Get method name as string or symbol in ruby

I have an array of methods like this:

def method1
  1
end

def method2
  2
end

m = [method1, method2]

I want to print the method names and values that are in m so that I get an output like:

method1: 1
method2: 2

Is it possible to get the name of a defined method as string or symbol? How can I get a method name as string or symbol?

After this the line m = [ method1, method2 ] the variable m has no information anymore about the methods that were called to assign [1, 2] to m.

Therefore, instead of storing the values that were returned by the methods I purpose to just store the method names in the array and use public_send to call the method when you need both their names and their return values:

m = [:method1, :method2]

def method1
  1
end

def method2
  2
end

m.each { |name| puts "#{name}: #{public_send(name)}" }
# => method1: 1
#    method2: 2

Or you might want to use a hash to store the method names and the returned values right away when assigning tehm to m:

m = { method1: method1, method2: method2 }
m.each { |name, value| puts "#{name}, #{value}" }
