Convert String type to byte in Java

Question

Is there any way to convert Java String to a byte[] (not the boxed Byte[])?

In trying this:

System.out.println(response.split("\r\n\r\n")[1]);
System.out.println("******");
System.out.println(response.split("\r\n\r\n")[1].getBytes().toString());

and I'm getting separate outputs. Unable to display 1st output as it is a gzip string.

<A Gzip String>
******
[B@38ee9f13

The second is an address. Is there anything I'm doing wrong? I need the result in a byte[] to feed it to gzip decompressor, which is as follows.

String decompressGZIP(byte[] gzip) throws IOException {
    java.util.zip.Inflater inf = new java.util.zip.Inflater();
    java.io.ByteArrayInputStream bytein = new java.io.ByteArrayInputStream(gzip);
    java.util.zip.GZIPInputStream gzin = new java.util.zip.GZIPInputStream(bytein);
    java.io.ByteArrayOutputStream byteout = new java.io.ByteArrayOutputStream();
    int res = 0;
    byte buf[] = new byte[1024];
    while (res >= 0) {
        res = gzin.read(buf, 0, buf.length);
        if (res > 0) {
            byteout.write(buf, 0, res);
        }
    }
    byte uncompressed[] = byteout.toByteArray();
    return (uncompressed.toString());
}

Try using String.getBytes(). It returns a byte[] representing string data. Example:

String data = "sample data";
byte[] byteData = data.getBytes();
