Assuming you mean "a variable that holds the class's name", check out 
Module.const_get. This method takes a string and returns the value of 
the constant having that name. Since the value of the constant Array is 
the Array class object, we can get the Array class object like this:

cls = Module.const_get("Array")

And then call new on the class object to create a new array:

ary = cls.new
