How to gzip string in java. How to compress string to byte array.

MainActivity.java

    private byte[] compress(String data) throws IOException {
        ByteArrayOutputStream bos = new ByteArrayOutputStream(data.length());
        GZIPOutputStream gzip = new GZIPOutputStream(bos);
        gzip.write(data.getBytes());
        gzip.close();
        byte[] compressed = bos.toByteArray();
        bos.close();
        return compressed;
    }

    private String decompress(byte[] compressed) throws IOException {
        ByteArrayInputStream bis;
        bis = new ByteArrayInputStream(compressed);
        GZIPInputStream gis;
        gis = new GZIPInputStream(bis);
        BufferedReader br;
        br = new BufferedReader(new InputStreamReader(gis, "UTF-8"));
        StringBuilder sb;
        sb = new StringBuilder();
        String line;
        while ((line = br.readLine()) != null) {
            sb.append(line);
        }
        br.close();
        gis.close();
        bis.close();
        return sb.toString();
    }
