Android studio 如何将数组添加到模型类中？

我只是想知道如何在模型类中添加一个数组，并在mainactivity中设置它？我已将部分模型类粘贴到下面：

  public class information {
private String[] Ranking;


 public Information() {
    }

public Information(String[] Ranking) {
Ranking = Ranking;
}

public String[] getRanking() {
        return Ranking;
    }

    public void setRanking(String[] ranking) {
        Ranking = ranking;
    }


In my mainactivity, should I do this?

private String[] Ranking;

Ranking[0] = "Gumshoe";




}
