Java IO streaming data streams datainputstream, DataOutputStream, Bytearrayinputstream, Bytearrayoutputstream

Example program:

 Packageio;ImportJava.io.ByteArrayInputStream;ImportJava.io.ByteArrayOutputStream;ImportJava.io.DataInputStream;ImportJava.io.DataOutputStream;Importjava.io.IOException; Public classTestdatastream { Public Static voidMain (string[] args) {/*** Create a byte array in memory, Bytearrayoutputstream this pipe is godless to the memory*/Bytearrayoutputstream BAOs=NewBytearrayoutputstream (); //writes the basic Java data type to the output streamDataOutputStream dos =NewDataOutputStream (BAOs); Try {            //writes a double type, 8 bytesdos.writedouble (Math.random ()); Dos.writeboolean (true);//Boolean type 1 bytes                        /*** Equivalent to this pipe godless to the top of Bytearrayoutputstream.
