Answer:
The name of a .java file should <u>always match the name of the class inside.</u>
Explanation:
In Java programming the program written in code editor is first saved with .java extension. The name of this .java file should be same as that of the class declared inside the file.
This .java file is then compiled and converted to .class file which contains the java bytecode. This bytecode can then be executed by java virtual machine(JVM).
However it is not always necessary that name of .java files should be same as that of class inside it. The name should be same only when the class inside is declared as public.
In case it is not declared as public one can name .java file different than the actual class name.
