To answer this question, you need to understand the method setLabel and the types of objects it can be used with.
The setLabel method is typically used to set the label or text associated with an object, such as a field or a button.
Let's go through each option to understand which one is correct:
Option A) DoubleField - This option is correct. The setLabel method can be used with a DoubleField object to set the label or text associated with it.
Option B) int - This option is incorrect. The setLabel method cannot be used with an int object as it is a primitive type and does not have any associated label or text.
Option C) TextField - This option is incorrect. The setLabel method cannot be used with a TextField object as it is typically used to set the text content of the field, not the label associated with it.
Option D) String - This option is incorrect. The setLabel method cannot be used with a String object as it is not an object that represents a specific UI element.
The correct answer is Option A) DoubleField. This option is correct because the setLabel method can be used with a DoubleField object to set the label or text associated with it.
