如何在 Java 中的兩個 SwingWorker 類別之間共享資料？

import javax.swing.SwingWorker;
import java.beans.PropertyChangeEvent;
import java.beans.PropertyChangeListener;

public class DataSharingSwingWorker {

    public static void main(String[] args) {
        // Create the SwingWorker instances
        SwingWorker<Integer, Void> lineCounterWorker = new LineCounterWorker();
        SwingWorker<String, Void> divisionWorker = new DivisionWorker();

        // Add a listener to the line counter worker
        lineCounterWorker.addPropertyChangeListener(new PropertyChangeListener() {
            @Override
            public void propertyChange(PropertyChangeEvent evt) {
                if ("result".equals(evt.getPropertyName())) {
                    // Retrieve the line count from the event
                    int lineCount = (int) evt.getNewValue();

                    // Pass the line count to the division worker
                    divisionWorker.passData(lineCount);
                }
            }
        });

        // Execute the workers
        lineCounterWorker.execute();
        divisionWorker.execute();
    }

    private static class LineCounterWorker extends SwingWorker<Integer, Void> {
        @Override
        protected Integer doInBackground() throws Exception {
            // Perform line counting
            return null; // Placeholder for line count
        }

        @Override
        protected void done() {
            firePropertyChange("result", null, get());
        }
    }

    private static class DivisionWorker extends SwingWorker<String, Void> {
        private int lineCount;

        public void passData(int lineCount) {
            this.lineCount = lineCount;
        }

        @Override
        protected String doInBackground() throws Exception {
            // Perform division operation based on the line count
            return null; // Placeholder for division result
        }

        @Override
        protected void done() {
            System.out.println("Division result: " + get());
        }
    }
}
