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!);
}
}
③
FileNotFoundException!IOException!
④
FileNotFoundException!IOException!Exception!
