Java Frame Drag and drop example program

Dragging requires more physical effort than moving the same pointing device without holding down any buttons. Because of this, a user cannot move as quickly and precisely while dragging. However, drag-and-drop operations have the advantage of thoughtfully chunking together two operands (the object to drag, and the drop location) into a single action. Extended dragging and dropping (as in graphic design) can stress the mousing hand. A design problem appears when the same button selects and drags items. Imprecise movement can cause a dragging when the user just wants to select. Here the JFrame will be used for drag and drop

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;

public class dragdemoex
{
  public static void main(String[] args)
    {
    JFrame frame = new JFrame("Drag and Drop Demo");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setContentPane(new JPanel());
    JTextField textField = new JTextField(25);
    textField.setText("http://codercheck.blogspot.com/");
    frame.add(textField);

    JTextArea textArea = new JTextArea(4, 25);
    textArea.setText("Demonstrating\ndrag and drop");
    frame.getContentPane().add(new JScrollPane(textArea));
    textArea.setDragEnabled(true);
    textField.setDragEnabled(true);
    frame.pack();
    frame.setVisible(true);

   }
}
