Hi all, just a quick question. I have 2 different byte arrays. They are of the same size. How can I put then together in a third byte arrays? Like concatenating 2 string in a third one. Thanks, Alessandro.

I don't think the API provides a method to do this, so you will have to do it by hand. It shouldn't be difficult to create a method to concatenate the two arrays. Think about it for a minute and let us know what you come up with.
p.s. Perhaps the arraycopy() method from the System class will be helpful in implementing this. [ April 22, 2005: Message edited by: Layne Lund ]
This is the small test I ran to check. byte t = "test".getBytes(); byte t1 = "test".getBytes(); byte t2 = new byte; System.arraycopy(t,0,t2,0,4); System.arraycopy(t1,0,t2,4,4); byte t3 = "testtest".getBytes(); if(Arrays.equals(t2,t3)) System.out.println("SAME"); else System.out.println("NO");

You could also make the final thing more general by using the length property of each array:
