Else without rescue is useless - ruby

Question

I'm having a problem with my code, and can't seem to figure out what I need to change. Here are my three files, and at the bottom is the error that I am getting.
require './PokerHand'
require "./Constants"
require 'minitest/autorun'
class TestClass < MiniTest::Test
include Constants
def test_1
arr1 = [Card.new(2, "S"), Card.new(3, "S"),
Card.new(4, "S"), Card.new(5, "S"),
Card.new(6, "S")]
ph1 = PokerHand.new(arr1)
ph1.classify
assert_equal STRAIGHT_FLUSH, ph1.hand_type
end
def test_2
arr2 = [Card.new(9, "C"), Card.new(9, "S"),
Card.new(9, "H"), Card.new(9, "D"),
Card.new(11, "S")]
ph2 = PokerHand.new(arr2)
ph2.classify
assert_equal FOUR_OF_A_KIND, ph2.hand_type
end
def test_3
arr3 = [Card.new(4, "C"), Card.new(9, "S"),
Card.new(9, "H"), Card.new(9, "D"),
Card.new(9, "C")]
ph3 = PokerHand.new(arr3)
ph3.classify
assert_equal FOUR_OF_A_KIND, ph3.hand_type
end
new file Pokerhand.rb:
require "./Constants"
require "./Card"
require "./Deck"
require "./CardSpaceship"
class PokerHand < Deck
include Constants
attr_reader :hand_type
def initialize(the_cards)
#cards = [ ]
#hand_type = UNCLASSIFIED
for card in the_cards
#cards << card
end
end
# Determine hand type of PokerHand object.
def classify
#cards.sort!
# Straight flush
if #cards[0].rank == #cards[1].rank +1 &&
#cards[1].rank == #cards[2].rank +1 &&
#cards[2].rank == #cards[3].rank +1 &&
#cards[3].rank == #cards[4].rank +1 &&
#cards[0].suit == #cards[1].suit &&
#cards[1].suit == #cards[2].suit &&
#cards[2].suit == #cards[3].suit &&
#cards[3].suit == #cards[4].suit
#hand_type = STRAIGHT_FLUSH
end
end
new file test2.rb:
require './PokerHand'
require "./Constants"
require 'minitest/autorun'
class TestClass < MiniTest::Test
include Constants
def test_1
arr1 = [Card.new(2, "S"), Card.new(3, "S"),
Card.new(4, "S"), Card.new(5, "S"),
Card.new(6, "S")]
ph1 = PokerHand.new(arr1)
ph1.classify
assert_equal STRAIGHT_FLUSH, ph1.hand_type
end
getting error:
TestClass#test_1:
PokerHand.rb:145: warning: else without rescue is useless

Answer 1

The warning: else without rescue is useless warning is displayed when you setup an if/else statement improperly.
if true
puts 'hi''
end # end shouldn't be here
else
puts 'whoops'
end
You should find that in your code and correct it as well, although that isn't what is causing the fatal error.
The +1s in your if statement either need spaces or parentheses:
if #cards[0].rank == #cards[1].rank + 1 &&
or
if #cards[0].rank == (#cards[1].rank +1) &&
