Io Stream and Propertiesio streamAn IO stream is an interface between a computer and the outside world or between a program and the rest of the computer. It is critical for any computer system,Thus the body of all I/O is actually built into the operating system. Separate programs generally allow the system to do most of the work for them.In Java programming, I/O

The input and output of Java is based on 4 abstract classes: InputStream, OutputStream, Reader, Writer. Inputsream and OutputStream are designed as byte-stream classes, while reader and writer are designed as character stream classes. In general, you should use a character stream class when working with characters or s

) {bao.write (i); } System.out.println (Bao.tostring ()); }}Data flowDataInputStream: The data input stream allows the application to read basic Java data types from the underlying input stream in a machine-independent manner. The application can use the data output stream to write data that is later read by the dat
