I'm currently learning about class inheritance in my java course and i don't understand when to use the super() call?

I found this example of code where super. variable is used:

If we're using a class method, we don't have an instance to call super with.

Understanding the Context

Fortunately for us, super works even with a type as the second argument.

--- the type can be passed directly to.

As for chaining super::super, as i mentionned in the question, i have still to find an interesting use to that.

For now, i only see it as a hack, but it was worth mentioning, if only for the differences.

Key Insights

In fact, multiple inheritance is the only case where super() is of any use.

I would not recommend using it with classes using linear inheritance, where it's just useless overhead.
