如何從隨機數中排序值？

[英]How to sort the value from random numbers?

 原文  2015-09-29 09:17:53  7   3    java

問題描述

for(x1 = 0; x1 < 26; x1++)
{
    index = (int)Math.round(Math.random() * ((arrnamex.size())-1) + 0);
    x=arrnamex.get(index);
    //x is for choosing a case
    y=arrnamey.get(index);
    //same with y
    arrnamex.remove(index);

    arrnamey.remove(index);
    posX.add(x);
    posY.add(y);
}

我唯一的問題是如何從隨機數升序排序

3 個解決方案

將您的隨機數添加到列表中。

排序列表。

解決方案2

 SortedSet<Integer> set = new TreeSet<Integer>();

現在添加要set隨機數。

我的程序太長了..但這是我真正需要的，所以我希望你能理解..（這不是整個程序，但我希望你仍然可以幫助我）
