    C.String s[]=new String[] {"Zero","One","Two","Three","Four"};

    D.String s[]=new String[]= {"Zero","One","Two","Three","Four"};


    正确答案:C
    解析:字符串数组赋初值的方法有两种,一种是如选项C一样初始化。另外一种是先为每个数组元素分配引用空间,再为每个数组元素分配空间并赋初值。例如还可做如下赋值:
      string s[]=new String[5];
      s[0]="Zero";
      s[1]="One";
      s[2]="Two";
      s[3]="Three";
      s[4]="Four";

  • 第19题:

    单选题
    A study by a group of dentists has concluded that regular use of a certain brand of mouthwash is as effective as flossing in preventing gum disease. The mouthwash company has released a television ad suggesting that people who do not like flossing can now rely solely on mouthwash and brushing to maintain good dental health. A leading manufacturer of dental floss brought a lawsuit against the mouthwash company demanding that the advertisement be discontinued on the grounds that it is misleading.  Which of the following, if true, provides the strongest support for the dental floss company’s claim that the advertisement is misleading?
    A

    The dental floss manufacturer is concerned that it will lose market share in the dental health market because the advertisement encourages people to switch from dental floss to mouthwash.

    B

    The dental floss company claims in its own advertisements that brushing and flossing after every meal is the most effective way to maintain good dental health.

    C

    Although mouthwash is an effective deterrent to gum disease, it is less effective than dental floss at removing plaque and preventing cavities between teeth.

    D

    Per usage, mouthwash is three times more expensive than dental floss, if the recommended amounts of both products are used.

    E

    The dentists who conducted the study on the effectiveness of mouthwash in preventing gum disease obtained their funding for the study from a company that manufactures mouthwash.


    正确答案: E
    解析:
    如果广告暗示“people who do not like flossing can now rely solely on mouthwash and brushing to maintain good dental health”但是实际上漱口水并没有牙线的功能,那么便可以说明这则广告具有误导性,故本题应选C项。
