With over 1.7 billion websites worldwide and 4.54 billion people using the internet actively, the need for heightened customer experience is on the rise. This is one of the major reasons why professionals who are adept at handling both the client-side and server-side interfaces of an application/website have become more important than ever. The Full Stack developer role is the No.1 position to be filled in 2020 according to 38% of hiring managers. This is closely followed by the role of a back-end developer.
Full Stack Java Developer is the in-demand for the Software IT Industry. Today’s tech companies need developers who just not code but also good solution architects, developers, testers, and designers. Full Stack Java Developer is one such end-to-end developer who takes care of end-to-end product development with expertise in Java and other related technologies.
What is Java?
What is Full- Stack Developer?
A full-stack developer is a professional who can handle back-end development tasks such as databases, servers, and systems engineering, as well as front-end web development and UI work. Depending on the project, your work might include a mobile stack, a Web stack, or a native application stack.
What is Java Full- Stack Developer?
A java full stack web developer is a developer with extensive knowledge and expertise in full-stack tools and frameworks that works with java.
The java suite of technologies includes working with servlets, core java, REST API and more tools that make the building of web apps easy. It’s a great choice of career and the easiest way to become a developer is to take a full stack web developer offline at an institute. It’s great for your resume.
There are primarily three layers in software application architecture:
A Full Stack Java Developer takes care of all the three layers in software development.
This is where the data is stored and retrieved for the product. Examples of such systems are MySQL, Oracle, PostgreSQL, Microsoft SQL Server, MongoDB, etc. Data is accessed by the application layer via API calls.
The application layer contains the functional business logic which drives an applications core capabilities. It’s often written in Java, .NET, C#, Python, C++, etc.
A Full stack developer is one who uses a stack of technologies required to build and run a complete (having all layers) application.
Full-stack Java developers usually refer to developers who can:
* Comfortably work with Unix or Linux operating system.
* Understand and work with the intricacies of relational database (E.g.: MySQL, Postgres, etc.) and one non-relational database (E.g.: MongoDB, Cassandra, etc.)
* Know which web framework (pertaining to a language they are programming in- Servlets, JSP, JSF, SpringMVC, Struts, Play Framework, Ratpack, etc.)
* Use DI frameworks like Spring, Guice, etc and ORM frameworks like Hibernate.
* Write and set up various testing strategies (unit tests, integration test, etc.) using tools like JUnit, Selenium, Mockito, etc.
* Understand associated infrastructure technologies for logging, caching, security, metrics, searching, queues etc. (Log4J, Ehcache, Spring security, ElasticSearch, ApacheMQ, Logstash, Kibana, Redis, etc.)
* Work with a Version Control System (VCS) like SVN, Git, Mercurial, etc.
* Understand some DevOps tools (for CI/CD) like Jenkins, GoCD, Concourse, etc.
Top 10 Skills to become a full-stack Java Developer
1 HTML/CSS – While HTML stands for Hypertext Markup Language, CSS stands for Cascading Style Sheets. HTML is used for adding web content, and CSS is a personalization tool for designing and styling a website. Both HTML and CSS determine the look and feel of a website, which ultimately plays a major role in attracting prospective customers. Full Stack Developers have to work with HTML to define the structure of web pages by using markup. They must also be proficient in CSS for effective presentation of the HTML elements. Full Stack Developers must have extensive knowledge in both of these programming languages for creating an interactive, intuitive, and engaging frontend for applications.
2 Databases and Web Storage – After concentrating on front-end and back-end, you need to focus on a data repository where you can store it for further access. You must have a clear understanding of relational databases and memory storage, and be capable of creating, understanding, and manipulating the database query.
Also, you need to understand the concepts of relational and non-relational databases. To store the data effectively, you are required to clearly understand the peculiarities of relational data, NoSQL databases, and web storage. You also need to know how to link a database and the back-end.
3 Java- The general-purpose language, that’s been around for two decades and more and is still going strong. This article is all about java and why and how to specialise as a full stack web developer. As such, this is an indispensable skill that you’ll have to learn.Java is a high-level programming language developed by Sun Microsystems. It was originally designed for developing programs for set-top boxes and handheld devices, but later became a popular choice for creating web applications. The Java syntax is similar to C++, but is strictly an object-oriented programming language.
4 Microservices- These are an architectural style that develops a single application as a set of small services. Each service runs in its own process. The services communicate with clients, and often each other, using lightweight protocols, often over messaging or HTTP.
Microservices can be thought of as a form of service-oriented architecture (one of the most critical skills for Java developers) wherein applications are built as a collection of different smaller services rather than one whole app.
5 JSP- Java Server Pages is a back-end technology to create a dynamic, platform-independent web application. It supports dynamic content and has access to the whole java API family. This is a must-learn technology.JSP technology is used to create a web application just like Servlet technology. It can be thought of as an extension to Servlet because it provides more functionality than servlet such as expression language, JSTL, etc.
A JSP page consists of HTML tags and JSP tags. The JSP pages are easier to maintain than Servlet because we can separate designing and development. It provides some additional features such as Expression Language, Custom Tags, etc.
6 Java Web-service/RestFul API- Based on representational state transfer technology for communication in web services development. It is a standard API for get, put, post and delete data. This is something you’ll end up learning if you have to code in java.Java API for RESTful Web Services (JAX-RS) is the Java API for creating REST web services. JAX-RS uses annotations to simplify the development and deployment of web services. JAX-RS is part of JDK, so you don’t need to include anything to use its annotations.
7 Hibernate- Hibernate is a Java framework that simplifies the development of Java application to interact with the database. It is an open-source, lightweight, ORM (Object Relational Mapping) tool. Hibernate implements the specifications of JPA (Java Persistence API) for data persistence. It is a popular choice in enterprise applications for performing database operations. It is a great skill to learn.
