getCustomerInfo()方法如下,try中可以捕获三种类型的异常,如果在该方法运行中产生了一个IOException,将会输出什么结果() public void getCustomerInfo() { try { // do something that may cause an Exception } catch (java.io.FileNotFoundException ex) { System.out.print("FileNotFoundException!"); } catch (java.io.IOException ex) { System.out.print("IOException!"); } catch (java.lang.Exception ex) { System.out.print("Exception!"); } }
