this could be simiplified a bit with:

if array1.nil? && array2.nil?
  return true
elsif array1.nil? || array2.nil? # if one or the other is nil, but not both
  return false

boolean_value = true
elsif array1 == nil && array2 != nil
boolean_value = false
elsif array1 != nil && array2 == nil
boolean_value = false
elsif array1.length == array2.length
array1.each do |integer|
if integer != array2[i]
boolean_value = false
end
i += 1
end
else boolean_value = false
end
return boolean_value
end
