java可变参数列表如何填充数组？

public class MyVarArgs {

    public static void main(String[] args) {

        printArray(1, 1.1F, 12.11);

        printArray("one", "two", "three", "four");

        printArray(new MyVarArgs(), new MyVarArgs());

        //数组作为参数

        Integer[] arr = new Integer[]{1,2,3,4};

        printArray((Object[]) arr);

        //参数为空

        printArray();

    }

    public static  void printArray(Object... args){

        for (Object obj : args){

            System.out.print(obj + " ");

        }

        System.out.println();

    }

}

/* 输出

1 1.1 12.11

one two three four

MyVarArgs@1b6d3586 MyVarArgs@4554617c

1 2 3 4
