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：

She sells, sea shells, by the sea shore.

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

在Write.txt 我刚刚得到：

She sells, sea shells, by the sea shore.

基本上我想将输出的内容保存到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.

还有我当前的代码：

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

您需要为每个令牌添加write()，并附加System.getProperty("line.separator")。示例代码将是：

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

或者，您可以使用PrintWriter decorate 您的FileWriter 并使用其println() 方法进行格式化。
