object array can't return 'null'?

Why is it that an array of ints, floats or Strings returns 'null' for an empty index and an array of Objects returns an error...:
Code:void setup() {
String[] lAsd = new String[10];
lAsd[0] = new String("j");
println(lAsd[0]);
println(lAsd[1]);
println();
Test[] lTst = new Test[10];
lTst[0] = new Test();
println(lTst[0]);
//println(lTst[1]);
}
class Test {
Test() {
}
}

(uncomment commented line)
Is there a way to test if a spot in an array of objects is null or not?
...or do I have to use Vectors for this?

an array of objects does give "null" for empty slots:
Object[] foo = new Object[10];
if (foo[0] == null)...
it's just that you're going through println(), which does something like:
objectInQuestion.toString()
that is the cause of the error.
