    阅读下列代码 public class Test2005{ public static void main(String args[]){ String s="Test"; switch(s){ case"Java":System.out.print("Java"); break; case"Language":System.out.print("Lan- guage"); break; case"Test":System.out.print("Test"); break; } } } 其运行结果是( )。

    A.Java

    B.Language

    C.Test

    D.编译时出错


    正确答案:D
    D。【解析】本题考查switch语句的用法。switch语句是多分支语句,即根据表达式的值来执行多个操作中的一个。在switch语句中,”表达式”的返回值类型必须是这几种类型之一:int、byte、char、short。本题中,switch的表达式s是一个字符串Strin9类型的值,它不是int、byte、char、short中的任意一个。因此表达式s的类型不对,编译时出错。

    正确答案: B
    解析:
    继承是面向对象编程的一个主要优点之一,它对如何设计Java类有着直接的影响。该程序首先编写了一个Shape的类,然后又编写一个类Circle去继承Shape类。由于子类拥有父类所有的属性和方法,所以输出的是ShapeCircle。
