帮忙看段代码好吗？用JBuilder自动生成的，看不大懂

Question

 public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.
                                             getSystemLookAndFeelClassName());
                } catch (Exception exception) {
                    exception.printStackTrace();
                }                new LogicNumberGame();
            }
        });
    }

Answer 1

这个叫做匿名内部类Runnable是一个接口，new Runnable() {...}相当于实例化了一个实现了Runnable接口的类，只是这个类没有名字，所以叫做匿名类，又因为它同时又是内部类，所以完整的名称是“匿名内部类”

Answer 2

new Runnable() { 
            public void run() { 
                try { 
                    UIManager.setLookAndFeel(UIManager. 
                                            getSystemLookAndFeelClassName()); 
                } catch (Exception exception) { 
                    exception.printStackTrace(); 
                }                 new LogicNumberGame(); 
            } 
        }等效于
class TestRunnable implements Runnable{
        public void run() { 
            try { 
                UIManager.setLookAndFeel(UIManager. 
                                        getSystemLookAndFeelClassName());
            }catch (Exception e) {
        exception.printStackTrace();         }
     new LogicNumberGame(); 
      }
 
}
