Java 使用重载方法处理异常

public class Main {
   double method(int i) throws Exception {
      return i/0;
   }

   boolean method(boolean b) {
      return !b;
   }

   static double method(int x, double y) throws Exception {
      return x + y ;
   }

   static double method(double x, double y) {
      return x + y - 3;
   }

   public static void main(String[] args) {
      Main mn = new Main();

      try {
         System.out.println(method(10, 20.0));
         System.out.println(method(10.0, 20));
         System.out.println(method(10.0, 20.0));
         System.out.println(mn.method(10));
      } catch (Exception ex) {
         System.out.println("exception occoure: "+ ex);
      }
   }
}
