如何使用Xstream将arraylist转换为xml文件

Okay so here's my constructor

好的，这是我的构造函数

public class Highscore implements java.io.Serializable{

    public String name;
    public double score;
    protected Highscore (String na, double sc){
        name = na;
        score = sc;
    }
    public String getName(){
        return name;
    }
    public double getScore(){
        return score;
    }
    public String toString(){
        return name + "has "+score+" points.";

    }
}
