[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。
实验要求：
1. 画出对应的类图；
2. 提交源代码
TEST.JAVA
package makepeople;
import java.util.Scanner;
public class test {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner scan = new Scanner(System.in);
System.out.print("请输入参数:");
String s = scan.nextLine();
try{
Person p = Nvma.Personjudge(s);
p.make();
}catch(Exception e){
System.out.println(e.getMessage());
}
scan.close();
}
}
PERSON.JAVA
package makepeople;
public interface Person {
public void make();
}
Man.java
package makepeople;
public class Man implements Person{

public void make(){
System.out.print("生产男人");
}
}
Woman.java
package makepeople;

}
}
Robot.java

}
Nvma.java

}
public static Person Personjudge(String arg ) {
//判断参数，再选择调用哪个类
if(arg.equalsIgnoreCase("M"))
{

}else if(arg.equalsIgnoreCase("W"))
{
return new Woman();
}else if(arg.equalsIgnoreCase("R"))
{
return new Robot();
