Swing - Can a variable be referenced by another variable?

Good day,

Say I have thisNum=1 is there a way I can reference JProgress1Bar by JProgress+thisNum+Bar ?

I've looked a around a lot and have drawn a blank.

Any help appreciated!

No. It sounds like you're gong down a "scripty" route and trying to program based on the name of a variable. Don't. If you need to associate names to objects, use a Map.

If you have some logic to control the behavior of the bar, I suggest you place that code in a class that also has a reference to the bar, something like this maybe:

Code:

class BarControl
{
   private JProgressBar bar;

   public BarControl(JProgressBar bar)
   {
      this.bar = bar;
   }

   public void doBarLogic()
   {
      ...
   }
}
