Question
Which of the following is true for both Arrays and ArrayLists? (multiple responses are allowed - select all that apply)a.Arrays and ArrayLists are both object types in Javab.Arrays and ArrayLists can be automatically resized during the running of a programc.Arrays and ArrayLists can store object typesd.Arrays and ArrayLists can store primitive typese.None of the above are true
Solution
The correct answers are:
a. Arrays and ArrayLists are both object types in Java c. Arrays and ArrayLists can store object types
Explanation:
a. In Java, both Arrays and ArrayLists are considered as object types. They are not primitive types.
c. Both Arrays and ArrayLists can store object types. For example, you can have an Array of Strings or an ArrayList of Strings.
b. Arrays in Java are of fixed size. Once you declare the size of an Array, it cannot be changed during the running of a program. On the other hand, ArrayLists in Java can be dynamically resized during the running of a program.
d. Arrays can store both primitive types and object types. However, ArrayLists can only store object types, not primitive types. For primitive types, you would need to use their corresponding wrapper classes (like Integer for int, Double for double, etc.) in the ArrayList.
