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.

}
