java读取中文文件的代码

package com.util;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.HashSet;
import java.util.Set;

public class LoadUserWords {
	public static Set<String> loadUserWords(InputStream input) {
		String line;
		Set<String> myWords = new HashSet<String>();
		try {
			BufferedReader br = new BufferedReader(new InputStreamReader(input,
					"UTF-8"), 1024);
			while ((line = br.readLine()) != null) {
				line = line.trim().toLowerCase();
				myWords.add(line);
			}
			br.close();
		} catch (IOException e) {
			System.err.println("WARNING: cannot open user words list!");
		}
		return myWords;
	}
}

　　这个是java读取中文文件的代码，一般不会出现乱码，不过如果数量级很大的话，部分会是乱码（个人测试）原因未知，

     测试例子，是将一个txt的内容读取出来，放在一个list里并对他们进行排序

package com.dict;

import java.io.InputStream;
import java.util.ArrayList;
import java.util.Collections;
import java.util.HashSet;
import java.util.Iterator;
import java.util.List;
import java.util.Set;

import com.util.LoadUserWords;

public class WordDictionary extends LoadUserWords {
	private static WordDictionary singleInstance;
	private static Set<String> userWords = new HashSet<String>();

	public static Set<String> getUserWords() {
		return userWords;
	}

	public static void setUserWords(Set<String> userWords) {
		WordDictionary.userWords = userWords;
	}

	public static WordDictionary getInstance() {
		if (singleInstance == null) {
			singleInstance = new WordDictionary();
			try {
				singleInstance.read();
			} catch (Exception e) {
			}
		}
		return singleInstance;
	}

	public void read() {
		userWords = loadUserWords((InputStream) this.getClass()
				.getResourceAsStream("a.txt"));
				
				
	}

	public void console() {
		read();
		Set<String> userWords = getUserWords();
		List<String> us = new ArrayList<String>();
		Iterator<String> it = userWords.iterator();
		while (it.hasNext()) {
			us.add(it.next());
		}
		Collections.sort(us);
		for (String string : us) {
			System.out.println(string);
		}
	}

	public static void main(String[] args) {
		new WordDictionary().console();

	}
}
