This results in: [5, 4, 3, 2, 1] Conclusion In this short guide, we've taken a look at how you can collect and reverse a stream/list in Java 8, using collect() and Collections.reverse() - individually, and together through the collectingAndThen() method. # java# streams Last ...
但是ListIterator有hasPrevious()和previous()方法,可以实现逆向(顺序向前)遍历。Iterator就不可以。 三、ListIterator可以定位当前的索引位置,nextIndex()和previousIndex()可以实现。Iterator 没有此功能。 四、都可实现删除对象,但是ListIterator可以实现对象的修改,set()方法可以实现。Iterator仅能遍历,不能修改。因为Lis...
上述代码中,通过使用return语句,我们将反转排序的Comparator对象返回给调用者。 总结一下,实现Java中的thenComparing reverse方法的步骤如下: 创建一个Comparator对象,用于比较对象的属性。 使用thenComparing方法对多个属性进行排序。 使用reversed方法对排序结果进行反转。 返回反转排序的Comparator对象。 希望这篇文章对刚入行...

第一道题,题目提示非常简单的逆向并提供一个 zip 压缩包,下载本地解压后是一个 exe 可执行文件。尝试用 IDA 反编译,发现 flag 出来了。 感谢善待新人 reverse1 依然给了一个压缩文件,解压后依然是一个 exe 可执行文件,再次尝试用 IDA 反编译,这次没有一眼看到 flag 了,甚至连主函数都没有。于是 Shift +...
