Java input and output basic operations example

The inheritance of these classes is somewhat similar, take one as a sample, and understand the mechanism.

 PackageCc.openhome;ImportJava.io.*; Public classMember {PrivateString number; PrivateString name; Private intAge ;  PublicMember (string number, string name,intAge ) {         This. Number =Number ;  This. Name =name;  This. Age =Age ; } @Override PublicString toString () {returnString.Format ("(%s,%s,%d)", number, name, age); }         Public voidSave () {Try{dataoutputstream Output=NewDataOutputStream (NewFileOutputStream (number));            Output.writeutf (number);            OUTPUT.WRITEUTF (name);        Output.writeint (age); } Catch(IOException ex) {Throw NewRuntimeException (ex); }    }         Public StaticMember Load (String number) {Member Member=NULL; Try{DataInputStream input=NewDataInputStream (NewFileInputStream (number)); Member=NewMember (Input.readutf (), Input.readutf (), Input.readint ()); } Catch(IOException ex) {Throw NewRuntimeException (ex); }        returnmember; }}

 Package Cc.openhome; import java.io.*;  Public class Memberdemo {    publicstaticvoid  main (string[] args) {         New Member ("B1234", "justing", "a"),new Member ("B4532", "Monica", and All)};          for (Member member:members) {            member.save ();        }        System.out.println (Member.load ("B1234"));}    }
