Hence java programming concept supports only the concept of member method
but the concept of non-member methods.
