Learn Java

Java is one of the most well-known object-oriented programming languages ever. Immensely versatile with numerous applications and active community support, Java is an essential skill set for any aspiring programmer. In addition, major businesses like Spotify, Netflix, & Google use Java in their tech stack, which tells a lot about the prominence and popularity of the language. 

Its significance is probably why mastering Java is fraught with challenges. And while Java assignments help you will learn things faster, specific programs and development projects can confound even the most seasoned coders. To master Java, learners must expand their horizons and look for better ways to learn more holistically. In this article, we take you through some excellent Java tutorials for both beginners and advanced coders.

Well, that’s enough talk! Let’s begin.

Specialization Course in Object Oriented Programming With Java

Once you have a hold of Java fundamentals, this course will take you further. Perfect for aspirants to become a master of OOP, this course is best suited for learners with some programming experience. If you have some intermediate coding knowledge in C, C++, Python or JavaScript, you will have a tremendous start when you begin. 

This course from Coursera takes a quick look at the basics before dwelling on advanced ideas. You will learn how to solve complex problems using object-oriented design using Java. You get to work with two popular integrated development environments (BlueJ and Eclipse), learn how to design GUIs and even design programs that can handle big data. 

If you do not want to learn through online courses and instead try to tackle Java on your own, below is a simple but complete roadmap.

An Excellent Roadmap For Java Mastery 

Before you get down & dirty, know that you will have to put in the hard work and stay consistent & persistent throughout. Self-motivation is vital; practice coding every day and follow the following roadmap 🡪 

  1. Core Java

Focus on major topics like: 

  • Data Types & Variables 
  • Operators & Expressions
  • Classes, Objects, OOP concepts, & their applications.
  • String Class
  • Conditional Statements & Iterations
  • Multithreading
  • Data Structures & Collections Framework 
  • Streaming I/O 
  • The features & Java SE 18
  1. Advanced Java 

Once you have mastered Core Java, it is time to dive into the advanced aspects. Here are the vital advanced concepts to master.

  • The features of Java EE 8
  • Developmental Frameworks such as Spring, Spring Boot, Struts, Hibernate, etc.
  • The Client-Server architecture using JEE
  • Web & Application Servers such as Apache Tomcat, Glassfish, etc. 
  • Big data and analytics platforms and techs such as Hadoop & Spark
  • Software Design Patterns
  • The Java Virtual Machine 
  • Servlets 
  • Concurrent Programming 
  • Java Database Connectivity with SQL, PostgreSQL, and NoSQL
  • Git and GitHub
  • API Programming with Java
  • Java I/O and Concurrency
  • Java Servlets and Servlet Pages
  • The Java Scripting API

Build solid foundations in Core Java before moving on to advanced concepts. Work with your friends and peers while tackling challenging & extensive concepts. And, look for professional Java assignment help if things get too troublesome. 

  1. The IDEs

Java IDEs are critical for coding. There are numerous development environments, each with features, quirks, and applications. To become a complete Java coder, try to get a good grip on the following IDEs: 

  • IntelliJ
  • Eclipse
  • Visual Studio Code
  1. Learn More Use Build Tools

Build tools help automate the software development process from the source code level. Java has some great build tools dedicated to it, which every aspiring Java developer must master. Here are four of the best build tools in 2022:

  • Apache
  • Maven
  • Gradle 
  • Jenkins 
  1. Databases and Java

Databases are central to all web applications. It would be best if you learned how to integrate your web apps in Java with different kinds of databases. And for that, you need to develop clear-cut ideas about the following database systems:

  • Fundamental and Advanced SQL Concepts
  • NoSQL and MongoDB
  • Object-Relational Mapping Framework (Java Persistence API, Hibernate, Spring Data JPA< etc.)
  1. Software Testing

Testing is a crucial phase in the software development life cycle. If you want to minimize errors & boost the efficiency of your applications, then you need to know the following:

Code debugging, unit testing, functional & non-functional testing, black-box testing, integration testing, gorilla testing, grey box testing, and the like.

  1. Advanced Software Development Aspects

Modern software development has undergone rapid changes in the past two decades. Cost-effective cloud computing, containers, DevOps, etc., have substantially simplified and sped up the build process.

Once you have a firm grip on the entirety of Java, you should start developing skills & know-how essential for modern web development. Learn about: 

  • Cloud Native Technologies 🡪 Cloud computing has changed how applications are designed, developed, and operated. Make it a point to understand different kinds of cloud architecture such as public, private, & hybrid clouds and how to build agile, resilient & scalable applications with modular, loosely-coupled components. 
  • Serverless Architecture 🡪  Serverless architectures allow businesses to run apps and services without worrying about infrastructure. As-a-service products and the advent of cloud computing led to the proliferation of serverless architectures, making them a crucial aspect of modern software engineering. 
  • Microservices & Containers 🡪 A unique development architectural style, the microservices design focuses on a modular approach. Every component in a service is a self-contained, independent entity that interacts with other microservices to deliver a specific outcome. 

Containers are a great example of microservices & prominent ways to build one. They help developers focus on developing applications without worrying about dependencies. Modern cloud-native solutions are generally designed with microservices-based architecture. 

A container is a type of software that allows developers to package code and all its dependencies to ensure that the application runs optimally.  

If you are looking forward to a career in software development in Java, you will have to focus on the above aspects and develop clear-cut ideas about software engineering practices. So read more, cod more, enroll in online courses, and avail of professional Java assignment help for those challenging assignments.
