Use Java to write beautiful love patterns to make programming fun

Play with Java code and easily write beautiful love patterns

In the field of programming, the Java language has always been favored by developers for its powerful functions and flexible features. favorite. In addition to being used in daily software development and system design, Java can also be used to write a variety of interesting patterns. Among them, the heart pattern is a pattern that makes people feel warm and romantic. The following will use specific code examples to show how to use Java to write an exquisite heart pattern.

First, we need to import the graphics library in Java. Here we choose to use Java's AWT (Abstract Window Toolkit) library. The AWT library provides a series of classes and methods for drawing graphics, which can easily realize the drawing function.

Next, we need to define a class that inherits from JFrame. This class will serve as our main window and draw graphics on it. In this class, we need to override the paint method to perform graphic drawing operations. The following is a simple code example:

import java.awt.Color;
import java.awt.Graphics;
import import java.awt.Graphics2D;;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class HeartPattern extends JFrame {

    public HeartPattern() {
        setSize(600, 600);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        add(new DrawingPanel());
    }

    public static void main(String[] args) {
        HeartPattern heartPattern = new HeartPattern();
        heartPattern.setVisible(true);
    }

    private class DrawingPanel extends JPanel {

        @Override
        protected void paintComponent(Graphics g) {
            super.paintComponent(g);

            Graphics2D g2d = (Graphics2D) g;
            g2d.setColor(Color.RED);

            int width = getWidth();
            int height = getHeight();

            int cx = width / 2;
            int cy = height / 2;

            int size = Math.min(width, height) / 3;

            g2d.fillArc(cx - size / 2, cy - size, size, size, 0, 180);
            g2d.fillArc(cx, cy - size, size / 2, size, 0, 180);
            g2d.fillRect(cx - size / 2, cy - size, size, size);
        }
    }
}

In the above code, we first create a HeartPattern class inherited from JFrame, and set the window size and closing method in its construction method. Next, we define a DrawingPanel class inherited from JPanel, and perform specific graphic drawing operations in the paintComponent method of this class.

In the paintComponent method, we first obtain the width and height of the current window, and calculate the size and position of the heart pattern. Then, we use the Graphics2D class to set the color, and use the fillArc and fillRect methods to draw two arcs and a rectangle of the love pattern, completing the drawing of the entire pattern.

Finally, we create the HeartPattern object in the main method and set it to visible.

By running the above code, a beautiful heart pattern can be displayed in the Java graphical interface. By modifying the parameters in the code, we can also adjust the size and position of the pattern to further enrich the effect of the pattern.

In the world of programming, creation goes beyond software development. By flexibly using various features and library functions of the Java language, we can write a variety of interesting patterns and works of art. I hope this heart pattern example can inspire your creativity and allow you to have fun on your programming journey!
