[amp_mcq option1=”.cla” option2=”.class” option3=”.cla” option4=”.vb” correct=”option2″]
The correct answer is B. .class.
A class file is a file that contains the definition of a class in Java. It is a binary file that is compiled from a Java source file. The name of a class file always ends with the extension .class.
The other options are incorrect because they are not the extensions of Java class files.
- .cla is the extension of a class file in Visual Basic.
- .vb is the extension of a source file in Visual Basic.
I hope this helps! Let me know if you have any other questions.
