3. Enum == static ?    forums.oracle.com

Hi I'm learning Enum... And I have a question: each component of an Enum is static ? For example, in: enum State { INIT, ACTIVE; State() {} } State.INIT and State.ACTIVE can be considered as: static final State INIT = new State(); and static final State ACTIVE = new State(); In this case, a state machine pattern in a StateFullObject can ...

5. Coordinate Planes? Static Sizes? Oh dear.    forums.oracle.com

Greetings, fellow programmers. I come to you today beseeching your help. Most of my attempts to obtain aid from my instructor or colleagues have culminated in a great "RTFM", but the Javadocs only confuse me further. I have no prior experience with GUIs, and so I am left in the dust for this assignment. Basically, my personal assignment in our classwide ...

Hey here is a great help A static variable is intilized when the class is loded. Which means that the static variable will have the same value regardless of the number of objects we create from that class. And the value of that static variable is the same in all objects of that class. Example let say there is a static ...

13. "this" in static?    forums.oracle.com

Good point sabre but is the this keyword really within a static context. You could argue that it is not because you are creating an anonymous 'inner' - nested really I suppose - class. Once that code executes, an independent object will be created - an instance - when it does make sense to use the 'this' keyowrd. Arguably, by using ...

Hi Everyone, I have encountered the following problem and was hoping that someone with a little more Java wisdom than I could troubleshoot it: First of all, I have one java program written entirely in static methods, and another in non-static which I am trying to interface with each other. The problem is this: I don't want to create a new ...

18. static convention    forums.oracle.com

Is this just an rough example or are you really implementing this? If you are implementing this then I wouldn't have leapYear as a static variable. Static variables belong to the class however each instance of Time will need its own instance of leapYear and set to true or false depending on if it is a leap year or not.

19. Why they don't allow static here?    forums.oracle.com

I suspect it's just one of those things that makes implementation a trifle easier while it wouldn't do much for you to allow it. Nested/inner classes don't have static initializers, which might make them cheaper to load. And it doesn't really make any difference if you declare all the static stuff at the outer level. The only overhead is namespace.

20. static refrence do not get garbage collected    forums.oracle.com

There is no such thing as a "static reference" The only references you have to worry about are strong references. (This is the default behaviour for references) Classes are reachable while the class loader is loaded, thus any static reference they have will also be reachable. To release this reference you either have to; - unload the class loader, - make ...
