Here is my list of some practical tips for any Oracle Java certification aspirants. These tips are based on my own experience and what I have heard from many readers on my blog and all over internet

Write Code Daily
One of the best way to prepare for Java certification is to write code daily. Try to code the questions and examples given in the book and see if answer matches with the output of the program. This will not only develop software personality But also improving your  code reading ability  which is very important to solve Java Puzzles from actual exams.

You can also experiment with your code to see how one small change can totally change the output of the program. If you just do exercise without coding, you That will not learn much. That's like students mug concepts in schools. Don't do that, it may not result in the desired outcome if there is even the slightest change in the actual exam.


Solve Practice questions from Book
You should first try to solve the practice questions, quizzes, fill in the blanks and other exercises given in your book and always solve them honestly ie know everything about them. For example, once you are done with one question, you should know what is Expected, why the correct answer is right and why all other answers are incorrect. If you solve questions like this in your learning phase, you will learn a lot more concepts by just solving a single question. This is IMHO, the right way to use The exercise and practice questions.


Participate in CodeRanch Forum
You need an environment to boost your preparation and there is no better place to get that environment than  http://coderanch.com/. It was earlier known as Javaranch forum and it is certainly the best place to hang out if you are preparing for Java certifications.

The CodeRanch form has got the biggest and most active community of Java developers preparing for various Java certifications like OCAJP, OCPJP, Java Web Developer Exam, Java Web Service exam, and even Java Architect level exam. Even several famous book authors like Kathy Sierra and Mala Gupta hangs around there.

By participating on this forum, you will not only be up-to-date with any Change happening on the syllabus but also other news about the exam. They even have dedicated forum for different Oracle Java certification eg separate forum for  OCAJP  and  OCPJP  exams are the best place if you are preparing for them.

You can not only use this forum to get help but also help others revise your knowledge, this will also help you to clear out any misconception you might have. By hanging out, you will also learn about several  free mock exam and other Java certification Resources by various participants.

Do Mock Exams
Java Certification preparing is virtually incomplete without taking a couple of mock exams. They are the most important part of your preparation because by giving mock exam in the actual exam like environments you gauge your speed, accuracy, and endurance. You also get familiar with the actual pattern and how to deal with both touch and easy questions.

I also suggest to only use quality mock exams from Whizlabs or Java8Certification and spend a lot of time on analyzing each question, even wrong choices to figure out why they are wrong. You can use them as your final learning tool.

Btw, Don't rush through all exams in quick time. Given one of them, record your score to gauge speed and accuracy and go through all the questions again, particularly the ones which you did wrong. Don't give next exam, unless you are comfortable with the topics you haven't done well on the first try. If you are doing it right then you will gradually see your speed and accuracy increasing.

The traditional way to run a Spring web application on a remote server is to package it into a war file and deploy that file into a servlet container.

Although this method has served us well in the past, managing multiple servlet containers has always been a bit cumbersome.

Spring Boot provides one solution to this problem. It allows us to package our web application into an executable jar file that uses an embedded servlet container.

 requirements:

• Our Spring Boot application must use Thymeleaf as a templating engine.
• Our Spring Boot application must provide us a way to monitor it.
• Our Gradle project must have separate source and resource directories for unit and integration tests.

REST API is today's requirements for Mobile Apps, Web Application or Desktop Application that need to connect with Database. That's why we need to create a step by step tutorial of building Java REST API server using Spring Boot and MongoDB. The data store in MongoDB server And accessible everywhere via Java REST API. Previously, we have to create REST API in different technology and framework using Grails and Node.js. Now, we are using Spring Boot for it. After all, you can compare which technology or framework that fits Your needs.

1. Generate a New Spring Boot Gradle Project

We assume that you have installed JDK 8, Gradle and IDE (Netbeans, Eclipse, STS or IntellijIdea). Next, we will create a new Spring Boot Gradle project using Spring Initializer. Just go to Spring Initializr web-based Spring project generator then fill The required frameworks and libraries.

After filling all fields, click Generate Project. It will automatically download the zipped project. Next, extract the zipped project to your java projects folder. On the project folder root, you will find `build.gradle` file for register dependencies, initially it Looks like this.

Buildscript { 
     Ext { 
         springBootVersion = '1.5.7.RELEASE' 
     } 
     Repositories { 
         mavenCentral() 
     } 
     Dependencies { 
         Classpath( "org.springframework.boot:spring-boot-gradle-plugin: ${springBootVersion} " ) 
     } 
 } 
 
 Apply plugin: 'java' 
 apply plugin: 'eclipse' 
 apply plugin: 'org.springframework.boot'
  
 Group = 'com.spring' 
 version = '0.0.1-SNAPSHOT' 
 source Compatibility = 1.8 
 
 Repositories { 
     mavenCentral() 
 }
 
 
 Dependencies { 
     Compile( 'org.springframework.boot:spring-boot-starter-data-mongodb' ) Compile 
     ( 'org.springframework.boot:spring-boot-starter-web' )
      test Compile( 'org.springframework.boot: Spring-boot-starter-test' ) 
 }
