Ruby Hash == 函数

Hash#==() : ==()是一个Hash类方法，用于检查两个Hash值的相等性。

语法。Hash.==()

参数：哈希值

返回：true – 如果a == b 否则返回false

例子 #1:

# Ruby code for Hash.==() 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}
  
# COMPARING TWO Hash VALUES
puts "Hash a == b : #{a==b}\n\n"
  
# b
puts "Hash b == c : #{b==c}\n\n"
  
# c
puts "Hash a == c : #{c==a}\n\n"

输出:

Hash a == b : false

Hash b == c : false

Hash a == c : false

例子#2。

# Ruby code for Hash.==() 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}
  
  
# COMPARING TWO Hash VALUES
puts "Hash a == b : #{a==b}\n\n"
  
# b
puts "Hash b == c : #{b==c}\n\n"
  
# c
puts "Hash a == c : #{c==a}\n\n"

输出:

Hash a == b : false

Hash b == c : false

Hash a == c : false
