IO error
I'm trying to write an object to a binary file. I'm reusing code that I used before and it worked, but this time its trowing a IOException. The error is thrown when it tries to write the board to the file.
publicclass IOUtilities{
public IOUtilities(){}
publicvoid saveGame(String filename, MancalaBoard board){
if((filename!=null)&&(!filename.equals(""))){
ObjectOutputStream outStream=null;
try{
outStream =new ObjectOutputStream(new FileOutputStream(new File(filename)));
outStream.writeObject(board);
outStream.close();
System.out.println("Game saved Successfully");
}
catch(FileNotFoundException e){
System.out.println("ERROR: File not found => "+e.getMessage());
}
catch(IOException e){
System.out.println("ERROR: IO ERROR => "+e.getMessage());
}
}
}
public MancalaBoard loadGame(String filename){
if((filename!=null)&&(!filename.equals(""))){
ObjectInputStream inStream=null;
try{
inStream =new ObjectInputStream(new FileInputStream(filename));
MancalaBoard board = (MancalaBoard)inStream.readObject();
inStream.close();
return board;
}
catch(ClassNotFoundException e){
System.out.println("ERROR: Class not found => "+e.getMessage());
}
catch(FileNotFoundException e){
System.out.println("ERROR: File not found => "+e.getMessage());
}
catch(IOException e){
System.out.println("ERROR: IO ERROR => "+e.getMessage());
}
}
returnnull;
}
}
Any ideas? Thanks for any help/suggestions.
