Ruby Hash 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。

语法。Hash.eql?()

参数：哈希值

返回：true – 如果两个哈希数组相等，否则返回false

例子 #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

例子 #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
