@OldSteve it worked perfectly! I could not find any documentation how to get the size of array using processing, but your help was perfect.I am just wondering why println(val.length()) does not work and outputs an error in processin.
It's just the way the language is put together.
'length' is a variable, 'length()' is a function, each with it's own job to do.
'println(val.length)' will work.
