# A simple Employee class 
class Employee 
    attr_reader :first_name, :last_name, :title, :age 

    def initialize(fname, lname, title, age) 
    @first_name = fname 
    @last_name = lname 
    @title = title 
    @age = age 
    end 
    # A string representation of the Employee object 
    def to_s 
    "#{first_name} #{last_name}, #{title}, #{age}" 
    end 
end 
# The collection class for Employee objects 
class Employees 
    include Enumerable 

    def initialize 
    @employees = [] 
    end 
    # Add Employee objects to the collection 
    def <<(employee) 
    @employees << employee 
    end 
    # Method mandated by the Enumerable module 
    def each 
    @employees.each { |e| yield(e) } 
    end 
end 
employees = Employees.new 

employees << Employee.new('Anita', 'Baker', 'President', 48) 
employees << Employee.new('Frank', 'Gifford', 'Director', 58) 
employees << Employee.new('Barbara', 'Eden', 'Secretary', 34) 
employees << Employee.new('George', 'Clooney', 'Project Manager', 37) 
employees << Employee.new('Emily', 'Davies', 'Programmer', 28) 
employees << Employee.new('David', 'Faber', 'Programmer', 55) 
employees << Employee.new('Cindy', 'Adams', 'Programmer', 33) 
employees << Employee.new('Helen', 'Hamilton', 'Business Analyst', 42)

您还想要我们做什么？ – NSNoob

是的，我想知道如何使搜索只显示特定的parts.Like当搜索名字输出只会显示年龄基本上如何添加条件thx。 – matuk1996

您已经通过实施Enumerable接口完成所有必要的工作名字搜索。只需接受用户输入并拨打Enumerable#find方法即可：

fname = gets.chomp 
e = employees.find {|i| i.first_name == fname}
