Is the member function virtual by default

Is member function virtual by default in scala? Is this different from Java in this matter?

When a method is overridden, you must explicitly specify this, but there is no "virtual" one.

Yes.

Is this different from Java in this matter?

No, in Java methods are also virtual unless explicitly defined as final .

However, Java differs from Scala in that Java does not require (or does not have) the override keyword to override methods - it has an @override annotation, although (since Java 1.5) it gives a warning when overriding a method without this annotation.

No. However, it is different from C ++ or C #.

Whether this is a good or bad idea is very reasoned.
