女娲造人

[实验任务一]：女娲造人

使用简单工厂模式模拟女娲(Nvwa)造人(Person)，如果传入参数M，则返回一个Man对象，如果传入参数W，则返回一个Woman对象，如果传入参数R，则返回一个Robot对象。请用程序设计实现上述场景。

package org.example;

public class Main {
    public static void main(String[] args) {
        Person man = NvwaFactory.createPerson("M");
        man.display();

        Person woman = NvwaFactory.createPerson("W");
        woman.display();

        Person robot = NvwaFactory.createPerson("R");
        robot.display();
    }
}

package org.example;

public class Man implements Person {
    @Override
    public void display() {
        System.out.println("这是男人");
    }
}

package org.example;

public class NvwaFactory {
    public static Person createPerson(String type) {
        if ("M".equals(type)) {
            return new Man();
        } else if ("W".equals(type)) {
            return new Woman();
        } else if ("R".equals(type)) {
            return new Robot();
        } else {
            throw new IllegalArgumentException("Unsupported type: " + type);
        }
    }
}

package org.example;

public interface Person {
    void display();
}

package org.example;

public class Robot implements Person {
    @Override
    public void display() {
        System.out.println("这是机器人");
    }
}

package org.example;

public class Woman implements Person {
    @Override
    public void display() {
        System.out.println("这是女人");
    }
