java - 错误: incompatible types return scores; required: int found: ArrayList

Question

//Class declaration of Player class
public class Player
{
/*--------------- Data Fields ---------------------------------------
Attributes of the class
*/
private String name;
private int playerId;
private int bestScore;
private static int numberOfPlayers = 0;
private ArrayList<Integer> scores = new ArrayList<Integer>();

//Create set method for setScores
public void setScore(int score)
{
    scores.add(score);
}

//Create get method for getScores
public int getScores()
{
    return scores;
}
}

我尝试寻找解决方案，但似乎找不到。我被要求为一名猜谜游戏的玩家存储 5 个分数。我只是想知道我应该在 getScore 方法中放入什么。

Answer 1

看这里，问题就在这里:

public int getScores()
{
    return scores;
}

您正在从声明返回 int 的方法返回 ArrayList
