Syntax: Hash.include?()
Parameter: Hash values

Example #1 :
# Ruby code for Hash.has_value?() 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 } # has_value? Value puts "Hash a has_value? form : #{a.include?(" a ")}\n\n" puts "Hash b has_value? form : #{b.has_value?(" c ")}\n\n" puts "Hash c has_value? form : #{c.has_value?(" c ")}\n\n" |
Output :
Hash a has_value? form : false Hash b has_value? form : false Hash c has_value? form : false
Example #2 :
# Ruby code for Hash.has_value?() 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 } # has_value? Value puts "Hash a has_value? form : #{a.include?(" a ")}\n\n" puts "Hash b has_value? form : #{b.has_value?(" c ")}\n\n" puts "Hash c has_value? form : #{c.has_value?(" c ")}\n\n" |
Output :
Hash a has_value? form : true Hash b has_value? form : false Hash c has_value? form : false
