Well, the array did change. It changed and changed back.

Basically, during the first iteration of the loop, it flipped the first and last elements. And during the last iteration of the loop, it flipped the last and first elements. Anyway, I will let you work out the other iterations of the loop.

but here i do specify which constructor of the superclass to use , because there is only 1 constructor in the superclass in this case, why would it be by default then?
do i must to use the java word "super" to gain access to the superclass constructor?

Java follows the rules of its specification. And there isn't a rule that does what you want, and in the way that you want it -- meaning call the superclass constructor, using the parameters of the subclass constructor parameters, but in a different order. If you want that, you will have to do it yourself -- something like this...

public Apple(String name,String color,String shape)    {       super(name, shape, color);    }

In the Apple class i have a compilation error. ( I uploaded the error with the file )

Why is that?

By default, if your subclass doesn't specify which constructor of the superclass to use, it will try to use the no-args constructor. In this case, your Food class doesn't have a no-args constructor.

Javascript is a weakly typed language -- in contrast to Java which is a strongly typed language.

Strongly typed languages seems to follow the 80/20 rule of development. I mean that it could take 80% of the work to get to prototype, and another 20% to get to production. Weakly typed languages seems to be the reverse. It could only take 20% of the work to get to prototype, and another 80% to get to production.

Startups tend to like weakly typed languages more -- as prototype means funding vs shutting down the company.

ActiveMQ, as with many other  messaging environments, implements producer side flow control. It means that if your producer sends millions of message per second, then it should work. If it wouldn't work, then your producer will be prevented from sending that fast.

Henry

Yeah, definitely not getting that. I guess I need to look into it some more...

Interesting. There is a dashboard...

Running "kubectl proxy" starts and gives access to the dashboard. However, going to the dashboard is just a JSON list of stuff. Is there something that I missed?
