Java BufferedWriter flush() Example Below is a java code demonstrates the use of flush() method of BufferedWriter class. The example presented might be simple however it shows the behaviour of the flush() method. 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. BufferedWriter(Writer out, int size): Creates a new buffered character-output stream that uses an output buffer of the given size. Methods: write() : java.io.BufferedWriter.write(int arg) writes a single character that is specified by an integer argument. The java.io.BufferedWriter.close() method flushes the characters from the stream and then closes it. After closing, further write(), append() or flush() invocations will throw an IOException. Declaration. Following is the declaration for java.io.BufferedWriter.close() method. public Writer close() Parameters. NA. Return Value
If the requested length is at least as large as the buffer, however, then this method will flush the buffer and write the characters directly to the underlying stream. Thus redundant BufferedWriter s will not copy data unnecessarily.
The BufferedWriter will already flush when it fills its buffer. From the docs of BufferedWriter.write:. Ordinarily this method stores characters from the given array into this stream's buffer, flushing the buffer to the underlying stream as needed. If the requested length is at least as large as the buffer, however, then this method will flush the buffer and write the characters directly to the underlying stream. Thus redundant BufferedWriter s will not copy data unnecessarily. Java BufferedWriter flush() Example Below is a java code demonstrates the use of flush() method of BufferedWriter class.

Return Value Here, the internal buffer of the BufferedWriter has the default size of 8192 characters. However, we can specify the size of the internal buffer as well. // Creates a BufferedWriter with specified size internal buffer BufferedWriter buffer = new BufferedWriter(file, int size); The buffer will help to write characters to the files more efficiently.
