    A public member vairable called MAX_LENGTH which is int type， the value of the variable remains constant value 100. Use a short statement to define the variable.（）

     final public int MAX_LENGTH=100；

    D

     public final int MAX_LENGTH=100；


    正确答案： B
    解析： Java中共有变量使用public定义，常量变量使用final，另外注意的是修饰符的顺序，一个最完整的修饰是public static final int varial_a=100;这个顺序不能错，这和c++中也是 不同的。而答案c恰恰错在修饰符的顺序上。
