红宝石 |哈希 eql?函数

Hash#eql?()是一个 Hash 类方法，用于检查两个 Hash 数组是否相等。

Syntax: Hash.eql?()

Parameter: Hash values

Return: true – if two hash arrays are equal otherwise return false

示例 #1：

# Ruby code for Hash.eql?() method
   
# declaring Hash value
a = {a:100, b:200}
   
# declaring Hash value
b = {a:100, c:300, b:200}
   
# declaring Hash value
c = {a:100}
   
   
# equal? Value
puts "Hash a equal? form : #{a.eql?(b)}\n\n"
   
puts "Hash b equal? form : #{b.eql?(c)}\n\n"
   
puts "Hash c equal? form : #{c.eql?(a)}\n\n"

输出 ：

Hash a equal? form : false

Hash b equal? form : false

Hash c equal? form : false

示例 #2：

# Ruby code for Hash.equal?() method
   
# declaring Hash value
a = { "a" => 100, "b" => 200 }
   
# declaring Hash value
b = {"a" => 100}
   
# declaring Hash value
c = {"a" => 100, "c" => 300, "b" => 200}
   
   
# equal? Value
puts "Hash a equal? form : #{a.eql?(b)}\n\n"
   
puts "Hash b equal? form : #{b.eql?(c)}\n\n"
   
puts "Hash c equal? form : #{c.eql?(a)}\n\n"

输出 ：

Hash a equal? form : false

Hash b equal? form : false

Hash c equal? form : false
