There should be one way to construct an object. If we allow to use it as you gave, how many ways are there to construct an object? Won't there be a ambiguity in those two ways as you gave?

A super() call, as well as a this() call, calls a constructor and thus has to be the first statement in a constructor. If you put the super call first, the this call is not the first statement, and if you put the this call first, the super call is not the first statement, which will cause the compiler to complain.
