B
The == operator determines if the contents and type of two separate objects match.
C
The equals（） method returns true only when the contents of two objects match.
D
The class File overrides equals（） to return true if the contents and type of two separate objects match.

正确答案： C,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。
