In this section, we explore essential classes in Java that facilitate file handling. Java’s file handling capabilities are primarily embodied in the classes:
-
FileReader: This class is used for reading characters from a file. It is important for input operations where characters need to be processed.
-
BufferedReader: This complements FileReader by allowing efficient reading of text data, enabling the reading of lines one at a time instead of character by character. This enhances performance when managing large files.
-
FileWriter: This class is instrumental for writing character data to files, allowing programs to store processed data persistently.
-
PrintWriter: An extension of the functionality provided by FileWriter, this class enables writing formatted text output, making it easier to print user-friendly content.
Understanding these classes is crucial for effective file management in Java applications, as they form the backbone of data manipulation and persistence.
