I hope this helps you . Using swing, I want to close my mainGUI with "setVisible(false)", how can I close it when I opened it like this: , It depends the place you wanna do that:
code :
// Hide the window
this.setVisible(false);
// Hide the window
window.setVisible(false);

it helps some times You are calling a function inside your constructor (technically started by the timer thread), which is trying to use the variable execute, which isn't actually assigned until your constructor finishes executing. This is why the value is null, and you are getting an exception.
You could either redesign your class to avoid this sort of condition, or change the reference to refer to SplashScreen.this to refer to the containing instance of the outer class.

I think the issue was by ths following , Initializing an array of objects does not initialize the objects contained in the array and hence you are getting NullPointerException.
Before you try to do this:
code :
cars[0].setMake("Toyota");
cars[0] = new Car(); // or use any other appropriate constructor

Hope this helps The main function is the main thread which loads the UI everytime the view is reloaded. Chances are that you may have some function code specific to your app in the main thread
To free the memory overtime you close the view you can make a function which deallocates all the properties declared in the view Controller. Hope this helps
code :
- (void)dealloc
{
    self.declaredProperty1 = nil;
}

I hope this helps . Without knowing the details of your code, I would suggest you to check the size of args first:
code :
if(args.length> 0) { 
//It depends on the size of the argument you wanna check. 
//Might be args.length > 1 if you wanna make sure at least 2 elements in the args array
   //doSomething
} else {
  //doSomethingElse
}
