Java Code Example for BufferedOutputStream to Write OutputStream

BufferedOutputStream can be setup to write the bytes to the underlying output stream without necessarily causing call to the underlying system for each byte written. BufferedOutputStream class has below two constructor : BufferedOutputStream(OutputStream out) – Creates a new buffered output stream to write data to the specified underlying output stream. BufferedOutputStream(OutputStream out, int size) – …

Java Code Example for BufferedInputStream : mark() method

BufferedInputStream mark() method marks the current position in this input stream. A subsequent call to the reset method repositions this stream at the last marked position so that subsequent reads re-read the same bytes. The readlimit argument tells this input stream to allow that many bytes to be read before the mark position gets invalidated. …

Java Code for BufferedInputStream : reset() Method Example

BufferedInputStream reset() method repositions the current stream to the position at the time the mark method was called last time on this input stream. If markpos is -1 (no mark has been set or the mark has been invalidated), an IOException is thrown. Otherwise, pos is set equal to markpos. Overrides: reset in class FilterInputStream …

Java Code Example for BufferedInputStream: skip() method

skip() method of BufferedInputStream class creates a byte array and then repeatedly reads into it until n bytes have been read or the end of the stream has been reached. Skips over and discards n bytes of data from this input stream. The skip method may, for a variety of reasons, end up skipping over …

Java Code Example for BufferedInputStream: close() method

close() method of BufferedInputStream closes the current input stream and releases any system resources associated with the stream. Once the stream has been closed, further read(), available(), reset(), or skip() invocations will throw an IOException. Closing a previously closed stream has no effect.

Java Code Example for BufferedInputStream: read(byte[] b,int off,int len) Method

Reads bytes from this byte-input stream into the specified byte array, starting at the given offset. It attempts to read as many bytes as possible by repeatedly invoking the read method of the underlying stream. This iterated read continues until one of the following conditions becomes true: The specified number of bytes have been read, …

Java Code Example for BufferedInputStream: read() Method

read() method of BufferedInputStream class reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the …

Java Code Example for BufferedInputStream to read file

BufferedInputStream adds an additionally capability to InputStream by buffering the input. When instance of BufferedInputStream is created, an internal array is created to buffer the input data. As bytes from stream are read or skipped, the internal buffer is refilled as necessary from the contained input stream, many bytes at a time. BufferedInputStream class has …

Code Example for BufferedInputStream: available() method

BufferedInputStream available() method returns the total count of bytes that can be read or skipped over from the input stream without blocking by next invocation of a method for the input stream. The next invocation might be the same thread or another thread. A single read or skip of this many bytes will not block, …
