Introduction to Class

Class:
class is a real world entity.
class contains its own data members and function members.
class is a data type, we can create a variable of a class type.
class is a instance of variables.
class is a logical construct.

syntax:

class class_name

{

access specifier:

datamembers declaratrions;

function member declaarations;

class body;

} object list;

The above syntax is for c++

for java the syntax is as follows:

syntax:

class class_name

{

access specifier:

datamembers declaratrions;

function member declaarations;

class body;

}

the syntax diffecence between c++ and java is semicolon(;) is not expected at the end of the class, while in c++ it is expected. Because in c++ the structure of the class is similar to that of 'Structres'. Here 'class' is a keyword.

Example in java:

class Student

{

char name[30];

int reg_no;

void get_details;

void display_details;

}
