Given the following statement: huey.setDouble(8.0*32.2+1.0); What must be the data type of huey?
-
TextField
-
DoubleField
-
IntField
-
double
The method setDouble() indicates that huey must be a DoubleField object, which has a method to set its double value. A primitive double type would not have methods - only objects do. TextField and IntField would not have setDouble methods.
To determine the data type of huey, let's analyze the given statement: huey.setDouble(8.0*32.2+1.0).
In this statement, the setDouble() method is being called on huey, which suggests that huey is an object that has a setDouble() method.
By looking at the argument passed to setDouble(), which is 8.0*32.2+1.0, we can see that it involves floating-point numbers (numbers with decimal places) and arithmetic operations.
Based on this information, we can conclude that huey must be an object of the DoubleField type.
Therefore, the correct answer is B) DoubleField.
