Feb 12, 2020 · The optimal buffer size depends on factors like the type of the input stream and the hardware on which the code is running. For this reason, to achieve the ideal buffer size, we have to find it ourselves by experimenting. It's best to use powers of 2 as buffer size since most hardware devices have a power of 2 as the block size.
Apr 08, 2019 · Hi guys, can anyone please help me with this? I’m trying to write 10 lines in a .doc file with a buffered writer. Each line contains a string and a number, as below: BufferedWriter(Writer wrt) It is used to create a buffered character output stream that uses the default size for an output buffer. BufferedWriter(Writer wrt, int size) It is used to create a buffered character output stream that uses the specified size for an output buffer. We will be using write() method of BufferedWriter to write the text into a file. The advantage of using BufferedWriter is that it writes text to a character-output stream, buffering characters so as to provide for the efficient writing (better performance) of single characters, arrays, and strings. Complete example: Write to file using Opens or creates a file for writing, returning a BufferedWriter to write text to the file in an efficient manner. Parameters: path - the path to the file options - options specifying how the file is opened Returns: a new buffered writer, with default buffer size, to write text to the file Examples
BufferedWriter public BufferedWriter(Writer out, int sz) Suppressed. default deny Creates a new buffered character-output stream that uses an output buffer of the given size. Parameters: out - A Writer sz - Output-buffer size, a positive integer Throws: IllegalArgumentException - If sz is = 0
BufferedWriter is a sub class of java.io.Writer class. BufferedWriter writes text to character output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings. The buffer size may be specified, or the default size may be used. The default is large enough for most purposes. The BufferedWriter on the other hand, show that it uses and 8192 byte buffer size (default), which can be configured by the user to any other desired size. And to further muddy the waters, the Java 6 implementation of OutputStreamWriter actually delegates to a StreamEncoder , which uses its own buffer with a default size of 8192 bytes.

public class BufferedWriter extends Writer. Write text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings. The buffer size may be specified, or the default size may be accepted. The default is large enough for most purposes. Dec 16, 2017 · Without a BufferedWriter this could make 200 (2 * 100) system calls and writes to disk which is inefficient. With a BufferedWriter, these can all be buffered together and as the default buffer size is 8192 characters this become just 1 system call to write. BufferedWriter provides efficient method of writing single characters, arrays, and strings. You can specify a buffer size but the default is large enough for most purposes. A newLine() method is provided, which uses the platform's own notion of line separator as defined by the system property line.separator.
