Study Notes
Design Patterns
- Design patterns are not a type of stream class. Design patterns are reusable solutions to common software design problems, while stream classes are used for data input and output.
Character Stream Classes
- Character stream classes work with data as characters rather than bytes. They are essentially a layer above byte streams, transforming byte data into characters. This simplifies working with textual data.
File Class
-
The primary use of the
Fileclass is to manipulate files and directories. It provides methods for operations such as creating, deleting, renaming, and getting information about files and directories.
Random Access
- Random access refers to reading or writing data at any position within a file without having to read through preceding data. This allows for direct access to specific parts of the file, which can be beneficial for large files or applications requiring fast data access.
Stream Class Types
-
FileInputStreamandFileOutputStreamare byte stream classes. They work directly with bytes and are suitable for handling binary data. -
FileReaderandFileWriterare character stream classes. They work with character data and are designed for text-based files. -
ObjectInputStreamandObjectOutputStreamare used for serialization and deserialization of objects. They allow you to save and load object data to and from files.
