java读取txt文件

写一个比较简答的方法，java读取txt文件，保存在String中

/**
* 读取txt中全部内容，保存在String中
* @param strPath
* @return
*/
public static String GetTextData(String strPath) {
try {
String result = "";
BufferedReader bw = new BufferedReader(new InputStreamReader(
new FileInputStream(strPath), "gbk"));
String line = null;
while ((line = bw.readLine()) != null) {
result = result + line;
}
bw.close();
return result;
} catch (Exception e) {
e.printStackTrace();
return "";
}
}
