Why is my array not being read in correctly from my file?

[gabie1121]

In one file, I save a TreeNode object, then an int, and then a byte array to a file named `huffmanTrial.huff`.
In another file I want to read in all three of those things and do work on them. I can read in the TreeNode just fine and the int, but when I get to reading in the byte array I get that it is of size zero. Is that saying that it doesn't exist? I am using `in.available()` after I read in the TreeNode and int so I can see how big I need to make my new byte array and I always get 0. Am I somehow saving the array wrongly or am I reading it in wrongly?

Here is where I save the objects:

     FileOutputStream fos = new FileOutputStream(savedFileName);
            ObjectOutputStream out = new ObjectOutputStream(fos);
 
            out.writeObject(root);
            out.writeInt(numberOfZeroesAdded);
            out.writeObject(encodedByteArray);
 
             out.close();

And here is where I am trying to read all three things in

  FileInputStream fis = new FileInputStream("huffmanTrial.huff");
            ObjectInputStream in = new ObjectInputStream(fis);
            root = (HuffmanNode) in.readObject();
            System.out.println("root "+ root.getCount());
            numberOfZeroesAdded = in.readInt();
            System.out.println("zeroes: "+numberOfZeroesAdded);
            sizeOfArray = in.available();
            System.out.println("Size of array: "+sizeOfArray);
            encodedByteArray = new byte[sizeOfArray];
            in.readFully(encodedByteArray);

I get `Size of array: 0`
I know for sure that the array that I am saving is not empty because just two lines before I save it, I print its contents. What am I doing wrong?

The code writes the array with writeObject() instead of write(). Did you try using write()?

Can you make a small simple program that compiles, executes and shows the problem.

Wow, yeah that totally did it. Thanks! I'm glad it was that simple. I guess I was thinking of my array, like an arrayList, as being an object.
