如何读取文件的内容为string

这儿提供一个java方法:

    public String readFileAsString(String filePath)
            throws java.io.IOException {
        StringBuffer fileData = new StringBuffer("");
        BufferedReader reader = new BufferedReader(
                new FileReader(filePath));
        char[] buf = new char[1024];
        int numRead = 0;
        while ((numRead = reader.read(buf)) != -1) {
            String readData = String.valueOf(buf, 0, numRead);
            fileData.append(readData);
            buf = new char[1024];
        }
        reader.close();
        return fileData.toString();
    }
