Thanx  robert

I have built a program but wants to make it more short . SO plz see 
wether is it possible or not

class  Employee
  attr_accessor :name ,:age, :address, :idno
end

   a = Array.new
   e1 = Employee.new
   e1.name = "Cindy"
   e1.age = 24
   e1.address = "Mumbai"
   e1.idno = 121
   a.push(e1) # insert the values of e1 in the array a
   puts '------------------------'
   e2 = Employee.new
   e2.name = "Kennedy"
   e2.age = 29
   e2.address = "Kolkata"
   e2.idno = 131
   a.push(e2)  # insert the values of e2 in the array a
   puts '------------------------'
   e3 = Employee.new
   e3.name = "Pearl"
   e3.age = 35
   e3.address = "Chennai"
   e3.idno = 141
   a.push(e3)  # insert the values of e3 in the array a

   a.sort!{|x,y|
   x.idno <=> y.idno

   }

   a.collect!{|x|puts "#{x.name}  #{x.age} #{x.address} #{x.idno}"}
