Java 類中包含其他類，多個類間相互調用，賦值操作的實現

存疑，尚未解決。待更

 

 

問題：

男人類： 

• 姓名、 年齡
• 妻子類
• 孩子類
• 方法 work()

女人類：

• 姓名、年齡
• 丈夫類
• 孩子類
• 方法 playSister()

孩子類：

• 姓名、年齡、性別
• 父親類
• 母親類
• 方法 study()

家庭類：

• 男人類
• 女人類
• 孩子類
• 方法 happy()

 

要求創建男人、女人、孩子、家庭對象，相互賦值，運行一下其中的方法。

Main 類，以及 main  方法

package qiantaodiaoyong;

public class Main {
	public static void main(String[] args) {

		child.setFather(man);
		child.setMother(woman);
		child.setAge(1);
		man.setChild(child);
		woman.setChild(child);
		//他們組成了美滿幸福的家庭
		Family family = new Family(man, woman, child);
		//偶爾happy一下
		family.happy();
		System.out.println(family.getMan().getName());
		System.out.println(family.getMan().getAge());
		System.out.println(family.getMan().getWife().getChild().getName());
	}
