本文从比较排序相关的两个接口(Comparable和Comparator)讲起,并以代码实例的形式,讲解了Array、List、Stream排序的方法,这应该可以覆盖大部分Java排序的使用场景。 对于其它集合类如Set和Map,一样可以进行排序处理,可以将它们转化为Stream然后再进行排序。
package java.util; @FunctionalInterface public interface Comparator<T> { int compare(T o1, T o2); } 它是一个函数式接口,它的compare方法有两个参数,代表进行比较的两个对象。这个接口代表了可以作为某种对象比较的一种法则,或叫一种策略。它的返回值正负代表意义与Comparable接口的方法一样。它的使用通常...

Also, I have used thelambda expressionto implement our Comparators as oppose to theAnonymous classwhich we used earlier. You can see your Comparator implementation has become quite simple and you can write them in just one line. Java Program to sort an ArrayList using Comparator ...

This can be done either sequentially, using the sort() method, or concurrently, using the parallelSort() method introduced in Java SE 8. Parallel sorting of large arrays on multiprocessor systems is faster than sequential array sorting. 排序一个列阵到升序里。 这可以连续地做或者,运用排序() 方法...
