"Help" Java variable length parameter method call problem

Do not say nonsense, directly on the code:

1  Packagemytest;2 3 Importjava.util.List;4 5  Public classTestClass {6 7      Public voidMethod (list<object>list) {8System.out.println ("Method with param list<object> invoked!");9     }Ten      One      Public voidmethod (Object ... objects) { ASystem.out.println ("Method with param Object ... invoked!"); -     } -}

1  Packagemytest;2 3 Importjava.util.ArrayList;4 Importjava.util.List;5 6  Public classMain {7 8      Public Static voidMain (string[] args) {9list<string> list =NewArraylist<string>();TenList.add ("AA"); OneList.add ("BB"); AList.add ("CC"); -          -TestClass t =NewTestClass (); the          - T.method (list); -     } -  +}

The main method executes the result:

Method with param Object ... invoked!

Why an overloaded method is a parameter of LIST<OBJECT> A parameter is an object ..., the calling method has a parameter type of LIST<STRING>, and the actual execution of the argument is object ... Method?
