Class

 In all Programming Language, We create variable of built in data
types like int a;. This statement declares a variable ‘a’ of data types
‘int’ which means that ‘a’ can hold any integer data.

 Similarly we can create a variable of user defined data types like
Student s;. Here, ‘Student’ is a user defined data type and ‘s’ is
variable of that.

 In order to create a user, define data type, java provides that concept
of class. A class is a blueprint/template from which individual object
and created.

 A class consist of data and methods. A class is a collection of objects
of similar type of object. Classes are user defined data type. Once has
been defined, we can create any number of object belonging to that
class.

• For Example :

class person

{

string name; int age;

void accept (String n, int a)

{

name=n;

age=a;

}

void display()

{

system.out.print1n(“Name=’+name);

system.out.print1n(“Age=’+age);

}

}
