If i have a array of bytes, then how can i paste a certain amounts of bytes somewhere in between?

edit:

Or can i better convert the byte array to a string array and later convert back to a byte array for saving?

Not sure what you mean by "paste".
Perhaps you should explain what you are trying to do, so we can give more useful information.

I have a change of plan.
Which probably will create a other question later which i will drop here.

http://commons.apache.org/lang/api-release/org/apache/commons/lang/ArrayUtils.html

when i try to use it i get a error "Cannot find anything named "ArrayUtils"".

I probably have to include it but i can't find the command for it.

I tried some things but no luck.

byte[] bToAdd = (byte[]) ArrayUtils.subbarray(b, startIndexInclusive, glitch.startIndex-1);

Note that you have already a number of array utilities with the Arrays class.
And ensure you have installed properly the library, and done the proper import incantation...

I wasn't aware that it was not a default library.

I think i can do what i want with the Arrays class you mentioned.

thanks

~~I solved one thing with the default Arrays class but now i have to combine a few arrays to 1 byte array and for that i need the Lang library.~~

~~I only can't figure out how to get it to work.~~

~~here is the download ( i try 2.6)~~

~~http://commons.apache.org/lang/~~

~~here is the api:~~

~~http://commons.apache.org/lang/api-2.6/index.html~~

~~i did found this so this gave some clue for the include line but also not works (i even added .*; )~~

~~Despite the label of backwards incompatibility, in the vast majority of cases the simple addition of a '3' to an import statement will suffice for your migration.~~

~~Change: import org.apache.commons.lang -> import org.apache.commons.lang3~~

~~I hope someone can trie it for me.~~

edit:

I managed to get the beta version to work, i think 2.6 is broken for processing.

It are .jar files and i add them to my sketch now. Is there a way they can be runned from the library folder?
