Java是如今很流行的编程语言，很多项目开发都会使用java，并且学会java也能做一些浪漫的事情，比如用java写玫瑰花表白代码，那java玫瑰花代码怎么做?下面来我们就来给大家讲解一下。
1. 书写表白语句的frame(渐入功能)
package com.wanju.blessing;
import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.net.URL;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JPanel;
import shen.Panel;
import com.sun.awt.AWTUtilities;
public class ShowFrame extends JFrame
{
public ShowFrame()
{
this.setSize(600, 500);
Dimension screenSize = Toolkit.getDefaultToolkit()
.getScreenSize();
Dimension frameSize = this.getSize();
this.setUndecorated(true);
this.setLocation((screenSize.width - frameSize.width) / 2
, (screenSize.height - frameSize.height) / 2);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container container = this.getContentPane();
// AWTUtilities.setWindowOpaque(this, true);
AWTUtilities.setWindowOpacity(this, 0.01 f);
container.add(new MyPanel(this));
this.setBackground(null);
this.setVisible(true);
new FadeOut(this)
.start();
}
public static void main(String[] args)
{
ShowFrame showFrame = new ShowFrame();
}
}
class MyPanel extends JPanel
{
private Image background;
JFrame frame;
public MyPanel(final JFrame frame)
{
this.frame = frame;
try
{
URL url = Panel.class.getResource("a.jpg");
ImageIcon icon = new ImageIcon(url);
background = icon.getImage();
// background = ImageIO.read(new File("D:\\workspace\\maven\\blessing\\src\\shen\\b.jpg"));
this.addMouseListener(new MouseAdapter()
{
@Override
public void mouseClicked(MouseEvent e)
{
super.mouseClicked(e);
// new FadeOut(MyPanel.this.frame).start();
frame.setVisible(false);
frame.dispose();
}
});
}
catch (Exception e)
{
e.printStackTrace();
}
}
protected void paintComponent(Graphics g)
{
super.paintComponent(g);
g.drawImage(background, 0, 0, 666, 666, null);
g.setColor(Color.red);
g.setFont(new Font("", Font.BOLD, 15));
g.drawString("祝愿宝儿永远幸福的像花儿一样", 60, 280);
}
}
class FadeOut extends Thread
{
private JFrame wnd;
public FadeOut(JFrame wnd)
{
this.wnd = wnd;
}
public void run()
{
try
{
for (int i = 0; i < 50; i++)
{
Thread.sleep(50);
AWTUtilities.setWindowOpacity(wnd, i / 50 f);
}
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
}2.玫瑰花frame
package shen;
import java.awt.EventQueue;
import javax.swing.JFrame;
import com.sun.awt.AWTUtilities;
public class Frame extends JFrame
{
private static final long serialVersionUID = 7517576070147366983 L;
public Frame()
{
setTitle("PNG透明窗体");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setUndecorated(true);
setSize(666, 666);
setLocationRelativeTo(null);
AWTUtilities.setWindowOpaque(this, false);
setContentPane(new Panel(this));
addMouseListener(new MoveWindow(this));
}
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable()
{
@Override
public void run()
{
new Frame()
.setVisible(true);
}
});
}
}3.
package shen;

import shen.Panel.FadeOut;
public class MoveWindow extends MouseAdapter
{
private Point last;
private JFrame frame;
public MoveWindow(JFrame frame)
{
this.frame = frame;
}
public void mousePressed(MouseEvent e)
{
last = e.getLocationOnScreen();
}
public void mouseReleased(MouseEvent e)
{
Point point = e.getLocationOnScreen();
Point fPoint = frame.getLocation();
frame.setLocation(fPoint.x + point.x - last.x, fPoint.y + point.y -
last.y);
last = point;
}

new ShowFrame();
}
}
protected void paintComponent(Graphics g)
{
super.paintComponent(g);
g.drawImage(background, 0, 0, 666, 666, null);
}

这样就完成了java玫瑰花代码，我们可以利用这样的技术对心爱的女孩进行表白，有没有觉得很浪费!如果你也感兴趣的话，可以行动起来!最后大家如果想要了解更多java实例知识，敬请关注奇Q工具网。
