Drag and Drop in Java

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:

import javax.swing.*; //used to access JFrame and JTextArea class
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.

    JFrame frame = new JFrame("Drag and Drop"); 
    JTextField textField1 = new JTextField(50);
    JTextField textField2 = new JTextField(50);

4. We will have a text for the two textfields using the setText method.

    textField1.setText("Drag this text to the textfield below.");
    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.

    textField2.setDragEnabled(true);
    textField1.setDragEnabled(true);

5. Now, we will have its layout into Grid Layout using the setLayout method of the frame.

frame.getContentPane().setLayout(new GridLayout(0,1));

Add all the textfields to the frame using the add method.

    frame.getContentPane().add(textField2);
    frame.getContentPane().add(textField1);

Lastly, pack the frame, set visibility to true, and the close operation of the frame. Have this code below:

    frame.pack();
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

Output: output

Here's the full code of this tutorial:

import javax.swing.*; //used to access JFrame and JTextArea class
import java.awt.*; //use to access the GridLayout class
public class dragDrop {
  public static void main(String[] args) {
    JFrame frame = new JFrame("Drag and Drop"); 
    JTextField textField1 = new JTextField(50);
    JTextField textField2 = new JTextField(50);
 
    textField1.setText("Drag this text to the textfield below.");
    textField2.setText("You can also drag this text above.");
 
    textField2.setDragEnabled(true);
    textField1.setDragEnabled(true);
    frame.getContentPane().setLayout(new GridLayout(0,1));
    frame.getContentPane().add(textField2);
    frame.getContentPane().add(textField1);
 
    frame.pack();
    frame.setVisible(true);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
  }
}
