Hi, Can U help me How 2 solve "StreamCorruptedException" problem. This exception i'm getting when i'm trying 2 use readObject(). First time it is giving EOFException().from next time onwards it is giving StreamCorruptedException(). code is: ------------------------------------------ import java.io.*; public class FileTry1 { // instance variables - replace the example below with your own private UserRec currUser;
/** * Constructor for objects of class FileTry1 */ public FileTry1() { // initialise instance variables UserRec u1 = new UserRec(0, "John3", 1000); UserRec u2 = new UserRec(1, "joe3", 2000); UserRec u3 = new UserRec(100, "naren", 2000); try { FileOutputStream ostream = new FileOutputStream("t.tmp", true); ObjectOutputStream p = new ObjectOutputStream(ostream);
p.writeObject(u1); p.writeObject(u2); p.writeObject(u3); p.flush(); ostream.close(); p.close(); } catch (Exception e) { System.out.println(e); } // end catch ReadIt ri = new ReadIt(); }
public static void main(String args[] ) { new FileTry1(); System.exit(0); }
} // end class FileTry1 --------------------------------- import java.io.*; public class UserRec implements Serializable { // instance variables - replace the example below with your own public int userID; public String userName; public int salary;
/** * Constructor for objects of class UserRec */ public UserRec() { // initialise instance variables userID = 0; userName = ""; salary = 0; } public UserRec(int id, String name, int sal) { // overridden constructor w/ values userID = id; userName = name; salary = sal; } // end constructor...
} ----------------------------------------
import java.io.*; public class ReadIt { // instance variables - replace the example below with your own private UserRec urec;
/** * Constructor for objects of class ReadIt */ public ReadIt() { // initialise instance variables urec = new UserRec(); FileInputStream istream = null; ObjectInputStream p = null; // now try to read the file we just wrote try { istream = new FileInputStream("t.tmp"); p = new ObjectInputStream(istream); System.out.println("Now going to try to read the file back in"); boolean EOF = false; int count=0; while ( !EOF ) { try { UserRec t_urec = (UserRec) p.readObject(); System.out.println("rec No.: " + t_urec.userID + " Name: " + t_urec.userName); if(++count == 4) break; } // end try catch (Exception f) { EOF = true; System.out.println("in ReadIt at EOF catch: " + f); f.printStackTrace();
} // end catch EOF } // end while ( !EOF ) istream.close(); p.close(); } // end try catch (Exception ee) { System.out.println("Overall ReadIt catch: " +ee); }
} // end ReadIt() } // end class ReadIt ------------------------------------ Thanks in advance Naren.
