Thread: Serialization of lists

I have a list which I save by the following:

	public void saveList(ArrayUnsortedList<Wrestler> listOfWrestlersToSave) {
		System.out.println(listOfWrestlersToSave);
    	try{
		ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(FILENAME));
		out.close();
    	}
    	catch(Exception e){
    		System.out.println("Couldnt save");
    	}
 
	}

But I want to load this saved list on start of the program so I tried this:

	public SList loadList(String fileName){
		  SList loadedListOfWrestlers = new SArrayIndexedList();
 
		try{
			ObjectInputStream in = new ObjectInputStream(new FileInputStream(fileName));	
			loadedListOfWrestlers = (SList)in.readObject();
			System.out.println(loadedListOfWrestlers);
		}
		catch(Exception e){
			System.out.println(e);
		}
		return loadedListOfWrestlers;
 
	}

Additional details:
SList is a list (an abstract data type) which is an unsorted array that implements Serializable.
fileName is a string containing the name of the .dat file in which my saveList() method saved the list to.

But when I run loadlist() I get java.io.EOFException. I know few details are provided here, but I feel like if I provide all the details it'd be too much. So, in general, what could potentially be wrong in my load function that causes me to get java.io.EOFException?
