Java y） )； } 公共静态void sortStack（）{ 公共堆栈排序（堆栈a）{ a、 排序（新比较器（））； 公共整数比较（整数contID1，整数ContID2）{ 返回contID2.compare（contID1）； } }); 返回a； } } }

我喜欢做的是调用E2.userInput中的'name'，并将其放在Main的输出中

我需要userInput中的所有这些项都可以在Main中看到

接下来我需要关于堆栈排序的帮助，我没有为contID创建rand，但是在创建用户时会这样做。我喜欢在创建贡献者之后进行排序（放入堆栈或链表中，但仍然不确定哪一个是最好的）

提前感谢（是的，这是大学课程）
