How to convert int[] to byte[]

Question

I have an array of integers which represent a RGB image and would like to convert it to a byte array and save it to a file.

What\'s the best way to convert an array

Answer 1

Maybe use this method

byte[] integersToBytes(int[] values)
{
   ByteArrayOutputStream baos = new ByteArrayOutputStream();
   DataOutputStream dos = new DataOutputStream(baos);
   for(int i=0; i < values.length; ++i)
   {
        dos.writeInt(values[i]);
   }

   return baos.toByteArray();
}
