Groovyって継承もできるんだよな？と思って書いてみたサンプル

Groovyでの継承の例。
ウィザードリーのキャラクタをイメージして書いてみた。
ジョブチェンジすると５歳ふえるぞ！
コンストラクタの書き方が良くわからない。

// 全種族に共通のプロパティ

public class Specie {

    int age     // ねんれい

    int power   // ちから

    int speed   // すばやさ

    int vital   // たいりょく

    int piety   // しんこうしん

    int wisdom  // ちえ

    String sex  // せいべつ

    String job  // ジョブ

    

    toString() {

	strRet = "job is " + this.job + "\n" +

	"sex is " + this.sex + "\n" +

	"age is " + this.age.toString() + "\n" +

	"power is " + this.power.toString() + "\n" +

	"vital is " + this.vital.toString() + "\n" +

	"piety is " + this.piety.toString() + "\n" +

	"wisdom is " + this.wisdom.toString() + "\n"

	return strRet

    }

}

// 人間という種族を定義

public class Human extends Specie {

    // 初期値：コンストラクタにしたい！

    setHuman(strSex,strJob){

	this.age = 10

	this.power = 8

	this.speed = 8

	this.vital = 7

	this.piety = 8

	this.wisdom = 9

	this.sex = strSex

	this.job = strJob

    }
    jobChange(strJob){

	this.job = strJob

	this.age+= 5

    }

}

// エルフという種族を定義

public class Elf extends Specie {

    setElf(strSex,strJob){

	this.age = 9

	this.power = 6

	this.speed = 6

	this.vital = 8

	this.piety = 11

	this.wisdom = 12

	this.sex = strSex

	this.job = strJob

    }
    jobChange(strJob){

	this.job = strJob

	this.age+= 5

    }

}
taro = new Human()

taro.setHuman('male','Warrior')

println "taro is this\n" + taro.toString()

// たろうはジョブチェンジをした。

taro.jobChange('Lord')

println "taro is this\n" + taro.toString()
keiko = new Elf()

keiko.setElf('female','Mage')

println "keiko is this\n" + keiko.toString()

そして実行結果はこんな感じになる

age is 10

power is 8

vital is 7

piety is 8

wisdom is 9
taro is this
