datainputstream readfully

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 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

);//Writes a string to the basic output stream in a machine-independent way with the UTF-8 revision. The method first writes two bytes with Writeshort to indicate the number of bytes later. int size ();//Returns the current value of written DataInputStream allows applications to read basic Java data types from the underlying input stream in a machine-independent manner. Applications can use data output streams to write data that is read by th

Both datainputstream and dataoutputstream are decorative classes for input and output streams in Java, which are easy to use. Today we will discuss the encoding problems encountered when using this class.

Usage and precautions of datainputstream and dataoutputstream Import Java. io. *; If you directly use datainputstream to read the file content, an exception is thrown: At this time, even the manual income data cannot be read, and there is no content in the file. Solution: you must first use dataoutputstream to write data, and then use datainputstream to re

// Remember the data type that is used for output, // For example, DOS. writeint (100); write, read: DIS. readutf () sometimes has unexpected errors, so you must always remember what data type is used for data type output reading. // Datainputstream (binary input stream) Public class datainputstreamdemo { // Binary stream (read operation) Public static void main (string [] ARGs ){ Fileinputstream FCM = NULL; Data
