  • 第1题:

    下列语句能给数组赋值而不使用for循环的是

    A.myArray{[1]="One";[2]="Two";[3]="Three";}

    B.String s[5]=new String[]{"Zero", "One", "Two", "There", "Four"};

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

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


    正确答案:C
    解析:A)、D)语法不正确,B)中s[5]的形式只能通过for循环的格式进行赋值,而不能直接赋值。C)中表达式左侧的“[]”说明现在定义一个数组,不需要指明数组长度,而表达式右侧“[]”在后面直接紧跟初始内容时也是不需要指定数组大小的,数组大小直接由初值长度决定。

  • 第4题:

    下列语句能给数组赋值,而不使用for循环的是

    A.myArray{[1]="One";[2]="Two";[3]="Three";}

    B.String s[5]=new String[] {"Zero","One","Two","Three","Four"};

    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";

    下列给字符串二维数组进行赋值的语句中,错误的是()。

    D.String s[ 2] [2 ] = { { “ One ” , “Two”},{“ Three” , “ Four” } } ;


    String s[ 2] [2 ] = { { “ One ” , “Two”},{“ Three” , “ Four” } } ;
