Ruby Hash >()方法

Hash#>()是一个Hash类的方法，可以比较两个Hash值。

语法。Hash.>()

参数：哈希值

返回：真 – 如果a>b，否则返回假

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 : true

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 : true

Hash b > c : false

Hash a > c : true
