Java 程序在几秒后显示帧

使用 Timer() 设置延迟秒数，即在几秒后显示帧 −
Timer tm = new Timer(2000, new ActionListener() {
//
}
以下示例在几秒后显示帧 −
package my;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.Timer;
public class SwingDemo extends JFrame {
private JFrame frame = new JFrame();
public SwingDemo() {
frame.setSize(550, 300);
frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
frame.setVisible(true);
frame.setExtendedState(JFrame.ICONIFIED);
Timer tm = new Timer(2000, new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
java.awt.EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
frame.setExtendedState(JFrame.NORMAL);
}
});
}
});
tm.setRepeats(false);
tm.start();
}
public static void main(String[] args) {
new SwingDemo();
}
}
输出如下，显示 Frame 在 2 秒后出现 −
