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)

            .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

    JFrame frame;
    public MyPanel(final JFrame frame)
    {
        this.frame = frame;
        try

                    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();
        }
    }
}
