我如何按字母顺序排序？ [英] How Can I Sort Alphabetically?

问题描述

好吧基本上我有一个会员俱乐部满是会员，当我想要取回他们所有的名字

i使用这个代码，但我真正想做的是按字母顺序将它们全部带回来，我不能使用java lib的帮助我必须使用我自己的排序方法。在任何人向我发送链接到java docs之前我已经尝试过但无法弄明白。

OK basically i have a members club full of members and when i want to get all their names back
i use this code but what i really want to do is get them all back alphabetically, and i cant use the help of a java lib i have to use my own sort method. And before any one sends me links to java docs i have already tried but cannot figure it out.

/**
 * List names.
 */
public void listNames() {
    for (int i = 0; i < members.size(); i++) {
        Member member = members.get(i);
        member.getName();
        StdOut.println(i + ":" + member.getName());
    }
}
          }

推荐答案

你应该可以采用复制它为家庭作业时的代码。



您的老师可以看到它是您的代码还是其他代码。



请检查API：

http://docs.oracle.com/javase/7/docs/api/java/util/ArrayList.html#toArray() [ ^ ]

You should be able to adopt the code when you copy it for the homework.

Your teacher can see if it's your code or another ones.

Please check the API:
http://docs.oracle.com/javase/7/docs/api/java/util/ArrayList.html#toArray()[^]

试试这个

Try this

public static void sortStringExchange( String  x [ ] ){
 
             Arrays.sort(x, new Comparator<string>() {
 
                @Override
                public int compare(String s1, String s2) {
 
                return s1.compareTo(s2);
 
           }
});
}

试试heapsort http://en.wikipedia.org/wiki/Heapsort [ ^ ] http://codereview.stackexchange.com/questions/32606/implementation- of-heap-sort [ ^ ]



希望这会有所帮助:)
