What does a Java static method look like in Ruby?

Question

In Java, a \'static method\' would look like this:

class MyUtils {
    . . .
    public static double mean(int[] p) {
        int sum = 0;  // sum of all the         


        

Answer 1

Anders' answer is correct, however for utility methods like mean you don't need to use a class, you can put the method in a module:

module MyUtils
  def self.mean(values)
    # implementation goes here
  end
end

The method would be called in the same way:

avg = MyUtils.mean([1,2,3,4,5])

Answer 2

Use self:

class Horse
  def self.say
    puts "I said moo."
  end
end

Horse.say
