java--reads the contents of the file to the basic data type and string

writes the basic type data to the file, then reads it

 Packagecom.machuang.io.others;ImportJava.io.BufferedInputStream;ImportJava.io.BufferedOutputStream;ImportJava.io.DataInputStream;ImportJava.io.DataOutputStream;ImportJava.io.FileInputStream;ImportJava.io.FileOutputStream;Importjava.io.IOException; Public classDataStream { Public Static voidMain (string[] args)throwsIOException {String path= "F:/win10/test/data.txt";                Writebasictypes (path); //Connect to the file you want to readDataInputStream dis =NewDataInputStream (NewBufferedinputstream (NewFileInputStream (path)); //Read Operations        DoubleRecdou =dis.readdouble (); LongRECL =Dis.readlong (); String RecS=Dis.readutf (); System.out.println ("Recdou:\t" + Recdou + "\ n" + "recl:\t" + recl + "\ n" + "recs:\t" +RecS);            Dis.close (); }     Public Static voidWritebasictypes (String Despath)throwsIOException {//the data to be written        DoubleDatadou = 3.6; LongNUML = 100L; String Datastr= "Architecture"; //Associate a file written outDataOutputStream dos =NewDataOutputStream (NewBufferedoutputstream (NewFileOutputStream (Despath))        );        Dos.writedouble (Datadou);        Dos.writelong (NUML);                Dos.writeutf (DATASTR);        Dos.flush ();                    Dos.close (); }        }

The operation results are as follows
