10 Free Java Courses to learn Java Programming
Here are some free java courses to help you get started in your journey of becoming a Java developer.
The fact that you are reading this suggests you have already decided to learn Java. But first, let’s talk about Java before diving into the free java courses. In 1995, Sun Microsystems released Java, an object-oriented and concurrency-oriented programming language and platform similar to C++ with streamlined and enhanced features. Today, scientific applications, including natural language processing, are often written in Java. Since it is safe, portable, maintainable, and possesses better high-level concurrency tools than C++, it has become the language of choice. In comparison to C++, Java is easier to use and enforces the object-oriented programming model, which is close to the look & feel of C++. Moreover, in contrast to C++, which combines structure, generics, and object-oriented programming, Java focuses almost exclusively on object-oriented programming.
With Java, developers do not have to worry about the underlying computing architecture while writing and executing code. Unlike other programming languages, Java runs inside of its virtual machine sandbox, so you do not have to concern yourself with the platform and computing architecture of the platform. The virtual machine sandbox allows applications to run regardless of the platform, but it also means Java runtime environments are required, which is more resource-intensive.
Numerous devices use Java, including laptop computers, mobile devices, games consoles, health devices, notebook computers, data centers, gaming consoles, scientific supercomputers, cell phones, and more for developing Java applications. As well as being one of the most preferred languages for developing edge devices and Internet of Things apps, it is also the most popular programming language for android apps. Now let’s get back to our main topic and start learning Java.

2. Introduction to Java and Object-Oriented Programming [Coursera]
This course introduces Java syntax and how it differs from other languages such as Python. It also provides an overview of object-oriented programming and the Java language. During this course, students will learn how to write Java classes and methods and test their code using test-driven development and unit testing. Arrays, ArrayLists, and overloading methods are topics covered in this course.
In this Java course, you will:
- Understand the core concepts of object-oriented programming and Java’s features.
- Use Eclipse for writing and running Java code.
- Develop programs with Java collections, polymorphism, and overload methods to implement core object-oriented programming concepts.
- Test code by applying principles of test-driven development using Java’s unit testing framework.
In the first module, we will cover Java and object-oriented programming in this module. Specifically, it discusses how Java syntax differs from a language like Python. Furthermore, this module teaches you how to define your custom classes and methods and structure and inner workings of a Java class.
The second module will teach you how to test your code. The best practice is to write a set of unit tests and run them at any time against your program. This module covers how to do unit testing in Java and why we should do it. In addition, we’ll explore Java Arrays, which are collections of items, and ArrayLists, which are much more flexible than arrays. In Python, these work just like lists. In this course, we will continue referencing Java’s larger Collections Framework, which includes array lists.
The third module will cover static variables in Java classes. In addition, we’ll discuss static methods. It will also cover polymorphism in this module, which means overloading and overriding. Here we’ll discuss overloading, which is having more than one method with the same name within the same class.
