如 果 想 進 行 Java 函 式 庫 的 實 驗 測 試， 最 好 能 在 Mathematica 內 實 作 函 式 庫 介
面， 這 只 需 使 用
ImplementJavaInterface
指 令 便 可 輕 鬆 達 成。 以 下 範 例 使
用
ImplementJavaInterface
指 令 修 改 背 包 問 題 的 演 化 適 應 函 數； 需 注 意 的 是，
ImplementJavaInterface
指令只 能用在 具體介面 而無法 用於抽 象類別。在 JGAP 中，
FitnessFunction
函式是一個抽象類別，因此我們無法使用
ImplementJavaInterface
指
令進行實作，於此情況下，我們可以用下列方式建立接合程式碼（adapter）。
藉由以上的演化適應函數，讓我們可於 Mathematica 中使用下列介面。

完成上列程式後，我們便能使用 Mathematica 中建立的函數作為演化適應函數，這個方
法是通用的，你可以用這個方法接合 Java 函式庫中的任意抽象類別。以下我們利
