Which of the following are true statements about the Java wrapper classes (Select all that apply.): Select one or more: a. Objects of these type are immutable b. Objects of these types are mutable c. The wrapper classes do not have no-arg constructors d. The wrapper classes do have no-arg constructors

a. Objects of these type are immutable.

Explanation:

Java wrapper classes are used to convert data into objects. The primitive data is not object and it does not belong to any class. Therefore Java wrapper classes help the user to convert primitive data into object. These objects are immutable and they have no arg constructor.

a variable of array type holds a reference of object

array are commonly used in computer program to organize data so that a related set of values

array are using zero base indexing it start with 0.

all component of array have same type, two different types doesn't use in single array

if array are store 10 quantities its index value varies from 0 to 9.

it stores 1st quantity value in index value 0 and this process will same till index value 9.
