如何在Ruby中比较和打印匹配的哈希值？

hash1 = { name: "John", age: 30 }
hash2 = { name: "John", age: 30 }
hash3 = { name: "Jane", age: 25 }

# 比较哈希值
if hash1 == hash2
  puts "hash1 and hash2 are equal"
else
  puts "hash1 and hash2 are not equal"
end

if hash1 == hash3
  puts "hash1 and hash3 are equal"
else
  puts "hash1 and hash3 are not equal"
end

hash1 and hash2 are equal
hash1 and hash3 are not equal
