Best Java Full Stack Learning Path | Complete Roadmap

The Ultimate Guide to Becoming a Java Full Stack Developer

Java Full Stack Development is a highly sought-after skill, requiring expertise in both front-end and back-end technologies. This guide provides a structured roadmap to help you become a proficient Java Full Stack Developer.

Master Core Java

Before diving into full-stack development, you must have a solid foundation in Core Java. Key topics include syntax, data types, object-oriented programming (OOP), exception handling, collections framework, multithreading, and Java 8+ features such as lambda expressions and streams API. Understanding these concepts will help you write efficient and scalable Java applications.

Learn Front-End Development

A Full Stack Developer must be proficient in front-end technologies to build interactive and user-friendly applications. Start by learning HTML, CSS, and JavaScript, which form the foundation of web development. Then, move on to modern front-end frameworks like React.js and Angular to build dynamic and responsive web applications. Learning TypeScript is also beneficial, especially for Angular development. Platforms like FreeCodeCamp, MDN Web Docs, and YouTube tutorials provide excellent resources to master front-end technologies.

Backend Development with Java & Spring Boot

Java is widely used for back-end development, and Spring Boot is the go-to framework for building enterprise-level applications. Key concepts include JDBC (Java Database Connectivity), Spring MVC (Model-View-Controller), RESTful API development, and Spring Data JPA for database operations. Additionally, learning Spring Security for authentication and authorization, and understanding microservices architecture for scalable applications is essential.

Database Management (SQL & NoSQL)

Databases are a crucial part of any full-stack application. A Full Stack Developer should be proficient in SQL databases (MySQL, PostgreSQL, Oracle) and NoSQL databases (MongoDB, Firebase, Cassandra). Important topics include database normalization, writing SQL queries (JOIN, GROUP BY, INDEXING), and using ORM tools like Hibernate for efficient data handling.

Version Control & Deployment

Version control and deployment skills are essential for collaborative development and efficient software deployment. Learn Git and GitHub to manage your code, collaborate with teams, and track changes. Additionally, understanding containerization with Docker and Kubernetes, CI/CD tools like Jenkins and GitHub Actions, and cloud platforms like AWS, Azure, and Google Cloud will help you deploy applications effectively. Resources like GitHub Docs, DevOps courses, and online tutorials will help you master these tools.

Build Real-World Projects

The best way to reinforce your skills is by building real-world projects. Some project ideas include: ✔ E-commerce Website (Spring Boot + React/Angular) ✔ Blog Application (User Authentication, CRUD Operations) ✔ Library Management System (Spring Boot + MySQL) ✔ Online Book Store (Hibernate ORM + REST API)

We provide industry-driven master’s programs designed to help you excel in high-demand fields.

Start learning today, take one step at a time, and stay updated with the latest trends in Java Full Stack Development.

Hey there! I love all the turn ons and turn offs mod but I want to replace the plantsim icon with the supernatural fan trait icon from ts3. I know how to change texture image in simpe, but the "jpg/tga/png image" I can only export the icon not import my own. Do you know any tutorial to do that? I'm sorry for my awkward english I'm still learning, but reading is easier

Hello! You should right-click on it (not the actual image itself, but in the resource list instead of left-clicking on jpa/tga/png Image to make the image appear in the picture viewer right-click it) and select “replace”. Then it’ll let you find the image on your computer and replace it :)

DISH2019- My first of many

OUR TEAM...

From left to right Ric Sapasap, Aviv Guese, Gio Canoy, Tyler Venzon, Brandon Partosa. My sleep deprived team.

Our team is composed of three blockchain trainees and two senior java developers from our company. We are the pioneer batch of trainees to undergo training to become blockchain developers but as this technology is new even to the senior developers at our company, our understanding of this technology is still superficial.

We are only halfway through our training and we are  working our way up from Java to Blockchain to ease us into the new technology. Little did we know that we’d dive right into #DISH2019, totally unprepared and with only partial knowledge about the craft.

