Thread: Sharing the particular object

Hi all,
I am creating stand alone application in java

i want to know how to share a particular object for all classes through out project

Thank you

It depends on what the shared object is being used for. The Java tutorials provide a good example of using a class variable as a counter, how many bicycles (or something) are in the inventory, but that's a simple int, I believe.

If you want one of your own class objects usable by other classes in the project, you can pass the object to each class' constructor as an instance of the class is created:

SharedObject sharedObject = new SharedObject();
NewObject newObject = NewObject( sharedObject );

Alternatively, you can create a setter method in each of the classes that will share the object that sets the shared object:

public void setSharedObject( SharedObject sharedObject )
{
    this.sharedObject = sharedObject;
}

And there are probably other ways, but these are the most common.

Thank you your post is very useful to me
