Explore the essential elements of Java objects, classes, references and methods. During this course, you will discover the characteristics of a Java object. Define Java object components and properties. Use object references. Work with two References for one object. Study how an array of objects is stored in memory. Describe the basic forms of a constructor and a method. Other topics include how to create a class that implements a constructor, how to define method parameters, employ method overloading, and implement methods that return values of a specified type. Finally, you will study how to distinguish between local and instance variables.
