How to pass object array as parameter in Java
提问by derrdji
The method is public static void method(Object[] params), how should I call it in the following scenarios?
方法是public static void method(Object[] params)，在以下场景中应该如何调用？
- with one object as parameter
ClassA a - with more than one objects as parameters
ClassA a,ClassB b,ClassC c? thank you
- 以一个对象作为参数
ClassA a - 以多个对象作为参数
ClassA a,ClassB b,ClassC c? 谢谢你

You can create the array of objects on the fly:
您可以动态创建对象数组：
method(new Object[] { a, b, c});
Another suggestion is that you change the signature of the method so that it uses java varargs:
另一个建议是更改方法的签名，以便它使用 java varargs：
public static void method(Object... params)
Nice thing is that it is compiled into a method with the same signature as above (Object[] params). But it may be called like method(a)or method(a, b, c).
不错的是，它被编译成一个与上面具有相同签名的方法(Object[] params)。但它可能被称为 likemethod(a)或method(a, b, c)。
