J2ME中读取Unicode和UTF-8编码文件

一、读取Unicode文件

 

    /**

 

     * 读取Unicode编码文本文件

 

     * @param resource String - 文件名

 

     * @return String - Unicode文本

 

     */

 

    public static String read_Uni(String resource) {

        byte word_uni[] = new byte[1024];

        String strReturn = null;

        InputStream is;

        try {

            is = instance.getClass().getResourceAsStream(resource);

            is.skip(2);            // 跳过两个字节的文件头

 

            is.read(word_uni);

            is.close();

            StringBuffer stringbuffer = new StringBuffer("");

            for (int j = 0; j < word_uni.length; ) {

                int l = word_uni[j++];

                int h = word_uni[j++];

                char c = (char) ((l & 0xff) | ((h << 8) & 0xff00));

                stringbuffer.append(c);

            }

            strReturn = stringbuffer.toString();

        } catch (IOException ex) {

            System.out.println(ex);

        } finally {

            is = null;

        }

        return strReturn;

}

 

 

二、读取UTF-8文件

 

    /**

 

     * 读取UTF-8编码文本文件

 

     * @param resource String - 文件名

 

     * @return String - UTF-8文本

 

     */

 

    public static String read_UTF(String resource) {

        byte word_utf[] = new byte[1024];

        String strReturn = null;

        InputStream is;

        try {

            is = instance.getClass().getResourceAsStream(resource);

            is.read(word_utf);

            is.close();

            strReturn = new String(word_utf, "UTF-8");

        } catch (IOException ex) {

            System.out.println(ex);

        }

        return strReturn;

   }
