对字符串中的某些单词进行排序

Question

假设有一个文件：

Virginia Tyler Taylor Wilson
Ohio Grant Hayes Garfield Harrison_B McKinley Taft Harding
Massachusetts Kennedy Bush_GHW
New_York VanBuren Fillmore Roosevelt_T Roosevelt_F

我需要按顺序排序，下面是我的代码：

TreeMap<String, String> map = new TreeMap<String, String>();
while (infile1.ready()){
String line = infile1.readLine();
String s = line.substring(0, line.indexOf(" "));
String p = line.substring(line.indexOf(" "));

map.put(s, p);
}

for (String p : map.keySet()){
System.out.println(p + " " + map.get(p));
}

我的输出是：

Massachusetts  Kennedy Bush_GHW
New_York  VanBuren Fillmore Roosevelt_T Roosevelt_F
Ohio  Grant Hayes Garfield Harrison_B McKinley Taft Harding
Virginia  Tyler Taylor Wilson

预期输出为：

Massachusetts **Bush_GHW Kennedy**
New_York **Fillmore Roosevelt_F Roosevelt_T VanBuren**
Ohio **Garfield Grant Harding Harrison_B Hayes McKinley Taft**
Virginia **Taylor Tyler Wilson**

唯一的区别是值的顺序，我在预期的输出中加粗它。 有没有一种快速的方法来排序String p并将其放入地图？

Answer 1

你可以写短文

Arrays.sort(line.substring(line.indexOf(" ")).split(" "));

Answer 2

试试这个

String[] ps = line.substring(line.indexOf(" ")).split(" ");
Arrays.sort(ps);

然后尝试将ps与p结合使用＆＃34; ＆＃34 ;;

Answer 3

Massachusetts **Bush_GHW Kennedy**
New_York **Fillmore Roosevelt_F Roosevelt_T VanBuren**
Ohio **Garfield Grant Harding Harrison_B Hayes McKinley Taft**
Virginia **Taylor Tyler Wilson**

In your above expected output how Bush Comes after mass..
So please explore output correctly.
