When the code runs, it creates an object array `o` with two elements, one of type `A` and one of type `B`. Then it prints out the first (`o[0]`) and second (`o[1]`) elements of the array using `System.out.print()`. 
The `toString()` method is called on each object when it is printed. `A` overrides `toString()` to return the `String` "A", and `B` overrides it to return the `String` "B". Therefore, the output will be "AB".
