Java processing files in the class, stream at the end of the use of byte stream, reader and writer End is a character stream. The difference between the two is read and write, one is read by Byte, and the other is by character. The bottom of the character stream is the byte

Java (4) -- IO stream, java -- io stream(1) Java Stream Input/Output Principle: In a Java program, input/output operations on data are performed in the

Java IO producer stream and byte streamI. Basic Concepts Stream: flows from one end to the other, from the source to the destination.Always centered on the program, it is a program and a file | array | Network Connection | database operations. Ii. IO stream classification 1. Flow Direction: Input

the byte stream processing classes are extended to the class, such as the above-mentioned Bytearrayinputstream class . Since the Inputstream.read () method is read only one byte at a time from the stream, the efficiency is very low. The Inputstream.read (byte[] b) or Inputstream.read (byte[] b,int off,int len) method, which can read multiple bytes at a time, is more efficient, so a byte byte array is creat

Alternat

Java IO stream, java IO stream character Refer stream: it also reads binary files, which will be decoded into characters that we can understand.Bytes stream = byte stream + Decoding(1)

Java The buffer stream itself has no IO function, but adds buffering to the other streams to improve efficiency, such as loading a wrapper over another stream . When the file or other target frequently read or write or operate inefficient, poor performance. This allows for more efficient reading and writing of information using buffered streams. Because the buffe

Java processing files in the class, stream at the end of the use of byte stream, reader and writer End is a character stream. The difference between the two is read and write, one is read by Byte, and the other is by character.The bottom of the character stream is the byte

followed by a stream of bytes, the following main introduction character stream, character stream and byte stream difference and file copy copy. In the program, a character equals two bytes, and a Chinese character occupies two bytes (General Limited interview will ask: A char can save a Chinese character, the answer i

The byte array input stream creates a byte array buffer in memory, and the data read from the input stream is saved in the byte array buffer. There are several ways to create a byte array input stream Object.The receive byte array is created as a parameter:New Bytearrayinputstream (byte [] a);Another way to create this is to receive a byte array, and two shaping
