I've created a class which holds a bunch of properties values.
In order to initialize that class, I have to call some static method "configure()" which configures it from an XML ... |

That article doesn't talk about "static" and "dynamic", and I'm not real sure what you mean. So I'm going to guess you mean the difference between knowing the class at compile time and knowing it at run time. // Compile time List mylist = new ArrayList(); // Run time List myList = (List)class.forName( someString ).newInstance(); In the compile time option we ... |

Hi I'm new to Java programming and i've a question regarding how class loader and static keyword works.... When we load the class multiple times in a JVM(is this possible?) what will happen to the static variables state. Will they lose its value? if so then the use of the static keyword is very limited in the sense that preserved static ... |

But, generally all instances are created at run time only right? then why the name static class loading? and even in class.forname() also we are specifying the class name, in that why cant we create an ... |
Hi all, I have a question regarding static and dynamic class loading. I do understand that by writing the new operator, we are statically loading the class and by writing class.forName(), we are dynamically loading the class. My question is that under what conditions do we use dynamic class loading, where loading a class dynamically would make a difference.? Thanks in ... |

It's probably not advisable to use the extension mechanism like this at all. Web servers have common library directories that such libraries are normally placed in. The ext mechanism loads classes with a lower level class loader than may be wise. As to shared static variables it depends what they are used for, but generally sharing static variables across web-apps is ... |
Hi I was wondering if there was any way I could from a textstring containing a path to a classfile make an object of this class, OR run a static method within a user defined class during execution. The class do not need to be "any class", but can implement a desired interface. Thanks. |
