ObjectInputStream available() method doesn't work as expected (Java)

Question

I\'ve been trying to figure out why a method I\'ve written to read objects from a file didn\'t work and realized that the available() method of ObjectInputStream gave 0 even

Answer 1

I found some trick! If you still want to use .available() to read all objects to the end, you can add an integer (ex: out.writeInt(0)) before adding each Object (ex: out.writeObject(obj)) when you write to the file and also read integer before reading each Object. So .available() can read byte left on file and won't be crash! Hope it helps you!
