This interface imposes a total ordering on the objects of each class that implements it. This ordering is referred to as the class'snatural ordering, and the class'scompareTomethod is referred to as itsnatural comparison method. 此接口对实现它的每个类的对象强加一个默认排序。这种排序被称为类...

【编程基础】Java Comparator接口的使用 java 在实际编程中我们经常会用到集合或者数组,有的时候你需要对这个集合中的元素就行排序,那这个时候就用到了Comparator接口,先看一下接口的原型: public interface Comparator<T> { /** * Compares the two specified objects to determine their relative ordering. The ord...
(obj)取得这个默认的hash code;这种机制保证了不互相 == 的对象,其hash code一定不相同(As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects。但这句话也不完全正确,默认hash code也是存在相同的可能的,参见:http://bugs.sun....
