PHPsocket implementation and Java readFully connection

: This article mainly introduces the connection between PHPsocket implementation and Java readFully. if you are interested in PHP tutorials, please refer to it. Java: DataInputStream stream = new DataInputStream (new BufferedInputStream (socket. getInputStream (); int I = stream. readInt (); byte [] B = newbyte [I]; stream.

Java datainputstream and DataOutputStream data input and output streams _java

DataInputStreamDataInputStream is the data input stream. It inherits from FilterInputStream.DataInputStream is used to decorate other input streams, which "allows applications to read basic Java data types from the underlying input stream in a machine-independent manner." Applications can use DataOutputStream (data output streams) to write data that is read by the DataInputStream (data input stream).DataInputStrea

Data input and output streams in Java-DataInputStream and DataOutputStream

1. Basic Concepts DataOutputStream data output stream allows applications to write Basic Java data types to the output stream in an appropriate way. Then the application can use the data input stream to read data. The DataOutputStream data input stream allows applications to read Basic Java data types from the underlying input stream in a machine-independent manner. Applications can use the data output stream to write data that is later read by the data input stream. Multi-threaded access is not

Readfully (byte[] b) is an adaptive solution to read the number of bytes in the stream problem (of course, determined by the number of arguments byte), there is read full, the end of the stream will automatically exit the block, see the JDK Help

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
