Subject: How to test if array element exists?

I'm new to Ruby and just want to test if an array element exists. Here's
a basic code snippet:

array = [0,1,2,3]

if [array[4]].empty?
  puts 'empty'
end
if [array[4]].nil?
  puts 'nil'
end

element 4 does not exist in the array, but neither of the if statements
result in true? what would be an if statement to check that array[4]
does not exist? Thanks
