Question

我必须使用字符串Tokenizer和String方法按字母顺序排列单词。我是Java的初学者所以我只知道像char，比较，布尔操作，if语句，switch语句for，while循环和String Tokenizer等.... 到目前为止，我有这个。

import java.util.*;
public class Alphabetize
{
    // Establish Global Class-State Variables
    static StringTokenizer st;
    public static void main()
    {
        // Input Data
        inData();
        //Variable Assigment
        varAssign();
        //Process Data
        alphaOrder();
        //Output Information
        outPrint();
    }

    public static void inData()
    {
        // Input Data
        String n= "Hailee James Kate Emily Alex Jackie";
        st = new StringTokenizer (Hailee James Kate Emily Alex Jackie);
    }

     public static void varAssign()
    {
        //Process Data

    }

    public static void alphaOrder()
    {
        //Outprint Information
    }

    public static void outPrint()
    {

    }
}

字符串tokenizer类允许应用程序将字符串分解为标记。对于你的情况，你可以使用标记器来分隔单词然后你可以使用一个比较函数，它对一些对象集合强加了一个总排序，你可以找到更多关于引用这些文档[1] [2]

* package whatever; // don't place package name! */

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Alphabetize
{
    public static void main (String[] args) throws java.lang.Exception
    {
        String n= "Hailee James Kate Emily Alex Jackie"; // try to use meaningful identifiers(instead of n use sentence or etc..)
        StringTokenizer tokenizer = new StringTokenizer(n);
        List<String> sortedArrary = new ArrayList<String>();

    while(tokenizer.hasMoreTokens()) {
    sortedArrary.add(tokenizer.nextToken());
}

Collections.sort(sortedArrary, new Comparator<String>() {
    @Override
    public int compare(String o1, String o2) {
        return o1.compareToIgnoreCase(o2);
    }
});
     System.out.println(sortedArrary.toString());
    }
}
