readfully readfully (byte[] b) Throws IOExceptionReads some bytes from a input stream and stores them into the buffer array B. The number of bytes read is equal to the length of B. This method blocks until one of the following conditions occurs: B.length bytes of input data is available, with which case a normal return is made. End of file is detected, in which case an eofexception is thrown. An I/O error occurs, in which case a ioexce

In the I/O class library, Java.io.InputStream and java.io.OutputStream represent byte input streams and byte output streams, which are abstract classes that cannot be instantiated, and the smallest unit in the data flow is bytes, so it is called a byte stream.The method of reading data in InputStream is as follows:1, int read ()Function: Reads a byte of data, and returns the read data, and if 1 is returned, it reads to the end of the input stream.2, i
