CodingBat is a free online platform that offers coding practice to help students build programming skills in Java and Python. Created by Nick Parlante, a computer science lecturer at Stanford, the site provides a wide range of coding challenges that gradually increase in difficulty, allowing learners to practice and improve their coding abilities at their own pace.
This tutorial focuses on Java, one of the most popular and versatile programming languages in the world. Java is known for its 'write once, run anywhere' capability, making it ideal for developing cross-platform applications. The exercises cover various aspects of Java programming, including basic syntax, control structures, arrays, strings, and object-oriented programming concepts.
