using System;

class Dog

    private int weight;
    private string name;
    public Dog(int weight, string name)
    {
        this.weight = weight;
        this.name = name;
    }
    public int Weight
    {
        get { return weight; }
        set { weight = value; }
    }
    public string Name
    {
        get { return name; }

        Dog milo = new Dog(26, "Milo");
        Dog frisky = new Dog(10, "Frisky");
        Dog laika = new Dog(50, "Laika");
        Dog[] dogs = { milo, frisky, laika };
        foreach (Dog dog in dogs)
        {
            Console.WriteLine("Name:{0}, Weight:{1}", dog.Name, dog.Weight);
        }
    }
    static void Main()
    {
        Tester t = new Tester();
        t.Run();
    }
}

入出力結果(Console Window)

Name:Milo, Weight:26
Name:Frisky, Weight:10
Name:Laika, Weight:50

ちなみにJavaScriptの場合。

コード(BBEdit)

var Dog = function(weight, name){
  var weight = weight;
  var name = name;
  this.get_weight = function(){
    return weight;
  };
  this.set_weight = function(value){
    weight = value;
  };
  this.get_name = function(){
    return name;
  };
  this.set_name = function(value){
    name = value;
  };
};
var milo = new Dog(26, "Milo");
var frisky = new Dog(10, "Frisky");
var laika = new Dog(50, "Laika");
var dogs = [milo, frisky, laika];
var result = "";
for(var i = 0; i < dogs.length; i++){
  result += "Name:" + dogs[i].get_name() + ", " +
            "Weight:" + dogs[i].get_weight() + "\n";
}
$('#pre0').text(result);

pythonの場合。

sample.py

コード(BBEdit)

#!/usr/bin/env python3.3
# -*- coding: utf-8 -*-

class Dog:
    def __init__(self, weight, name):
        self._weight = weight
        self._name = name
    def get_weight(self):
        return self._weight
    def set_weight(self, value):
        self._weight = value
    def get_name(self):
        return self._name
    def set_name(self, value):
        self._name = value

milo = Dog(26, "Milo")
frisky = Dog(10, "Frisky")
laika = Dog(50, "Laika")
dogs = [milo, frisky, laika]
for dog in dogs:
    print("Name:{0} Weight:{1}".format(dog.get_name(), dog.get_weight()))

入出力結果(Terminal)
