Is it possible to minimize data type(int) size ?

If you need this level of control over the layout of your packet, the packet must be defined as an array of bytes. When you want to put a 24-bit number in the packet, you split the number us list this:

int num42=0x00123456;

byte[] packet=new byte[1024];

byte[n+4]=(byte)((num24>>0)&0xff);

byte[n+5]=(byte)((num24>>8)&0xff);

byte[n+6]=(byte)((num24>>16)&0xff);

noe the packet will look lik: 0,0,0,0,0x56,0x34,0x12,0,0,0,0,0.....

Hope this helps.
