Java reflection: get class of field

Question

I have a method that requires something like Double.class as one of its inputs;

e.g.

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.class of Integer.class etc etc.

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:

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 MyClassWithLotsOfFields but instead java.lang.reflect.Field

any ideas for how to do what I want?

Answer 1

You need Field#getType().

Returns a Class object that identifies the declared type for the field represented by this Field object.

getClass() is a method inherited from Object that returns the type of the object itself.
