Introduction Java Readers and Writers


	Lesson 1 Introduction Java Readers and Writers
		Welcome to Java Readers and Writers, the second course in the Networking with Java series. This course teaches you how to manipulate files and how to use the Reader and Writer classes to read and write text files. In addition, you'll learn about characters sets and encodings that allow Java to deal with those character sets. After completing this course, you'll be able to Manipulate files separately from their contents Determine information about a file Use the `FileDialog` class to choose files Connect readers and writers to input and output streams Use readers and writers to read and write strings and character arrays Use `BufferedReaders` to read text files one line at a time and use `BufferedWriters` to efficiently output them Write filter readers and writers that manipulate text before passing it on While Java Readers and Writers does not deal directly with network programming, it covers skills that are prerequisite for anyone interested in writing programs that communicate over networks. The Networking with Java series progresses from courses teaching these prerequisite skills to courses dealing specifically with writing Java programs that communicate over networks. Course length This course should take you approximately 15 hours to complete. You can expect to spend 15 to 30 minutes on each lesson. Some lessons will take you longer, especially if there is an exercise to submit, and others may take 10 minutes. These numbers are only estimates. Remember that your pace through the course is entirely up to you.
