As you know, ourĀ free code lessons are not just video tutorials. They combine videos with many live examples andĀ practical hands-on exercises, whereĀ you write codeĀ after each lesson. So, youĀ learn Java coding through practice: by writing Java code. And you send your code to our online judge system, and you get an instant automated grading.

Remember thatĀ coding is a skill, which should be practiced. To learn to code, you should write code, every day, for a long time. Watching tutorials is not enough.Ā You should code! Now it’s your turn. Do your exercises!

Practical Exercises

Watch the videoĀ andĀ solve the problems.Ā To better understand the material, do the coding exercises and implement the knowledge you acquired. Writing code is the only way to master the skill of code.
