You’ve come to the right spot if you’re a programmer or recent graduate of computer science who wants to learn Java and is seeking for some great resources like books, tutorials, and online courses. I’ve already given some of the top Spring Framework Courses and websites to learn Java, and in this post, I’ll present some of the best Java Courses for beginners.
What is Java
Java is a high-level object-oriented programming language. It has one unique feature that sets it apart: platform independence. In other words, it may be developed once and operate on every operating system, including Windows, macOS, and Android.
It compiles to Java Bytecode, which is a step between pure written Java and machine code, as opposed to straight to machine code. A Java Virtual Machine (JVM) for a particular operating system must be installed to execute the Java Bytecode. The Java Virtual Machine (JVM) translates the Java Bytecode into machine code that the operating system may execute.
According to the TIOBE index, Java has grown to be the third most popular language because of its adaptability. Java is also easier to learn for novices than languages like C and C++ due to its simplicity. According to Glassdoor, the average yearly salary for a Java developer in the US is $110,713. Consequently, there is a high need for Java developers!
Top Java Courses for Beginners
The University of Helsinki’s Java Programming I takes the top rank for the finest free Java course. Before taking any other courses on this list, you should check out this MOOC.
Thanks to its thorough curriculum, many programming tasks with answers, and automated testing, this demanding course will take you from a total beginner to an intermediate Java programmer. Additionally, a volunteer-run active telegram group is also there! What more could a free course possibly offer? Oh, and it also gives out a voucher for free.
This MOOCs integration with the NetBeans coding editor is another unique feature that lets you start using professional tools right away. You’ll understand the fundamentals of computer programming, along with algorithms and object-oriented programming, after the course.
If you’ve never written a single line of code before, the course starts with a programming introduction. You’ll become familiar with the fundamentals of programming, such as variables, mathematical and logical operators, and loops, as well as the mindset and tools you should adopt as a programmer. For example, you’ll learn how to divide larger problems into smaller ones or how to use a debugger to find errors in your code when they inevitably occur.
Although they may be strong, computers are not intelligent. They are only able to carry out the instructions given to them; nothing else. As a result, you learn a few standard data structures and methods in this course. Data structures instruct the computer on how to store and display data, such as student grades in a class. Algorithms, on the other hand, instruct the computer on how to extract data from such data structures, such as identifying the pupil with the greatest class grade. The speed at which information is retrieved and stored depends on how well you implemented data structures and algorithms. And in a world that moves quickly, quickness is crucial.
Additionally, you’ll study many programming paradigms, which instruct us on how to organize our program. Because Java is an object-oriented programming language, it will be the course’s main topic of study. The goal of object-oriented programming is to create a bigger image out of a multitude of smaller ones. For illustration, consider a typical dwelling. A room may be 800 square feet or 1500 square feet, and a wall may be yellow or white. A ceiling may be slanted or flat. However, while having different qualities, they all have the similar feature of having walls, floors, and rooms. This top-down method of constructing code is used in object-oriented programming, particularly when implementing real-world objects.
The seven components of the course last between 10 and 20 hours apiece, depending on your existing programming experience. Each component includes a unique series of exercises that are scored automatically. Once you have finished at least 80% of the activities in each phase, you will get a certificate of completion.
Because it is one of Udemy’s most recent Java courses, it is also the most recent. You will learn how to write in Java using tools like JShell, which was added in Java 9. It’s a fantastic tool that makes testing things out in Java quite simple.
Additionally, the course format is excellent and employs a step-by-step teaching approach. Having taken some of the instructor’s Spring courses in the past, I like his approach and teaching manner.
The course is quite thorough and covers all key Java ideas, including the fundamentals of Java, Object-Oriented Programming, Java Collections, Generics, Multithreading and Concurrency, Functional Programming Networking, File Handling, and Exception Handling.
If you are studying Java to gain a job, you will be quite comfortable understanding and developing Java programs after you have completed a course. You should also feel confident to take any Java interview. The greatest part is that it is now free, making it the finest and most current Java training available.
All of the course’s chapters and related materials will be available to you for free as long as you are a registered student.
A very thorough introduction to Java programming is provided through Princeton University’s Computer Science: Programming with a Purpose on Coursera.
This free-to-audit course, which is also mostly based on coding, intends to educate programming in the context of computational science. After completing this course, you will not only be an expert in Java but also familiar with several basic ideas used in other programming languages. You don’t need to have any previous programming knowledge to take this course.