Following are the advantages of the hibernate framework:
1) Open Source and Lightweight:
Hibernate framework is open source under the LGPL license and lightweight.
2) Fast Performance:
The performance of the hibernate framework is fast because the cache is internally used in hibernate framework. There are two types of cache in hibernate framework first-level cache and second-level cache. The first level cache is enabled by default.
3) Database Independent Query:
HQL (Hibernate Query Language) is the object-oriented version of SQL. It generates the database-independent queries. So you don’t need to write database-specific queries. Before Hibernate, if the database is changed for the project, we need to change the SQL query as well that leads to the maintenance problem.
4) Automatic Table Creation:
Hibernate framework provides the facility to create the tables of the database automatically. So there is no need to create tables in the database manually.
5) Simplifies Complex Join:
Fetching data from multiple tables is easy in the hibernate framework.
6) Provides Query Statistics and Database Status:
Hibernate supports Query cache and provide statistics about query and database status.
8 DevOps- It is simply a portmanteau of software developers and IT Operations. It was first called agile operations and involves different disciplines in building, operating and evolving applications and services.
Using a DevOps model, you are bringing together your development team and your operations team, and their work is no longer in silos. These teams, and sometimes together with the security and quality assurance teams, work together to bring about the new application – from developing, to testing, to deploying, and then to operating it.
Java DevOps is simply applying DevOps practices and philosophies to Java app development. That means that compartmentalized teams are no longer needed when creating Java applications.
Some of the principles you should know to include:
Continuous integration: This practice requires developers to periodically merge the code that they have written into a central repository. After the merge, tests and automated builds are executed. This allows a team to find issues and quickly quash out bugs, improve the application’s quality and then cut the time needed to validate your apps. It also helps your team release new updates faster.
Continuous delivery: This practice requires your team to release into production all code changes after it is written and then automatically built, and tested. If continuous integration puts your code changes onto a testing environment, continuous delivery puts it into a production environment.
Infrastructure as code: This practice means that infrastructure is allocated and then managed by using code and development techniques. Cloud services can help your development and operations teams interact with infrastructure at a scale they are comfortable with. With infrastructure as code, servers and infrastructure are deployed fast, automatically patched and can easily be duplicated. Your team can also automate configuration management, and also take advantage of policy as a code, where compliance with regulatory requirements is practically ensured.
9 Spring boot- Spring Boot is a project that is built on the top of the Spring Framework. It provides an easier and faster way to set up, configure, and run both simple and web-based applications. It is a Spring module that provides the RAD (Rapid Application Development) feature to the Spring Framework. It is used to create a stand-alone Spring-based application that you can just run because it needs minimal Spring configuration. It is the spring module for rapid application development. It is known as the framework to learn to create a microservice. It is used to create a stand-alone spring-based application. It seriously improves productivity as you can now create a new Java web project in much less time and with much less work, but at the same time, it’s a bit opinionated.
We should use Spring Boot Framework because:
1.The dependency injection approach is used in Spring Boot.
2.It contains powerful database transaction management capabilities.
3.It simplifies integration with other Java frameworks like JPA/Hibernate ORM, Struts, etc.
4.It reduces the cost and development time of the application.
Along with the Spring Boot Framework, many other Spring sister projects help to build applications addressing modern business needs. There are the following Spring sister projects are as follows:
a)Spring Data: It simplifies data access from the relational and NoSQL databases.
b)Spring Batch: It provides powerful batch processing.
c)Spring Security: It is a security framework that provides robust security to applications.
d)Spring Social: It supports integration with social networking like LinkedIn.
e)Spring Integration: It is an implementation of Enterprise Integration Patterns. It facilitates integration with other enterprise applications using lightweight messaging and declarative adapters.
10 Git- Git is an open-source distributed version control system. It is designed to handle minor to major projects with high speed and efficiency. It is developed to co-ordinate the work among the developers. The version control allows us to track and work together with our team members at the same workspace. Git was created by Linus Torvalds in 2005 to develop Linux Kernel. It is also used as an important distributed version-control tool for the DevOps.Git is easy to learn and has a fast performance. It is superior to other SCM tools like Subversion, CVS, Perforce, and ClearCase.
Benefits of Git:-
Git is lightning fast technology. Each command takes only a few seconds to execute so we can save a lot of time as compared to login to a GitHub account and find out its features.
One of the most important benefits of Git is that it supports offline working. If we are facing internet connectivity issues, it will not affect our work. In Git, we can do almost everything locally. Comparatively, other CVS like SVN is limited and prefer the connection with the central repository.
One additional benefit of Git is we can Undo mistakes. Sometimes the undo can be a savior option for us. Git provides the undo option for almost everything.
4.Track the Changes
Git facilitates with some exciting features such as Diff, Log, and Status, which allows us to track changes so we can check the status, compare our files or branches.
Knowledge of Git allows Full Stack Java Developers to better collaborate and cooperate with their fellow developers/programmers who are working on the same project. Every small change in coding can be detected with git which sores every version of the code ever written.
Full Stack Developers are highly skilled experts who can handle everything related to web development. These Full Stack Java Developer skills are what distinguishes them from Frontend and Backend Developers.
There are a lot of companies that hire Full Stack Java Developers. And since a Full Stack Java Developer can manage all the product development requirements single-handedly, start-ups prefer Full Stack Java Developers.
Java is the most popular and in-demand programming language in the IT domain. Although there are other Full Stack developers with different technology stack (for example MEAN, LAMP etc), 60% of technology businesses today implements Java Full Stack. Hence the demand for Full Stack Java Developer is very high
