Question

我正在尝试使用netbeans在java中读取tamil文本文件。我得到的输出只是空白的小盒子。我的重点是我需要阅读泰米尔文本文件，每个句子需要拆分为单词。下面给出的代码请仔细检查并给我建议如何获得它。

package javaapplication6;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.lang.Character.UnicodeBlock;

class words {
    private static String[] words;
    private static String[] word;
    public boolean isTamil(String text){  
        boolean result = true;  
        UnicodeBlock tamilBlock = UnicodeBlock.forName("TAMIL");  
        for(int i=0; i<text.length(); i++){  
            UnicodeBlock charBlock = UnicodeBlock.of(text.charAt(i));  
            if(!tamilBlock.equals(charBlock)){  
               result = false;  
            }  
        }  
        return result;  
    }  
    public static void split (String[] query, String[] words) throws IOException {
    String s = "This is a sample sentence.";
    String[] word = s.split("\\s+");

    for (int i = 0; i < words.length; i++) {
    // You may want to check for a non-word character before blindly
    // performing a replacement
    // It may also be necessary to adjust the character class
       word[i] = word[i].replaceAll("", "");
    }   
}

public static void main(String[] args) throws FileNotFoundException, IOException {
        // TODO code application logic hereString fileName="W:/head.txt";
    FileInputStream fstream = new FileInputStream("W:/first.txt");
    BufferedReader br = new BufferedReader(new InputStreamReader(fstream));

    String strLine;

    //Read File Line By Line
    while ((strLine = br.readLine()) != null)   {
    // Print the content on the console
       split(word,words);
       System.out.println (strLine);
    }
    br.close();
}

}

这是因为它的字符编码问题。像IDE这样的Netbeans将使用默认的OS编码，因此它将打印框或其他有趣的字符。

可能的解决方案是将您的角色编码设置为 UTF-8

如果您还没有看到它，请打开项目窗格（Window＆gt; Projects）在树视图单击中右键单击项目名称属性确保菜单项＆＃34;来源＆＃34;在左边是突出显示你应该看到＆＃34;编码：＆＃34;和旁边的选择框。点击确定。

进行。