Before covering the structure of a basic Java program, including variables, conditional statements, loops, arrays, and more, the course starts with a short history of the Java programming language. Every program must be able to interact, which means that it must be able to take input from the user and produce a result. You’ll learn how to do this in Java.
The foundation of modular programming, Java’s methods, and libraries will be covered next. Modular programming favors nice and tidy chunks of code to a messy, large network of codes. Algorithms, which are instructions provided to a computer to produce the desired outcome, will be studied as a consequence of this. You’ll discover how to use scientific methods to evaluate the effectiveness of algorithms.
The next step is Java object-oriented programming. You’ll develop the data types that you’ll use in your applications as conceptual abstractions of real-world ideas. The result of this will be the writing of software that visualizes the well-known Mandelbrot set using complex integers.
The last section of the course provides a summary of significant programming language-related concerns. The course covers essential topics such as type checking, object-oriented programming, functional programming, garbage collection, and these languages’ core characteristics while providing a short historical background.
This course covers all crucial Java concepts, including variables, methods, control statements, loops, arrays, and Strings, as well as object-oriented programming, file handling, databases, multithreading, collections, etc., much like the previous two courses.
It also discusses Java 8’s new features and functional programming, as well as Java FX, which enables the development of Swing-like GUI-based Java applications. Even the whole construction of a Tic-Tac-Toe game will be covered in this course. In other words, a decent introduction to Java programming.
Getting Started with Java Programming You will learn how to create Java code, the fundamentals of OOP, and software engineering methodologies by beginning to program in Java.
The five-week, limited-access course is free to audit and explains programming using everyday examples like calculators and video games. As the course moves further, important ideas like functional abstraction, the object-oriented programming (OOP) paradigm, and application programming interfaces (APIs) will be taught.
Three five-week modules make up the course: 1. Gain a fundamental understanding of the Java programming language; 2. Learn how to create effective and proper applications; 3. take on data structure issues.
The course begins by introducing you to basic programming concepts like values and expressions, as well as how to include decision-making in your program and extend its usefulness through loops. The description of methods, which are reusable chunks of code that may be called from anywhere in the program, follows. You will then develop and use recursive algorithms as a result.
The object-oriented programming (OOP) paradigm will also be covered. You’ll learn about the fundamental principles of OOP, including inheritance and polymorphism, as well as why it’s best to have reusable code components.
Blockly, Codeboard, and Greenfoot are three visible and straightforward tools that are used throughout the course to facilitate the creation of short applications. Codeboard lets you understand more specifics about Java grammar, Greenfoot is an IDE (Integrated Developed Environment) that you install on your computer, and Blockly enables you to program using blocks and prevent syntax issues.
You will be tested on the material you learned in a lab each week. You will also be given examples and case studies so you may work with colleagues or create simple systems on your own.
Another outstanding, thorough, and current course to learn Java programming in 2022 is this one. This course, developed by Java specialist and IT professional Karthikeya T, will provide you with all the knowledge you need to master Java and become a prosperous Java Developer in 2022.
This course is ideal for those who are new to Java, but it’s also fantastic for those who have some expertise since Karthikeya thoroughly discusses ideas that will not only show you how to use a certain Java tool or class but also when and why you should use that class exclusively.
To help you remember what you’ve learned, the course is also incredibly interactive and packed with quizzes, activities, and assignments. This is the ideal way to learn since if you don’t utilize what you learn to construct something or solve an issue, you’ll quickly forget it. This training is specifically designed to prevent patterns of learning and forgetting.
This is a premium course that costs roughly $99, but I was able to find a pretty good deal for you guys, so you can get it for only $3 for a short period (only available with the link below).
You may be thinking that there is a lot to learn and a lot of courses to enroll in, but you shouldn’t worry. You probably already know most of the information, but there are also many helpful free sites you can use. I’ve linked to some of them here and there along with the greatest resources, which are undoubtedly not free but are worthwhile for your money.
Although you are free to select the course you want, I am a particular admirer of Udemy courses since they are extremely reasonable and provide a lot of value for a very little amount of money. I won’t be compensated if you purchase one of these courses, though.
In the end, you need to be sufficiently knowledgeable and experienced regarding the topics covered here. I wish you well as you learn Java! Even though it won’t be simple, by following this road map and manual, you’ll go one step closer to realizing your dream of becoming a Java developer.
