This tutorial will teach you how to create a drag and drop program in two textfields in java. So, now let's start this tutorial! 1. Open JCreator or NetBeans and make a java program with a file name of dragDrop.java. 2. Import the following package library:
  1. import javax.swing.*; //used to access JFrame and JTextArea class
  2. import java.awt.*; //use to access the GridLayout class
3. We will initialize variables in our Main, variable frame as JFrame, and variable textfield1 and textfield2 as JTextField.
  1.     JFrame frame = new JFrame("Drag and Drop");
  2.     JTextField textField1 = new JTextField(50);
  3.     JTextField textField2 = new JTextField(50);
4. We will have a text for the two textfields using the setText method.
  1.     textField1.setText("Drag this text to the textfield below.");
  2.     textField2.setText("You can also drag this text above.");
To have a drag and drop between the two textfields, we will use the setDragEnabled method returns to True.
  1.     textField2.setDragEnabled(true);
  2.     textField1.setDragEnabled(true);
5. Now, we will have its layout into Grid Layout using the setLayout method of the frame.
  1. frame.getContentPane().setLayout(new GridLayout(0,1));
Add all the textfields to the frame using the add method.
  1.     frame.getContentPane().add(textField2);
  2.     frame.getContentPane().add(textField1);
Lastly, pack the frame, set visibility to true, and the close operation of the frame. Have this code below:
  1.     frame.pack();
  2.     frame.setVisible(true);
  3.     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Output: output Here's the full code of this tutorial:
  1. import javax.swing.*; //used to access JFrame and JTextArea class
  2. import java.awt.*; //use to access the GridLayout class
  3. public class dragDrop {
  4.   public static void main(String[] args) {
  5.     JFrame frame = new JFrame("Drag and Drop");
  6.     JTextField textField1 = new JTextField(50);
  7.     JTextField textField2 = new JTextField(50);
  8.    
  9.     textField1.setText("Drag this text to the textfield below.");
  10.     textField2.setText("You can also drag this text above.");
  11.    
  12.     textField2.setDragEnabled(true);
  13.     textField1.setDragEnabled(true);
  14.     frame.getContentPane().setLayout(new GridLayout(0,1));
  15.     frame.getContentPane().add(textField2);
  16.     frame.getContentPane().add(textField1);
  17.    
  18.     frame.pack();
  19.     frame.setVisible(true);
  20.     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  21.    
  22.   }
  23. }
