JSON字符串转javaModel对象错误? 报错

"

import java.util.List;

public class PersonTest {

private String name;
private Game game;

public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public Game getGame() {
    return game;
}
public void setGame(Game game) {
    this.game = game;
}

}

public class Game {
    private String[] string;

    public String[] getString() {
        return string;
    }

    public void setString(String[] string) {
        this.string = string;
    }
}

public class MTest {
    public static void main(String[] arg) throws IOException{
        String json = "[{\"name\":\"Jack\",\"game\":{\"string\":[\"2\",\"3\"]}},{\"name\":\"Jack\",\"game\":{\"string\":[\"2\",\"3\"]}}]";
        JSONArray jsonobject = JSONArray.fromObject(json);
        List<PersonTest> list1 = (List<PersonTest>)JSONArray.toArray(jsonobject,PersonTest.class);
        for(PersonTest u : list1){
            System.out.println(u.getName());
        }
    }
}

为什么转换不了...报错了,哪里写的有错吗?
