    D

    Local variables must be initialized before they are used.


    正确答案： B,D
    解析： 类中有几种变量，分别是：局部变量（英文可以为：local/automatic/temporary/stack variable）是定义在方法里的变量；实例变量（英文为：instance variable）是在方法外而在类声明内定义的变量，有时也叫成员变量；类变量（英文为：class variable）是用关键字static声明的实例变量，他们的生存期分别是：局部变量在定义该变量的方法被调用时被创建，而在该方法退出后被撤销；实例变量在使用new Xxxx()创建该类的实例时被创建，而其生存期和该类的实例对象的生存期相同；类变量在该类被加载时被创建，不一定要用new Xxxx()创建，所有该类的实例对象共享该类变量，其生存期是类的生存期。任何变量在使用前都必须初始化,但是需要指出的是局部变量必须显式初始化，而实例变量不必，原始类型的实例变量在该类的构造方法被调用时为它分配的缺省的值，整型是0，布尔型是false，而浮点型是0.0f，引用类型（类类型）的实例变量的缺省值是null（没有进行实际的初始化，对它的使用将引起NullPointException），类变量的规则和实例变量一样，不同的是类变量的初始化是在类被加载时。

    正确答案： A,D
    解析： 严格来说这个问题的答案是不确定的，因为equals()方法是可以被重载的，但是按照java语言的本意来说：如果没有重写（override）新类的equals()，则该方法和 == 操作符一样在两个变量指向同一对象时返回真，但是java推荐的是使用equals()方法来判断两个对象的内容是否一样，就像String类的equals()方法所做的那样：判定两个String对象的内容是否相同，而==操作符返回true的唯一条件是两个变量指向同一对象。从这个意义上来说选择给定的答案。从更严格的意义来说正确答案应该只有D。
