If you have a basic understanding of Java but feel ready to start digging deeper, this is the course for you. It's the perfect followup to our Java 8 beginners tutorial, but also suitable for those who've worked through other introductions, as well.You will start with a quick review of Java, then jump into learning about object inheritance, interfaces, abstract classes, and polymorphism. From there, Brian will teach you about exceptions and string manipulation, including custom exceptions, checked and unchecked exceptions, and the string tokenizer.
