21. 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!");
- }
- }
复制代码
A IOException! BIOException!Exception! CFileNotFoundException!IOException! DFileNotFoundException!IOException!Exception!
