JAVA时钟代码解释lz这个代码有什么看不懂的 如果这个代码看不懂的话 建议你从基础的开始学习吧
首先可以看到extends JFrame implements ActionListener 关于ActionListener 接口和JFrame 类lz有必要去看看 加入api慢慢研究下吧
int x,y,x0,y0,r,h,olds_x,olds_y,oldm_x,oldm_y,oldh_x,oldh_y,ss,mm,hh,old_m,old_h,ang;
这些东西我也看不懂 因为你的代码不完整
final double RAD=Math.PI/180; 这个应该是算一个弧度吧
super("made by mcj and wdh"); 这句无意义 是父类的代码
setDefaultCloseOperation(3);这个方法是什么？？代码不完整
setSize(300,300);设置窗体大小
setBackground(Color.white);设置背景色
setLocation(300,150); 定位
setResizable(false);不调整大小
setVisible(true);可见
后面的就没有代码了
