Java InputStream Handling In Java, InputStream handling is essential for reading data from files, network connections, or other input sources. Classes like BufferedReader and InputStreamReader are commonly used to wrap an InputStream for efficient reading. Methods such as read(), readLine(), or readAllBytes() allow data processing in various formats. Proper resource management with try-with-resources ensures that streams are closed after use. This functionality is fundamental for Java's robust input handling capabilities in diverse applications.
