Overview/Description To enable the learner to implement inheritance and polymorphism in Java and to work with Java's static and final modifiers Target Audience Programmers with an understanding of procedural programming concepts who want to learn Java and object-oriented programming; programmers proficient in another object-oriented programming language who want to move to Java; programmers experienced in the Java language who want to make the upgrade to Java SE 6. Prerequisites Knowledge of programming principles and experience in procedural programming or scripting languages, such as Visual...

Overview/Description During normal program execution in Java, the caller method calls the worker method, the worker method performs an action and the execution returns to the caller method. When an exception occurs, an exception is thrown and either a special Exception object is passed to a special method-like catch block in the current method or execution returns to the caller method. Classes are grouped into packages to ease the management of the system. To deploy a Java application, you put the necessary files into a JAR file. A major performance penalty is paid in two-tier client/server....

Overview/Description In Java programming, methods have several uses. They make programs more readable and easier to maintain and development and maintenance is quicker. Methods are central to reusable software, they allow separate objects to communicate, and they distribute the work performed by the program. Method overloading allows several methods in a class to have the same name but different arguments, so the method signature is different. In Java, you encapsulate by hiding object fields to make all fields private. Constructors are method-like structures in a class that have the same name...

Overview/Description Understanding File I/O, concurrency, how to work with data via JDBC, and localization, are crucial to getting the most out of your Java applications. This course covers using the Path class to operate on file and directory paths, using the Files class to check, delete, copy or move a file or directory, reading and changing file and directory attributes, recursively accessing a directory tree, finding a file by using the PathMatcher class, and watching a directory for changes by using WatchService. In addition, it examines operating system task scheduling, defining,...
