An adapter helps two incompatible interfaces to work together. This is the real world definition for an adapter. Interfaces may be incompatible but the inner functionality should suit the need. The Adapter design pattern allows otherwise incompatible classes to work together by converting the interface of one class into an interface expected by the clients.
Structure
There are two types of adapter patterns:
Object Adapter pattern
In this type of adapter pattern, the adapter contains an instance of the class it wraps. In this situation, the adapter makes calls to the instance of the wrapped object.
Class Adapter pattern
This type of adapter uses multiple polymorphic interfaces implementing or inheriting both the interface that is expected and the interface that is pre-existing. It is typical for the expected interface to be created as a pure interface class, especially in languages such as Java (before jdk 1.8) that do not support multiple inheritance of classes.
In this video we will learn about a wrapper class.
A wrapper and a proxy class are both structural design patterns, but they serve different purposes and have different characteristics:
Few Points About Wrapper Class:
* A wrapper class, as the name suggests, wraps or encapsulates another object and provides an alternative interface or behavior to it.
* The primary purpose of a wrapper class is to add functionality to an object without modifying its interface. It allows you to extend or modify the behavior of the wrapped object.
* Wrapper classes are often used for adding logging, caching, or additional functionality to existing classes.
* A wrapper class typically implements the same interface as the wrapped object, providing a transparent layer around it.
* Clients interact with the ...

PInvoke, Wrapper Classes and the Adapter Pattern in C#
PInvoke (sometimes stylized as P/Invoke) allows managed C# code to talk to native libraries in Windows, MacOS and Linux.
It's usually best to encase PInvoke calls in to native DLLs in their own adapter that is in turn encased in a friendly .NET wrapper. This prevents users from dealing with the intricacies and headaches of PInvoke.
This is a classic use of the Adapter Design Pattern, which allows two non-compatible types to interact with each other.

In this lecture we are discussing about wrapper class:
if you want to store integer value you store in int
java provide primitive data type
thats why java is 99.9 % object oriented programming
primitive data types helps us to improve the performance
but certain feature are work only when we work with objects
for collection framework -- we need non primitive type data as input
byte -Byte
int - Integer
long -Long
char- Character
double -Double
float -Float
boolean -Boolean
Boxing:It is manual method to convert primitive type data into non-primitive type .
e.g
int num=7;
Integer num1=new Integer(8); //boxing
UnBoxing: It is manual method to convert non-primitive data type to primitive type.
e.g
int num2=num1.intValue(); //unboxing
AutoBoxing:It is automatic conversion of primitive type data into non-primitive data type.
int num3=5;
Integer num4=num3; //autoboxing
AutoUnBoxing:It is automatic conversion of non primitive type data into primitive data type.
int num5=num4; //autounboxing
int num=7;
how to store data as Object
Integer num1=new Integer(8); //this syntax is depreciated
Integer num1=Integer.valueOf(8); //Now we use this syntax
Integer num1=8; //autoboxing
int num2=num1.intValue();//unboxing
int num3=num1; //autounboxing
--convert string into int type using parseInt
String str="12";
int num4=Integer.parseInt(str);
--Convert number into String
String str1=Integer.toString(23); //convert number into string
