  • 第1题：

    int型public成员变量MAX LENGTH，该值保持为常数100，则定义这个变量的语句是( )。

    A．publicintMAX_LENGTH=100

    B．finalintMAX LENGTH=100

    C．publicconstintMAX_LENGTH=100

    D．publicfinalintMAX_LENGTH=100


    正确答案：D
    解析： 本题考查Java中变量的声明。选项A虽然按照题目要求定义了—个变量，但没有满足保持为常数的要求，该变量可以被改变。选项B没有满足题日要求的public成员变量；选项C与C语言混淆，const是C语言用来定义常值变量的关键字，Java中定义常值变量使用的是final属性，说明该值赋值以后永不改变，所以选项D为正确答案。

    A rectangular fish tank has a base 2 feet wide and 3 feet long. When the tank is partially filled with water, a solid cube with an edge length of 1 foot is placed in the tank. If no overflow of water from the tank is assumed, by how many inches will the level of the water in the tank rise when the cube becomes completely submerged?
    A

    1/6

    B

    1/2

    C

    2

    D

    3

    E

    4


    正确答案： C
    解析：
    When a solid cube with an edge length of 1 foot is placed in the fish tank, it displaces a volume of water that is equal to the volume of the cube, which is 1×1×1 or 1 cubic foot. If h represents the change in the number of feet in the height of the water in the fish tank, then
    Volume of displaced water = 2×3 ×h = 1
    h = 1/6 foot
    Hence, the number of inches the level of the water in the tank will rise is 1/6 ×12 or 2.
