Java reflection: get class of field
提问by Tucker
I have a method that requires something like Double.classas one of its inputs;
我有一个方法需要类似Double.class的输入之一；
e.g.
例如
someOutput = SomeObj.someMethod("parameter",Double.class);
I have another class that has a bunch of fields of different datatypes that I'd like to feed as input to this method in stead of explicitly writing Double.classof Integer.classetc etc.
我有了很多不同的数据类型的字段，我想作为输入养活这个方法取而代之的明确书面另一个类Double.class的Integer.class等等等等。
I know this involves java reflection, but I'm not quite sure how to do what I want. I'm trying something like this but it isn't working:
我知道这涉及 Java 反射，但我不太确定如何做我想做的事。我正在尝试这样的事情，但它不起作用：
for(Field field : Class.forName(MyClassWithLotsOfFields.class.getCanonicalName()).getFields()){
someOutput = SomeObj.someMethod("parameter",field.getClass());
//Do more stuff here...
}
but field.getClass()is not giving me the actual class of the field from MyClassWithLotsOfFieldsbut instead java.lang.reflect.Field
但field.getClass()没有给我该领域的实际类，MyClassWithLotsOfFields而是java.lang.reflect.Field
any ideas for how to do what I want?
关于如何做我想做的任何想法？

You need Field#getType().
你需要Field#getType().
Returns a
Classobject that identifies the declared type for the field represented by thisFieldobject.
返回一个
Class对象，该对象标识此Field对象表示的字段的声明类型。
getClass()is a method inherited from Objectthat returns the type of the object itself.
getClass()是一个继承自的方法，Object它返回对象本身的类型。
