Use dot notation to chain respond_to?
onto the string
variable (lowercase s). Then pass in the method (upcase
) either as a symbol, :upcase
or as a string, "upcase"
:
#symbol uses a preceding colon
string.respond_to? :upcase
# or
string.respond_to?("upcase") # parentheses optional
I hope that helps,
Steve.
