Error in read object from txt and show it

Question

The netbeans show this eroor

Error with I/O processes java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: katanemimena1.Account at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1351) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:369) at katanemimena1.ATM.actionPerformed(ATM.java:208)

ObjectInputStream in =null;
Account acc =null;
try{
in =new ObjectInputStream(new FileInputStream( "Accounts.txt"));
while
( (acc = (Account) in.readObject()) !=null){
System.out.println(acc);
}
}
catch(EOFException ex) {
System.out.println("End of file reached.");
}
catch(ClassNotFoundException ex) {
System.out.println("Error casting") ;
ex.printStackTrace();
}
catch(FileNotFoundException ex) {
System.out.println("Error specified file does not exist") ;
ex.printStackTrace();
}
catch(IOException ex) {
System.out.println("Error with I/O processes") ;
ex.printStackTrace();
}finally{
try{
in.close();
}
catch(IOException ex){
System.out.println("Another IOException during the closing");

a lot of thanks , but know is show me this katanemimena1.Account@1568654 but i want to show me 321 account with 1066E for example – Βίκτορας ανδρεάδης Feb 21 '13 at 17:55
Because You are printing your object. System.out.println(acc); By default it calls object's toString() method. You can also override this functionality by implementing also toString() method and print in any format You want – Arsen Alexanyan Feb 21 '13 at 17:58
