Lesson 6: More Methods and Classes (2.0) hours

More Methods and Classes teaches you how to explain how objects can be passed to and returned from methods, describe how and why you can overload methods and constructors, explain the purpose and use of recursion, use the static keyword, employ nested and inner classes, and use variable-length arguments. This course provides detail about Java methods and classes, including controlling access to the members of a class, passing and returning objects, overloading methods, and other features. Topics include Access to class members, Passing objects to methods, Overloading methods and constructors, Recursion, Understanding static, The Quicksort, Nested and inner classes, and Variable length arguments.

Lesson 7: Inheritance (2.0) hours

Inheritance teaches you how to call superclass constructors, use super, create multilevel class hierarchy, override methods, achieve dynamic method dispatch, and use final. This course provides a detailed examination of inheritance, one of the three foundation principles of object-oriented programming. After taking this course the learner will know the meaning of inheritance and how it allows the creation of hierarchical classifications. Topics include Inheritance basics, Constructors and inheritance, Accessing superclass members, Multilevel hierarchies, Superclass references, Method overriding, Abstract classes, Using final, and The Object class.

Lesson 8: Packages and Interfaces (2.0) hours

Packages and Interfaces teaches you how to use packages, apply access specifiers, import packages, explain interface fundamentals, implement an interface, and extend interfaces. This course examines two of Java's most innovative features: packages and interfaces. You'll also learn how packages affect access, and how to apply interface references. Topics include Packages, Member access, Protected members, Importing packages, Interfaces, Interface references, and Variables in interfaces.

Lesson 9: Exception Handling (2.0) hours

Exception Handling teaches you how to describe how exceptions are handled in the Java runtime environment, write try/catch/finally blocks to monitor for exceptions and handle them, manually throw an exception, use Java's built-in exceptions, and create your own exceptions. After taking this course, you will know how to handle runtime errors in Java programs. The course shows how to use a try/catch/finally block to add an exception handling routine that will monitor for program errors and respond to them. Topics include The exception hierarchy, Uncaught exceptions, Multiple catch statements, Nesting try blocks, Throwing an exception, Using finally, The throws clause, Built-in exceptions, and Exception subclasses.

Lesson 10: Using I/O (2.0) hours

Using I/O teaches you how to use byte streams, use character streams, use predefined streams, read and write binary data, read and write random access files, and apply Java's type wrappers to convert numeric strings. After taking this course, you will know how to handle both console I/O and file I/O for Java. This course will introduce you to the most important and commonly used features of Java I/O.

Lesson 13: Generics (3.0) hours

Generics teaches you how to describe the role of generics in Java programming, create generic classes, interfaces, and methods, use the generic wildcard argument to represent unknown types, use raw types to make legacy code compatible with generic code, explain how the Java compiler uses erasure to implement generics, and list the restrictions to using generics in Java. This course introduces you to the generics feature that was added to Java with the Java 2 5.0 release. It demonstrates how to create generic classes, interfaces, and methods in which the type of data on which they operate is specified as a parameter.
