Perhaps you want:
Person = Class.new
or
Object.const_set "Person", Class.new
Both will create a new class named "Person". The second method will
let you use a name determined at runtime. If I understand your Java
code above, the Ruby translation would be something like this:
klass = Object.const_set("Person", Class.new)
person = klass.new
