Creating empty array

At 8;29 in the video, Craig created an empty array Treet[] treets = new Treet[0]. After that, he extracted the two Treet objects from the file treets.ser and put them in the array. How come we can add stuff to an array when we declare it to be of size 0? Please explain. Thanks!

That must be a typo or something, because like you are saying it can't be done:

        Object[] t = new Object[0];

        t[0] = new Object();

Gives an java.lang.ArrayIndexOutOfBoundsException
