how to import jframe in java

To import JFrame in Java, you will need to include the following import statement at the beginning of your code:

import javax.swing.JFrame;

JFrame is a class in the Java Swing library, which is a set of graphical user interface (GUI) components for building Java applications. JFrame is a top-level container that provides a window with a title bar, a border, and a content pane. You can use JFrame to create a window that contains other GUI components, such as buttons, labels, text fields, etc.

Here is an example of how you might use JFrame in your code to create a simple window with a title and a button:

import javax.swing.JFrame;
import javax.swing.JButton;

public class JFrameExample {
  public static void main(String[] args) {
    // Create a JFrame
    JFrame frame = new JFrame("My Window");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    // Create a button
    JButton button = new JButton("Click me!");

    // Add the button to the content pane
    frame.add(button);

    // Set the size of the window
    frame.setSize(400, 300);

    // Make the window visible
    frame.setVisible(true);
  }
}

This code creates a JFrame with a title of "My Window", adds a button to the frame, sets the size of the window, and makes it visible. When the user clicks the close button in the title bar, the program will exit.
