Ruby | Hash merge function

Last Updated : 07 Jan, 2020

Hash#merge() is a Hash class method which combines two hash arrays and their content.

Syntax: Hash.merge() Parameter: Hash values Return: combine two hash arrays

Example #1 :

Ruby

# Ruby code for Hash.merge() 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}


# merge Value
puts "Hash a merge form : #{a.merge(b)}\n\n"

puts "Hash b merge form : #{b.merge(c)}\n\n"

puts "Hash c merge form : #{c.merge(a)}\n\n"

Output :

Hash a merge form : {:a=>100, :b=>200, :c=>300}

Hash b merge form : {:a=>100, :c=>300, :b=>200}

Hash c merge form : {:a=>100, :b=>200}

Example #2 :

Ruby

# Ruby code for Hash.merge() 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}

# merge Value
puts "Hash a merge form : #{a.merge(b)}\n\n"

puts "Hash b merge form : #{b.merge(c)}\n\n"

puts "Hash c merge form : #{c.merge(a)}\n\n"

Output :

Hash a merge form : {"a"=>100, "b"=>200}

Hash b merge form : {"a"=>100, "c"=>300, "b"=>200}

Hash c merge form : {"a"=>100, "c"=>300, "b"=>200}
