Which of the following inheritance is not supported by Java?a.Singleb.Multiplec.Hierarchicald.Multilevel

1. Break Down the Problem

The problem is asking to identify which type of inheritance is not supported by Java. The options provided are:

1. Single
2. Multiple
3. Hierarchical
4. Multilevel

2. Relevant Concepts

Java supports the following types of inheritance:

• Single Inheritance: A class inherits from one superclass.
• Multilevel Inheritance: A class inherits from a superclass, which itself inherits from another class.
• Hierarchical Inheritance: Multiple subclasses inherit from a single superclass.

However, Java does not support:

• Multiple Inheritance: A class cannot inherit from more than one superclass, which avoids ambiguity and complexity (e.g., the "diamond problem").

3. Analysis and Detail

Let’s analyze each option:

1. Single: Supported in Java.
2. Multiple: Not supported in Java. A class cannot extend multiple classes.
3. Hierarchical: Supported in Java.
4. Multilevel: Supported in Java.

4. Verify and Summarize

Only "Multiple" inheritance is not supported in Java, which is meant to keep the language simple and avoid potential complications.

Final Answer

b. Multiple inheritance is not supported by Java.
