Select the correct answerWhich of these is a super class of all exceptional type classes?OptionsStringThrowableCacheableRuntimeExceptions

Breakdown of the Problem

1. Identify the options given: String, Throwable, Cacheable, and RuntimeExceptions.
2. Determine what is meant by "super class" in the context of exceptional types in programming (particularly in Java).

Relevant Concepts

1. In Java, all exceptions are derived from the Throwable class.
2. The Throwable class has two primary subclasses: Error and Exception.
3. RuntimeExceptions are a subset of exceptions, not a super class.
4. String and Cacheable are not related to exception handling in Java.

Analysis and Detail

• Throwable: This is the base class for all errors and exceptions in Java. Therefore, it is the most general type for exceptional classes.
• RuntimeExceptions: These are exceptions that can occur during the program's operation but are not checked at compile-time; they belong to the exception hierarchy but are not super classes themselves.
• String and Cacheable do not serve any role in the exception hierarchy.

Verify and Summarize

The Throwable class encompasses all exceptions and errors in Java, making it the super class of all exceptional type classes. Among the options identified, it is the only one that fulfills the requirements of being a super class.

Final Answer

Throwable is the super class of all exceptional type classes.
