怎么读取文件的内容为string

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();    }
