list 集合如何remove重复数据

做个简单笔记：

public class My {

    public My() {
    }
    public static List removeList(List list) {
        for (int i = 0; i < list.size() - 1; i++) {
            for (int j = list.size() - 1; j > i; j--) {
                if (list.get(j).equals(list.get(i))) {

                   list.remove(j);
                }
            }
        }
        return list;
    }