GETTING READY...

When we learned that we were going to take part in the hackathon, the whole team researched and tried to learn about everything as much as we can absorb, we also looked into the possible use cases that would fit into #DISH2019’s theme: “Inclusive Prosperity”

During our research, we had a hard time looking for use cases because the theme was vague to us back then, but at the same time, our research helped us a lot to grow as developers.

Joining the hackathon, we are not expecting anything else other than learning and enhancing our understanding about this new tech. Win or lose, we know that we will be going home with something worth more than what we came for.

As for preparation, our goal was to familiarize ourselves with the concept of blockchain as much as we can. Most of the content we studied came from various Youtube talks and tutorials, a Udemy course, Cryptozombies, and the documentations for Ethereum, Ganache, etc. We also attended a crash course on smart contracts using Ethereum. 

THE EVENT...

During the event all of us are nervous but excited at the same time SINCE THIS IS OUR FIRST TIME JOINING A HACKATHON! Honestly, we are not scared to lose. For us winning will be a miracle. All we wanted was to learn more about our supposed specialisation and build our knowledge on a new technology that only few in the world know so much about. Fortunately, awesome people from Blockdevs Asia were there to help us out.

Prior to the coding session of the Hackathon, the event had these “Breakout” sessions where representatives of different blockchain platforms allow interested groups to ask questions about the platform and know more about the features each platform can offer.

Among the platforms presented, our team leaned towards IOST. We were curious about IOST since it was new and had features that fit better with the ideas that we had. It was then that we found ourselves in a conference room for a quick introduction to IOST with the CTO himself, Terrence Wang.

After the talks about the different blockchain platforms, we started finalising our topic. It was hard for us to decide as all of our ideas were solid and well thought of. The only question is the do-ability in that specific amount of time. From sperm bank, to organ donation, to scholarships and to many more, we arrived to the conclusion that we were going to make a quiz game.

THE IDEA…

The goal of the app is for the clients to sponsor trivial games that aims to promote ideas and awareness about different issues concerning the likes of the environment, voting, or health.

Sponsors (clients) will fund the quiz game which will serve as the prize pool and payment for the player’s gas costs. A percentage of which will be taken as service fee.

STARTING THE APP...

We divided our DApp into three layers, the front end (where we used Angular-Material), the backend (where we used Java as that is what most of us know) where we created our Rest Controllers and Quiz Controllers, and the smart contracts itself (Javascript).

We modelled our DApp. We planned to use Firebase as a way to store our questions but we had a hard time running the test net. As there is not much time to dilly-dally , I jumped to the old-fashioned MySql. So, in our backend, we have to set up the my-sql connector. Luckily, there is JPA to ease our lives and made the code cleaner since I avoided the use for the DML of SQL. 

>>>INSERT CHOICE REPOSITORY HERE

** **

For our front-end, we made the UI using Angular-material.

>>>INSERT UI CODE HERE

I tried setting up the node locally. Again relying on the documentation with some panicking as there are some errors involved. (sorry for the lack of documentation for it).

With a lot of discussion in the team sharing what we can understand from the documentations and the available materials in the web, we made our smart contract. 

>>>INSERT  QUIZ CONTRACT

The quiz contract is for the sponsors to create the quiz. For our prototype, we are requiring the sponsors to pay 5 iost as a quiz fee plus the prize pool.  

Elimination:

As stated earlier, players that gets the correct answer will be appended to the blockchain, but not all are eligible for the prize as we want to filter the players, therefore the need for elimination. Let’s say players A,B,C, D and E are playing the quiz and they all answered the quiz correctly. They will now be added to the list of winners.

And then in the next item D got it wrong, and was eliminated. Players A,B, C and E will now be added. And for the next item D (who got the previous item wrong) answered it correctly this time. Sadly he is not in the latest list of surviving players which means he is not eligible to be appended. The elimination goes on until the quiz is finished and the reward is distributed.

