I'm working with Doxygen at the workplace and am having a problem with the Java code. With the EXTRACT_ALL=NO, EXTRACT_PRIVATE=NO, EXTRACT_STATIC=NO, EXTRACT_LOCAL_CLASSES=NO, and EXTRACT_LOCAL_METHODS=NO, the output still includes static members that ... |

1.How can the java programme work with a non-static variable inside static main function? your are limited in the use of variable for instace variable only It is quite normal because when you declare something static this belong to the class and not to one of the instance of a class. So you can use local variable inside your static methode ... |
why is this? is it because of the method's life span? what i mean is if the method is destroyed after use, but a variable local to it is declared as static then the compiler throws an error? i guess i am not getting why this matters with methods, even though i understand it from a scope point of view. thank ... |

I dont understand , why java doesn't support these 2 cases CASE 1: Overriding static function of super class . Here is the example : ----------------------------------------------------------------- class A { static void fun1() { } }; class B extends A { void fun1() { } }; --------------------------------------------------------------------- CASE 2: Overriding non-static function of super class as static function -------------------------------------------------------------------------- class A { ... |
The easiest way to find out is to write a small program and try to compile it. In Java you cannot create static variables inside a method, like you can in C or C++ inside a function. Also, you can't create a static member variable in a non-static inner class. You can only create a static member variable in a top-level ... |
Originally posted by biny panackal: which i am changing here. All your accesses of "i" are accessing the instance field, via a reference to an object of class "b". Therefore, they are all legal. Your method-local variable "i" hides the instance field "i". So, if your code in main() accessed "i" without reference to an object of class "b", it would ... |
Hi , I was going through the static methods. It says that for static variables, there is only one copy for the entire class. Is it the same with the methods as well? I mean that if a method is defined to be static , there is only one copy of it in the memory no matter how many objects of ... |
Hi all, I know that static functions are class wide, and only a single copy exists for a static function for all the objects instantiated. A static function can also be used without instantiating other objects of the class in which it is declared. Now what about functions that are declared class wide? What is the difference? I know that seperate ... |

Well I have a command line app; and it has a public static void main. Now, I made a function that writes to a file, and tried calling it from the main section, and it got mad saying I can't call it from static context. Anyway to allow it to be called from both static and non static contexts? |
static method can be overridden. but it's not a best practice. it is not recommended until the program demands. But most probably you will never find that kind of situation where you need to override a static method. and remember in java we use "method" in place of "function". Observe the coding conventions.

Static methods are used to mention the compiler that the method is not binded to any instance of the class but shared by all the objects of that class. For instance, consider Book is a class and getPrice() is a non-static method. so getPrice() should be called on the object, like myBook.getPrice(). But if it has to designed as static then ... |
I tried instantiating objects within static functions as follows: It gives error: If someone can explain an alternate way of doing things, I would appreciate: public class C { /** * @param args */ public static void main(String[] args) { Y.Fn1(); } } public class X { public void Fn2(){ int b=2; System.out.println("hello"); } } public class Y { public static ... |

I have a helper class that pretty much just a collections of methods for setting up gui controls and formatting text.
