Introduction to OO Programming with Java is course 2 of the Core Java Specialization. After completing this course, you'll be able to create simple Java classes that exhibit the principle of Encapsulation, to import other classes for use, to work with Strings, print output and use advanced math functions. We'll begin with a brief refresher on necessary concepts from Object-Oriented Programming. Next, we'll introduce basic Java concepts regarding classes, enabling you to start writing simple Java classes with attributes and methods. We'll introduce the idea of instances, or objects created from classes, so that you can start to build object-oriented solutions. Finally, we'll cover namespaces and Java Libraries to explain how Java packages classes, so that everyone can develop code without name collisions. You will be able to organize and access classes, as well as use selected standard classes from the Java runtime environment. To be successful in this course, you should have taken Course 1: Introduction to Java or have equivalent knowledge.
