Last Updated : 07 Jan, 2020

Hash#replace() : replace() is a Hash class method which replaces the content of one hash with other.

Syntax: Hash.replace()

Parameter: Hash values

Return: replaces the content of one hash with other.

Example #1 :

# Ruby code for Hash.replace() 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} 
  
  
# replace Value 
puts "Hash a replace form : #{a.replace(b)}\n\n"
  
puts "Hash b replace form : #{b.replace(c)}\n\n"
  
puts "Hash c replace form : #{c.replace(a)}\n\n"

Output :

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

Hash b replace form : {:a=>100}

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

Example #2 :

# Ruby code for Hash.replace() 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} 
  
  
# replace Value 
puts "Hash a replace form : #{a.replace(b)}\n\n"
  
puts "Hash b replace form : #{b.replace(c)}\n\n"
  
puts "Hash c replace form : #{c.replace(a)}\n\n"

Output :

Hash a replace form : {"a"=>100}

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

Hash c replace form : {"a"=>100}
