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!");

}
A.IOException!

整个看下来还是感觉迷迷糊糊的
