  • Last Updated : 07 Jan, 2020

Hash#<() is a Hash class method which compares two Hash values.

Syntax: Hash.<()

Parameter: Hash values

Return: true – if a < b otherwise return false

Example #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"
  
puts "Hash b < c : #{b<c}\n\n"
  
puts "Hash a < c : #{c<a}\n\n"

Output :

Hash a < b : true

Hash b < c : false

Hash a < c : true

Example #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"
  
puts "Hash b < c : #{b<c}\n\n"
  
puts "Hash a < c : #{c<a}\n\n"
