读入文件并将其转换成String的小一段代码

FileReader  fileReader = new FileReader(path);

BufferedReader bufferedReader = new BufferedReader(fileReader);

char input[] = new char[1024];

int n = 0;

StringBuffer sb = new StringBuffer();

while ((n = bufferedReader.read(input)) != -1) {

    sb.append(new String(input, 0, n));

}
