How to find the length of an array class?

Question

$param = k.chomp.split("\t") 

How can I find the length of $param given that it is an array? actually when I'm writing

puts $param.class 

I got the o/p like Array. Now how do I find the length of this array?

I tried $param.length but it's not working.

Answer 1

Ref Array class

k = "This \t is \t just \t testing" $param=k.chomp.split("\t") array_length= $param.length   #or $param.size puts "length of $param is : #{array_length}" 

o/p

length of $param is : 4 

Answer 2

Try using .size like this:

$param.size
