Question

I want execute ExampleSwingWorker1 from Main GUI. Main GUI class compile and doing some jFrame and DB operations and show main app screen to user. And I have another class for store all of my Swingworkers.

public class WorkerClass {
  public class ExampleSwingWorker1 extends SwingWorker<Void, Void> {      
        protected Void doInBackground() throws Exception {
            process1();
            process2();
            process3();
            process4();
            process5();
            process6();
            return null;
        }
        public void done() {
           Toolkit.getDefaultToolkit().beep();
        }
    }

}

Button Action in MainGui Class;

private void buttonRefreshActionPerformed(java.awt.event.ActionEvent evt) {                                              

  WorkerClass.ExampleSwingWorker1 trying = new WorkerClass.ExampleSwingWorker1();   
}

I tried with the above methods for instantiating ExampleSwingWorker1 but it's not possible. But this Oracle Link offer this method for reach inner class.

Solution

You need an instance of WorkerClass first

Workerclass worker = new WorkerClass();
WorkerClass.ExampleSwingWorker1 trying = worker.new ExampleSwingWorker1();
trying.execute();
