Q. Globally accessing information

Question

Besides using STATIC to be able to access variables and functions throughout an application that have multiple classes and threads, is there another method that could be used to handle this.
Maybe something involving threads?
Any help would be appreciated.

Answer 1

I don't think threads are where you want to go. If what you want is to have all the parts of your program have access to the same instance of a single class then you could write the class as a "singleton" design pattern.
Is that what you need?
public SingletonClass {
   private static SingletonClass theOnlyOne = null;
   // this is private so you can't create one of these
   private SingletonClass (){
      // initialization goes here
   // use this method to get the one and only instance of this class
   public static SingletonClass getInstance() {
      if (theOnlyOne == null) {
         theOnlyOne = new SingletonClass ();
       return theOnlyOne;
}The code above will one create one instance of "SingletonClass" the first time you call SingletonClass.getInstance(). From then on every other call to SingletonClass.getInstance() will give you the same instance.
