Hello Sachith,
This is Hariprasad Govardhanam, Regarding your problem about storing of data in a
file.
Sorry, I didn't see your mail, I know that you asked this for your assignment, and
the last day is over. But it is always better to remember what you have to. I don't
know why people think deep when the answer lies on the top.
The problem is very simple, just store all the data into a Vector then simply
store that vector into a file using a ObjectOutputStream. And this works, it is very
very simple, no problems at all. If there is a problem occuring, then that is because
of your code. I have written a program using this.
Code to write into file:
try {
FileOutputStream foutcd=new FileOutputStream("CD.jxt");
ObjectOutputStream objoutcd=new ObjectOutputStream(foutcd);
objoutcd.writeObject(Cds);
objoutcd.close();
}catch(FileNotFoundException e){
JOptionPane.showMessageDialog(null,"Unable to save");
}catch(IOException e){
JOptionPane.showMessageDialog(null,"IOException Caught");
e.printStackTrace();
};
And the code to read it is:
try {
FileInputStream fpcd=new FileInputStream("myfile");
ObjectInputStream objcd=new ObjectInputStream(fpcd);
Cds=(Vector)objcd.readObject();
objcd.close();
}catch(FileNotFoundException e) {
JOptionPane.showMessageDialog(null,"File Not Found");
}catch(IOException e){
JOptionPane.showMessageDialog(null,"IOException caught");
e.printStackTrace();
}catch(Exception e){ };
Hope this is useful for you
