Java I/O Links

I/O Streams

• Byte Streams handle I/O of raw binary data.
• Character Streams handle I/O of character data, automatically handling translation to and from the local character set.
• Buffered Streams optimize input and output by reducing the number of calls to the native API.
• Scanning and Formatting allows a program to read and write formatted text.
• I/O from the Command Line describes the Standard Streams and the Console object.
• Data Streams handle binary I/O of primitive data type and String values.
• Object Streams handle binary I/O of objects.

File I/O (Featuring NIO.2)

• What is a Path? examines the concept of a path on a file system.
• The Path Class introduces the cornerstone class of the java.nio.file package.
• Path Operations looks at methods in the Path class that deal with syntactic operations.
• File Operations introduces concepts common to many of the file I/O methods.
• Checking a File or Directory shows how to check a file’s existence and its level of accessibility.
• Deleting a File or Directory.
• Copying a File or Directory.
• Moving a File or Directory.
• Managing Metadata explains how to read and set file attributes.
• Reading, Writing and Creating Files shows the stream and channel methods for reading and writing files.
• Random Access Files shows how to read or write files in a non-sequentially manner.
• Creating and Reading Directories covers API specific to directories, such as how to list a directory’s contents.
• Links, Symbolic or Otherwise covers issues specific to symbolic and hard links.
• Walking the File Tree demonstrates how to recursively visit each file and directory in a file tree.
• Finding Files shows how to search for files using pattern matching.
• Watching a Directory for Changes shows how to use the watch service to detect files that are added, removed or updated in one or more directories.
• Other Useful Methods covers important API that didn’t fit elsewhere in the lesson.
• Legacy File I/O Code shows how to leverage Path functionality if you have older code using the java.io.File class. A table mapping java.io.File API tojava.nio.file API is provided.
