程序员被很多人说不会制造浪漫，只会一天到晚写程序，其实大家对程序员还是不了解，程序员要是浪漫起来，会让很多人羡慕，比如用java代码表白，那用java如何写表白对话框?下面来我们就来给大家讲解一下。
主界面
Frame.java
效果展示：
代码如下：
public class Frame extends JFrame implements ActionListener
{
JButton button;
String message = "LOVE";
String message2 = "YOU";
String message3 = "想念你笑颜如花 将你深深迷恋 ";
String message4 = "想给你日日温暖 将你时时保护 ";
String message5 = "想给你万千繁华 将你浓浓爱恋 ";
String message6 = "想给你刻刻关怀 将你久久拥抱 ";
JLabel messageLabel = new JLabel(message);
JLabel messageLabel2 = new JLabel(message2);
JLabel messageLabel3 = new JLabel(message3);
JLabel messageLabel4 = new JLabel(message4);
JLabel messageLabel5 = new JLabel(message5);
JLabel messageLabel6 = new JLabel(message6);
JLabel messageLabel7 = new JLabel("xxx");
JLabel messageLabel8 = new JLabel("The heart is mine. But it is full of you.");
JLabel messageLabel9 = new JLabel("XXX");
JLabel messageLabel10 = new JLabel("2020");
JLabel messageLabel11 = new JLabel("0214");
JLabel label = new JLabel(new ImageIcon("love.jpg"));
JLabel title = new JLabel("情人节快乐");
Frame()
{
button = new JButton("开始");
button.addActionListener(this);
addComponent();
setTitle("LOVE");
setSize(500, 400);
setVisible(true);
setResizable(false);
setLocationRelativeTo(null);
validate();
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
}
private void addComponent()
{
setLayout(null);
title.setFont(new Font("黑体", Font.BOLD, 16));
title.setForeground(Color.RED);
title.setBounds(200, 10, 100, 20);
add(title);
label.setBounds(-130, -30, 750, 400);
add(label);
button.setFont(new Font("楷体", Font.BOLD, 16));
button.setForeground(Color.GRAY);
button.setBounds(200, 320, 70, 20);
add(button);
Frame()
{
button = new JButton("开始");
button.addActionListener(this);
addComponent();
setTitle("LOVE");
setSize(500, 400);
setVisible(true);
setResizable(false);
setLocationRelativeTo(null);
validate();
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
}
private void addComponent()
{
setLayout(null);
title.setFont(new Font("黑体", Font.BOLD, 16));
title.setForeground(Color.RED);
title.setBounds(200, 10, 100, 20);
add(title);
label.setBounds(-130, -30, 750, 400);
add(label);
button.setFont(new Font("楷体", Font.BOLD, 16));
button.setForeground(Color.GRAY);
button.setBounds(200, 320, 70, 20);
add(button);MyLOVE.java
动画窗口：(此处放截图，运行时效果更好)
public class MyLove extends JFrame implements Runnable
{
/**
*
*/
private static final long serialVersionUID = -2421767851330648008 L;
public MyLove()
{
this.setTitle("LOVE");
this.setBounds(-10, 0, 2000, 2000);
this.setBackground(Color.BLACK);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
}
public void paint(Graphics g)
{
double x, y, r;
Image OffScreen = createImage(2000, 2000);
Graphics drawOffScreen = OffScreen.getGraphics();
for (int i = 0; i < 400; i++)
{
for (int j = 0; j < 400; j++)
{
r = Math.PI / 45 * i * (1 - Math.sin(Math.PI / 45 * j)) * 18;
x = r * Math.cos(Math.PI / 45 * j) * Math.sin(Math.PI / 45 * i) + 900;
y = -r * Math.sin(Math.PI / 45 * j) + 200;
drawOffScreen.setColor(Color.RED);
drawOffScreen.fillOval((int) x, (int) y, 2, 2);
}
g.drawImage(OffScreen, 0, 0, this);
}
}
public void run()
{
while (true)
{
try
{
Thread.sleep(2000);
this.repaint();
}
catch (InterruptedException e)
{
e.printStackTrace();
}
}
}
}这样就完成了java写表白对话框的步骤，如果你也遇到想要表白的人却不知道怎么办，可以参考以上的操作哦!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。
