java - 将标记化字符串写入文本文件？

Question

我正在尝试将标记化字符串保存到 .txt 文件中...例如，在 Read.txt 中是:

她在海边卖贝壳。

我的程序对其进行了标记，但我似乎无法将标记化的字符串保存到 Write.txt

在 Write.txt 中我得到:

她在海边卖贝壳。

基本上我想将输出保存到Write.txt

任何帮助将不胜感激:D

这是我的输出:

She sells, sea shells, by the sea shore.

[Split by spaces.]

She 
 sells,
 sea shells,
 by
 the
 sea
 shore.

-----------------------------

[Split by commas.]

She sells
 sea shells
 by the sea shore.

以及我当前的代码:

import java.io.*;
import java.util.StringTokenizer;


public class readWriteTokenized{
public static void main( String[] args ){

    String readString;

    try{
        BufferedReader br = new BufferedReader( new FileReader("Read.txt"));

        readString = br.readLine();
        System.out.println("\n" + readString);

        br.close();


        StringTokenizer stnz = new StringTokenizer(readString);

        System.out.println("\n[Split by spaces.]\n");
        while( stnz .hasMoreTokens()){
            System.out.println(stnz .nextToken());
        }


        StringTokenizer stnz2 = new StringTokenizer(readString, ".");

        System.out.println("\n-----------------------------");
        System.out.println("\n\n[Split by comma.]\n");
        while( stnz2.hasMoreTokens()){
            System.out.print(stnz2.nextToken());
        }


        File NewTextFile = new File("C:/TestJava/Write.txt");

        FileWriter fw = new FileWriter(NewTextFile);
        fw.write(readString);
        fw.close();     
    }
    catch (IOException e){
        System.out.println("Catch error!");
    }       
  }
}

Answer 1

您需要write()每个标记，并在其后面附加System.getProperty("line.separator")。示例代码如下:

while( stnz2.hasMoreTokens()){
    fw.write(stnz2.nextToken()+System.getProperty("line.separator"));
}

或者，您可以decorate你的FileWriter与 PrintWriter并使用其 println()格式化方法。
