Which java keyword is used to inherit a class in Java?Question 18Answera.extendsb.derivesc.inheritsd.implements

Break Down the Problem

1. We need to identify the correct keyword in Java used for class inheritance.
2. Option analysis: Understanding the meaning of each option provided.

Relevant Concepts

• In Java, inheritance is a mechanism where one class acquires the properties and behaviors (methods) of another class. The class that inherits is called the subclass (or child class), and the class being inherited from is called the superclass (or parent class).

Analysis and Detail

1. **Option a: ** extends - This keyword is used to create a subclass or derive a new class from an existing class.
2. **Option b: ** derives - This is not a valid keyword in Java.
3. **Option c: ** inherits - This is a term used in general object-oriented discussions but is not a keyword in Java.
4. **Option d: ** implements - This keyword is used to implement interfaces, not for class inheritance.

Verify and Summarize

The keyword used for inheritance in Java is indeed extends. The other options do not represent keywords used for inheritance in the Java programming language.

Final Answer

The correct keyword is a. extends.
