The earliest use of the queue to hold data, the time node for a one-time read and FTP transmission, but the queue data is too slow, so reuse the memory stream to solve the performance of the data, on the other hand, the data for seamless FTP upload. 1, first set up a memory stream MemoryStream, and build its StreamWriter MemoryStream data_stream = new MemoryStream (); StreamWriter data_writer = new Stream

Stream Data Stream in Java 8 and java8Stream data StreamFilter repeated Elements The Stream interface supports the distinct method, which returns a Stream of elements (implemented based on the hashCode and equals methods of the elements generated by the Stream. For example,

Stream ends with a byte stream, and reader and writer end up with a character streamThe difference between the two is read and write, one is read by Byte, and the other is by character. Operation ByteReading and writing a file requires that the content be processed in rows, such as comparing specific characters, and a character stream is typically selected when p

serializing and deserializing streamsThe flow of operations used to read an object from a stream ObjectInputStream called a deserialization streamThe flow of operations used to write objects to the stream ObjectOutputStream is called a serialized stream (the object is saved to a file)L Features: For manipulating objects . You can write an object to a file, or you

[JavaSE] I/O Stream (pipeline stream) and javaseio Stream pipeline Previously, I/O streams were used to require an intermediate array. Pipeline streams can be directly input to the output stream. They are generally used with multiple threads. When no data is read from the stream
