如何在Java中将InputStream转换为字符串？

这是我的版本

public static String readString(InputStream inputStream) throws IOException {    ByteArrayOutputStream into = new ByteArrayOutputStream();    byte[] buf = new byte[4096];    for (int n; 0 < (n = inputStream.read(buf));) {        into.write(buf, 0, n);    }    into.close();    return new String(into.toByteArray(), "UTF-8"); // Or whatever encoding}
