You can probably use ByteBuffer: 

byte[] byte = ByteBuffer.allocate(4).putInt(1695609641).array();

for (byte a : byte) {
   System.out.format("0x%x ", a);
}

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

Example:

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