  • 第1题:

    下面程序输出的结果是什么? ( ) public class Quiz2 { public static void main(String args[]) { try {throw new MyException(); }catch(Exception e) { System.out.println("It's caught!"); }finally{ System.out.println("It's finally caught!"); } } } class MyException extends Exception{}

    A.It's finally caught!

    B.It's caught!

    C.It's caught!/It's finally caught!

    D.无输出


    正确答案:C
    解析:本题是对异常处理基本知识的考查。本程序中创建了一个异常类MyException,它的祖先类是Exception。在程序中,程序先发出异常MyException,下面是catch捕获异常,但是catch列表中并没有与之对应的MyExcepfion,但是有一个Exception,它是MyException的祖先类。如果有多种异常需要捕获,在安排catch语句的顺序时要注意,应该首先捕获最特殊的类,然后逐渐一般化。例如,IOExcepfion类是FileNotFoundException类的父类;就应该首先捕获FileNotFoundException异常,然后捕获IOExcepfion异常。所以运行结果是It'scaught!/It'sfinallycaught!

    A.In Situation l

    B.In Situation

    C.with Catch

    D.int iArray l


    正确答案:A
    A。【解析】本题考查考生阅读Java程序的能力。题目程序看似复杂,但流程非常简单。程序的public类是thtowsExeeption,类中定义了Proe(intsel)方法。程序入口是main方法,使用try-catch-finally来捕获ArithmeticExeeption和ArrayIndexOutOfBoundsExeeption异常,这两个异常是关于算术异常或数组索引越界的异常。执行Proe(0)时,输出InSituation0和noExceptioncaught两条信息;执行Proc(1)时,输出InSituationl和inProcfinally两条信息。整个程序并未发生异常。
