Question

The Add method has one parameter - an Object variable that holds the item to be added to the collection. What is the parameter of the Add method?

1) Object variable
2) Collection
3) Item
4) Method

Answer 1

The parameter of the Add method is the object variable. Parameters act as placeholders in a method's definition for the values passed when the method is called.

Step-by-step explanation:

The parameter of the Add method is the object variable. When a method in a programming language is designed to add an item to a collection, the item that needs to be added is passed as an argument to the Add method. In this case, since the question specifies that the Add method has one parameter that is an object variable, which holds the item to be added, the correct answer is the object variable.

Parameters are the variables listed as part of a method's definition and act as placeholders for the values that are passed into the method when it is called. The collection is not a parameter but rather the entity to which the item is being added. The item is what is being represented by the object variable, and the method is the function, 'Add', itself, which utilizes the parameter to perform an operation.
