Overview/Description
Explore object-oriented programming concepts and techniques, in Java. During this course, you will discover various static methods and variables and explore a number of topics. These include the following: how to create and access static members, how to employ constants to represent unchangeable values, how to change numeric variable types through promotion and casting, and convert data values. Other topics include how to convert strings to their primitive numeric types, ciscover access control, and how to distinguish between the public interface and the internal workings of a class. Next, you will learn how to use public and private access modifiers, study encapsulation with object-oriented design, and create class setter methods with value checking. As you progress, other key areas include how to add method parameters to overload a constructor, how to pass an Object Reference, and pass a value. Finally, you will learn how to reassign a reference value in a method.
