Ruby Hash >=() 函数

Hash#>=()是一个Hash类方法，用于比较两个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
