lecture second

method overloading 

1.  return type should be same

2.  can't create two functions with same parameters in class

class A

f

void add (int a, int b);

void add (int a, string b, int c);

A obj =new A(); 

access modifier

1.public ( access in all area)

2. private (only access in class)

  

final keyword-avoid inheritance

encapsulation

In class method and variables in a single unit

note;

1. declare the class variables in private

2. declare the class methods in public

example 

private int a;

public set (int a)

this a=a
