GOF Design pattern with Java & Real World Examples

What are design patterns? 

So basically these are just collection of best practices to solve recurring problem by different kind of class arrangement. These arrangement could be based on creation of object or structural basis or on basis of required behavior.




Creational Design Pattern
Prototype Designpattern we will like to use this designpattern whenever creation of initial object & setting required default values is costly. So we just create 1 object & later on whenever more objects required we can provide initial object by just cloning of given object.Java Example is java.lang.Object#clone()
Builder DesignPattern When we jave object structure are complex and complicated we would go for this. we will be separating object creation from internal representation. With help of some simple interface we would create complicated Object.
Singleton When we need one instance per JVM. Example : Java Run time environment Java.lang.System.  java.lang.StringBuilder, Spring Beans are singleton …
