Question
Which of the following are reference types (Mark ALL that apply)
Group of answer choices:
booleanScannerStringint
Solution
To determine which of the following are reference types, we need to understand what reference types are. Reference types are types that store references to objects in memory, rather than storing the actual values themselves.
Looking at the options provided:
- boolean: This is a primitive type, not a reference type.
- Scanner: This is a reference type, as it is a class that represents a scanner object.
- String: This is a reference type, as it is a class that represents a sequence of characters.
- int: This is a primitive type, not a reference type.
Therefore, the reference types in the given options are Scanner and String.
