Free Java Courses

All course content is free to learn. A certificate can be obtained for a nominal fee after successfully completing the course

These modules are designed to be highly focused and efficient. Most courses take only 1 to 3 hours to complete. This allows you to master a specific concept, such as Lambda Expressions, Generics, or the Merge Sort algorithm, all in a single afternoon.

You gain knowledge of Java fundamentals, array, data types, functions, OOPs concepts in Java, and many other crucial concepts in Java programming through Great Learning Academy’s free Java courses.  

The Java Projects and Building Games using Java modules are entirely hands-on. You will build functional applications, including classic games like Tic Tac Toe and Snake. These projects give you practical experience in applying logic and structuring applications, helping you build a tangible portfolio for job interviews.

These Java courses are provided by Great Learning Academy for free, allowing any learner to learn Java and gain crucial skills.  

Learners, from freshers to working professionals who wish to learn Java and upskill, can enroll in these free Java courses and earn certificates of course completion.  

The Java Data Structures for Beginners course is the perfect starting point. It covers the implementation and traversal of linear structures, including Arrays, Stacks, Queues, and Linked Lists. Understanding these basics is essential before moving on to complex memory allocation.

The algorithm modules cover the exact problem-solving techniques tested by top tech companies. You will learn algorithmic time complexity and master Sorting algorithms (Bubble, Quick, Merge, Insertion) as well as searching methods (Linear, Binary). You will also develop advanced logic skills by studying Greedy Algorithms, Divide and Conquer, Backtracking, and Pattern Matching (KMP), enabling you to solve complex scenarios like the Rat in a Maze and the Fractional Knapsack problem.

Great Learning Academy is the visionary initiative by Great Learning, the leading e-Learning platform, to offer free industry-relevant courses. Free Java courses contain courses ranging from beginner-level to advanced-level to help learners choose the best fit for them.

Yes. The Java Virtual Machine (JVM) Introduction course explains the JVM's internal workings. You will learn about JVM architecture, automated memory management (Garbage Collection), and how to use the Eclipse Memory Analyzer Tool to optimize your software's performance.

We offer specialized modules that apply Java to complex mathematics. You will learn how to solve linear equations and find matrix ranks using Gauss-Elimination, Gauss-Jordan, and Gauss-Seidel methods, alongside calculating eigenvalues and eigenvectors for computational programming.

You will learn the most critical algorithms used in software engineering to optimize performance and time complexity. The curriculum covers Bubble Sort, Quick Sort, Merge Sort, Insertion Sort, and Linear and Binary Search methods.
