The JLS says that a widening primitive conversion from float to double may result in "loss of information."

A widening primitive conversion from float to double that is not strictfp may lose information about the overall magnitude of the converted value.

The JLS supports your insightful comment

This restriction makes it easy for a Java compiler to find a named class within a package.


For example, the source code for a public type wet.sprocket.Toad would be found in a file Toad.java in the directory wet/sprocket, and the corresponding object code would be found in the file Toad.class in the same directory.

I also indent my classes as follows:

but isn't this a matter of taste?

Being a left-handed player can give you an advantage if your opponent hasn’t mastered left-handed ball spins, angles etc.

I always taught Nadal (the greatest clay-court tennis player in history) was left-handed. I was surprised the other day to learn that he is right-handed but plays left-handed. At an early age, his uncle taught him to play left-handed in order to give him an advantage.

I'm definitely not saying that Java is a bad language. I'm simply emphasizing the need to adopt best coding practices. Otherwise, horrible things can happen.

It looks horrible indeed. So many horrible things are possible in Java, for example
It's up to the programmer to adopt best coding practices.

You’re right. System.out.println(j) will never be executed; however, the compiler allows unreachable code caused by an if block in order to allow programmers to define "flag variables" for testing and debugging.

The JLS explains why the compiler allows this.

JLS
However, in order to allow the if statement to be used conveniently for "conditional compilation" purposes, the actual rules differ.


JLS
The rationale for this differing treatment is to allow programmers to define "flag variables" such as:

static final boolean DEBUG = false;

and then write code such as:

if (DEBUG) { x=3; }

That isn't true.


I might be wrong since I'm not staff; I'm just a curious, nosy member of this incredibly amazing community. I would assume that a promotion gives you more privileges. I think that a Rancher has more privileges than a Ranch Foreman. For example, a Rancher has the ability to award cows.

I assume that you're referring to Norm's enquiry. You're right, a title or cow does not define you in any way, but we humans are sensitive creatures. In this thread, you talked about how some people get sensitive when something is described as 'Easy' and 'Simple.'  I've seen people on this website absolutely lose it when cows are taken away from them. A £1000 gift has little or no impact on a millionaire's life, but he appreciates it when he receives a £1000 gift for Xmas and he feels offended when he's asked to return the gift.

I agree. It sounds like a demotion and not a promotion. It wasn't long ago when you were announced as a bartender.

Campbell Ritchie wrote:...if you become inactive (or less active), the foreman title can disappear, but the rancher title would remain.


I wonder if a bartender title remains if you become inactive. I'm curious about this because lately, Jayesh A Lalwani has not been so active and has lost his bartender title, but Sharma Ashutosh remains a bartender despite the fact that he has been inactive for the past 4 years.

Thanks for the promotion.

It is true that creating a subclass instance does not create a separate superclass instance as well (as this JLS example shows - Example 12.5-1. Evaluation of Instance Creation).

However, that subclass instance can also be seen as an instance of the superclass.

JLS
The form super.Identifier refers to the field named Identifier of the current object, but with the current object viewed as an instance of the superclass of the current class.
