To answer this question, we need to understand the hierarchy of the Java Number class and its subclasses.
The Java Number class is an abstract class that serves as the superclass for all numeric wrapper classes in Java, such as Integer, Float, and Double. These wrapper classes extend the Number class and provide specific implementations for various numeric types.
Let's go through each option to determine which one does not extend java.lang.Number:
Option A) Integer - This option is incorrect because the Integer class is a wrapper class that extends the Number class. Therefore, it does extend java.lang.Number.
Option B) Boolean - This option is correct because the Boolean class does not extend the Number class. The Boolean class is a wrapper class for the primitive boolean type, which is not a numeric type.
Option C) Character - This option is correct because the Character class does not extend the Number class. The Character class is a wrapper class for the primitive char type, which is also not a numeric type.
Option D) Short - This option is incorrect because the Short class is a wrapper class that extends the Number class. Therefore, it does extend java.lang.Number.
Therefore, the correct answer is Option B (Boolean) and Option C (Character). These options do not extend java.lang.Number.
