本篇内容主要讲解"Java怎么避免UTF-8的csv文件打开中文出现乱码"，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习"Java怎么避免UTF-8的csv文件打开中文出现乱码"吧!

因为条件有限，只测试了这几个版本，可见utf-16le是更通用的编码格式。下面附上java代码，main方法中采用utf-16le编码，最后调用了utf8编码的方法，最后会输出两种编码格式的csv文件：

import java.io.*;/** * Created by zhaozhi on 15-5-29. */public class TestCSV {  public static String join(String[] strArr, String delim) {    StringBuilder sb = new StringBuilder();    for(String s : strArr) {      sb.append(s);      sb.append(delim);    }    String ret;    if (strArr.length > 1) {      ret = sb.substring(0, sb.length()-1);    }    else {      ret = sb.toString();    }    return ret;  }  public static void main (String[] args) throws Exception {    String[] heads = {"日期", "产品", "订单数"};    String[][] rows = {        {"20150228", "安卓", "23"},        {"20150301", "web", "34"}    };    byte[] bom = {(byte)0xFF, (byte)0xFE};    String fname = "d:\\utf-16le.csv";    BufferedOutputStream bo = new BufferedOutputStream(new FileOutputStream(fname));    bo.write(bom);    bo.write(join(heads, "\t").getBytes("utf-16le"));    bo.write("\n".getBytes("utf-16le"));    for (String[] row : rows) {      bo.write(join(row, "\t").getBytes("utf-16le"));      bo.write("\n".getBytes("utf-16le"));    }    bo.close();    UTF8();  }  public static void UTF8() throws IOException {    String line = "中文,标题,23";    OutputStream os = new FileOutputStream("d:/utf-8.csv");    os.write(239);  // 0xEF    os.write(187);  // 0xBB    os.write(191);  // 0xBF    PrintWriter w = new PrintWriter(new OutputStreamWriter(os, "UTF-8"));    w.print(line);    w.flush();    w.close();  }}

到此，相信大家对"Java怎么避免UTF-8的csv文件打开中文出现乱码"有了更深的了解，不妨来实际操作一番吧！这里是网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习！
