Example #1 :






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

Output :

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

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

Hash c to_h form : {:a=>100}

Example #2 :




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

Output :

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

Hash b to_h form : {"a"=>100}

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