What is the primary advantage of classes over primitive data types?

• Classes use less memory

• Classes process data faster

• Classes provide access to special attributes and behaviors

• Classes can only store numerical values

What is the main purpose of wrapper classes in Java?

• To make programs run faster

• To reduce memory usage
