Document directory Main methods and constants in the file class Procedure Byte output stream: outputstream Byte input stream: inputstream Character output stream: writer Character input stream: Reader File class In the entire Io package, the only class that indicates the file itself is the file class. You can

Java IO stream byte stream, java IO stream byteI. Common file Operations File file = new File ("E: \ test \ javaIo"); System. out. println (file. isDirectory (); // determines whether the file is a directory (if the file does not exist, false is returned) System. out. println (file. isFile (); // determines whether the file is a specific file System. out. printl

The Java stream is processed into a character stream and a byte stream. A character stream processes a cell that is 2-byte Unicode characters, manipulating characters, character arrays, or strings, and a byte-stream processing unit of 1 bytes, manipulating bytes and byte arr

The operation of the byte stream and the character stream is basically the same, the difference is only the data unit of the operation is different: the data unit of the byte stream operation is the data unit character of bytes, character stream manipulation.InputStream and reader are the base classes for all input str

Difference between Java byte stream and hidden stream, java byte hidden stream The use of byte streams is very similar to that of byte streams. Are there other differences between the two in addition to the differences in the operation code?In fact, the byte stream itself does not use a buffer (memory) during operation

The operation of the byte stream and the character stream is basically the same, the difference is only the data unit of the operation is different: the data unit of the byte stream operation is the data unit character of bytes, character stream manipulation. InputStream and reader are the base classes for all input st

One, file streamThe FileStream class is primarily used to read and write disk files . Often used to store data or read configuration files to disk.Read file://File stream: Read FileStream FileStream = File.Open (@ "D:\test.txt", FileMode.Open); Initialize file stream byte[] array = new byte[filestream.length]; Initializes a byte array that is used to stage the read to byte filestream.read (array, 0, array

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 stream
