Creational Patterns : Prototype


Properties:
-          When cost of creating an object from scracth is high it might be good idea to create it by cloning an existing object.
-          Identified by a super class declaring a clone method and implemented clone method inside class.

Implementation:
-          Class extends a super class which declares a clone method.
-          Clone method is implemented to create a copy of the object.
Java Standard Library Implementations:
-          Any class implementing  java.lang.Cloneable

Example Usage:
// simply person clone is invoked
Person newPerson = (Person)person.clone();

Obfuscating Spring Boot Projects Using Maven Proguard Plugin

Introduction Obfuscation is the act of reorganizing bytecode such that it becomes hard to decompile. Many developers rely on obfuscation to save their sensitive code from undesired eyes. Publishing jars without obfuscation may hinder competitiveness because rivals may take advantage of easily decompilable nature of java binaries. Objective Spring Boot applications make use of public interfaces, annotations which makes applications harder to obfuscate. Additionally, maven Spring Boot plugin creates a fat jar which contains all dependent jars. It is not viable to obfuscate the whole fat jar. Thus obfuscating Spring Boot applications is different than obfuscating regular java applications and requires a suitable strategy. Audience Those who use Spring Boot and Maven and wish to obfuscate their application using Proguard are the target audience for this article. Sample Application As the sample application, I will use elastic search synch application from my G...

Hadoop Installation Document - Standalone Mode

This document shows my experience on following apache document titled “Hadoop:Setting up a Single Node Cluster”[1] which is for Hadoop version 3.0.0-Alpha2 [2]. A. Prepare the guest environment Install VirtualBox. Create a virtual 64 bit Linux machine. Name it “ubuntul_hadoop_master”. Give it 500MB memory. Create a VMDK disc which is dynamically allocated up to 30GB. In network settings in first tab you should see Adapter 1 enabled and attached to “NAT”. In second table enable adapter 2 and attach to “Host Only Adaptor”. First adapter is required for internet connection. Second one is required for letting outside connect to a guest service. In storage settings, attach a Linux iso file to IDE channel. Use any distribution you like. Because of small installation size, I choose minimal Ubuntu iso [1]. In package selection menu, I only left standard packages selected.  Login to system.  Setup JDK. $ sudo apt-get install openjdk-8-jdk Install ssh and pdsh, if...

Behavioral Patterns : Chain of Responsibilities

Properties: -            Lets a request to be passed sequentially to a set of handlers. -            Each handler decides wheter to handle the request or pass it to next handler. Implementation: -            Handler  interface declares operations to handle requests. -            ConcreteHandler  decides wheter to handle the request or pass it to next handler. Java Standard Library Implementations: -            javax.servlet.Filter#doFilter(ServletRequest request,ServletResponse response,FilterChain chain) -            java.util.logging.Logger#log(Level,String) Example Usage: public   class  Logger  {      public ...
