1.Array.sort(数组,起始位置,结束位置)。这个是升序排序。 2.关于数组的降序实现如下: 利用Collections.reverseOrder()方法: importjava.util.Arrays;importjava.util.Collections;publicclassMain {publicstaticvoidmain(String[] args) {int[] a = {9, 8, 7, 2, 3, 4, 1, 0, 6, 5}; Arrays.sort(a...

14-集合(Collections-reverseOrder) 用迭代器打印出TreeSet集合中的元素: 现在我们想将它倒序打印出来,是不是不再用它默认的比较方式,而是传一个比较器。 比较器: 但是老需要这么写还是很麻烦,我们要想一想,集合框架中是否提供了这样的方法?没有的话我们才需要自己手动来写。
