Which of these is a super class of wrappers Byte and Short wrappers?
Options:

- Float

Solution
The superclass of Byte and Short wrappers in Java is the Number class. Here's the step by step explanation:
-
In Java, all the wrapper classes (Byte, Short, Integer, Long, Float, and Double) are subclasses of the abstract class Number.
-
The Byte, Short, Integer, Long, Float, and Double classes wrap a value of the primitive type byte, short, int, long, float, or double.
-
The Number class is part of the java.lang package. It is the superclass that classes representing numeric values should extend.
-
Therefore, the Number class is the superclass of the Byte and Short wrapper classes.