We have a lot of ideas on how are we going to improve our DApp. The hackathon is a fun way to learn a lot of things and meet people. From what I learn as a firsttimer:

DO NOT BE SCARED TO TRY THINGS

DO NOT PANIC

DON’T BE SHY TO APPROACH THE MENTORS

DON’T BE AFRAID TO SOCIALIZE

DON’T  BE AFRAID TO LOSE

And of course, we would like to thank our awesome mentors, Caspar Oostendorp and Amadeo Brands, who guided us during development. They made working with a technology in infancy much more bearable and learnable since there was almost little to no documentation on how IOST worked. We would also like to extend our gratitude to Roy Selbach and Mark Vernon who helped us fine-tune the business aspect of our prototype by sharing their insights and positivity with our product. And to Miss Tracy Li who invited us to join this Hackathon.

MySQL Driver: required to connect with MySQL database.

It eliminates the need of writing queries as you do with JDBC. The Spring Data JPA is an abstraction over JPA that provides utility methods for various operations on databases such as creating, deleting, and updating a record. JPA (Java Persistence API) is a Java Specification that maps Java objects to database entities, also known as ORM (Object Relational Mapping).

Spring Data JPA: required to access the data from the database.

Spring Web: required for building RESTful web applications.

Hence, you can choose the same Java version to follow along.Īdd the following Dependencies to the project:

Description - provide a description about the project.Ĭhoose “Jar” as the Packaging type as the application will run in the embedded Tomcat server provided by Spring Boot.

You can keep it the same as the artifact name, "employee".

Name - this is the display name for your application which Spring Boot will use when creating the entry point for the project.

Since you are creating an application for accessing and manipulating employee details, you can provide “employee”.

Artifact - this is the name of your project.

This follows the Java package naming convention.

Group - this is the base package name indicating the organization or group that is creating the project.

Include the following identifiers under Project Metadata for your project: Note that this tutorial is built with Spring Boot version 2.5.6, so select the same version in Spring Initializr. Under Project, choose “Maven” and then “Java” as the language. This tool provides the basic structure of a Spring Boot project for you to get started quickly. To create the Spring Boot application, you’ll use a tool called Spring Intializr.

Overall, Spring Boot makes a great choice for devs to build their applications because it provides boilerplate code with all the necessary configurations to start with the coding right away. You don't have to create and configure the beans as Spring Boot will do it for you. Beans in Spring are objects that are instantiated and managed by Spring through Spring IoC containers. If the dependency is available in your classpath, Spring Boot will auto-create the beans for it. An auto-configuration feature by Spring Boot that configures your application automatically for certain dependencies.Embedded Tomcat server to run Spring Boot applications.No requirement for complex XML configurations.A few benefits of using Spring Boot for your REST APIs include: It allows you to create REST APIs with minimal configurations. Spring Boot is a Java framework, built on top of the Spring, used for developing web applications.

During installation, create a free account when prompted.

Postman desktop application to test the APIs.

Make sure to configure Maven in Eclipse IDE. When running the installer, it will ask for the specific package to install, choose “Eclipse IDE for Java EE Developers”. You can follow the guide for detailed steps to setup MySQL with Workbench.

MySQL is the database service you’ll use to store the employee data and access in your application through REST APIs.

Java Development Kit (JDK) version 8 or newer.

Some prior knowledge of Java or a willingness to learn.

In this tutorial, you will develop REST APIs in Spring Boot to perform CRUD operations on an employee database. After developing several REST APIs using Spring Boot, I decided to write this tutorial to help beginners get started with Spring Boot. This led me to explore various frameworks such as Spring Boot. I always wanted to know how these APIs are developed so that I can create APIs myself. The server then performs the whole business logic and returns the result. I was always amazed to see how REST APIs are used in establishing communication between client and server over HTTP. I’ve been using Twilio’s REST APIs for quite some time now.
