public static void main(String[] args) {
try {

} catch (SubEx x) {
System.out.println("main() caught SubEx");

System.out.println( "main() caught IOException");
} catch (Exception x) {
System.out.println( "main() caught Exception");
}
}
static void thud() throws IOException {
try {
throw new SubEx();
} catch (SubEx x) {
System.out.println("thud() caught SubEx");
throw new IOException();
////////这儿怎么没有抛给下面的System.out.println( "thud() caught IOException");
} catch (IOException x) {
System.out.println( "thud() caught IOException");
throw new IOException();
} catch (Exception x){
System.out.println( "thud() caught Exception");
}
}
}
结果是：
thud() caught SubEx
main() caught IOException
