Ruby | Hash < method

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"

Output :

Hash a < b : false

Hash b < c : true

Hash a < c : false
