將一個Tokenized字符串寫入一個文本文件？

Question

我想一個符號化的字符串保存到文本文件... 例，在Read.txt是：

She sells, sea shells, by the sea shore.

我得到了我的程序來標記它，但我似乎無法保存令牌化串入Write.txt

在Write.txt我只是得到：

She sells, sea shells, by the sea shore.

基本上我想要什麼，我輸出保存到Write.txt

任何幫助，將不勝感激：d

這裏是我的輸出：

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. 

而且我目前的代碼：

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

你需要每個令牌write()，附加System.getProperty("line.separator")。示例代碼將是：

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

或者，您可以decorate您FileWriter與PrintWriter並使用其println()方法進行格式化。
