What you'll learn

Business needs are becoming increasingly complex, and software needs to keep up. In most cases, object-oriented programming (OOP) is the most pragmatic and elegant way of modeling software solutions. In this course, Java SE 21 Developer (Exam 1Z0-830): Object-oriented Programming, you’ll learn to model real business domains using OOP and prepare for the Java 1Z0-830 certification. First, you’ll explore some basic concepts of working with OOP, such as objects, classes, and constructors. Next, you’ll discover how to add state and behavior to your objects using fields and methods, both instance and static. Then, you’ll learn how to use encapsulation, inheritance, interfaces, and polymorphism to deliver more robust software applications. Finally, you'll understand when and how to use Java records, enums, and nested classes. When you’re finished with this course, you’ll have the skills and knowledge of using OOP effectively in Java which is needed to create complex software applications and to take the Java IZ0-830 exam.
