检查 ArrayList 的值 - IN A ROW - 是否相同

Question

我有一个问题似乎还没有找到答案。所以我有一个 ArrayList 包含两种类型的值：Won 或 Loss。这些值的顺序不同。我需要检查相同的值有多少次来自数组的顶部，以便显示例如一个用户连续赢了 5 次。

ArrayList <String> wins = new ArrayList<String>();
System.out.print(wins);

[Won, Won, Won, Loss, Loss, Won, Won, Loss, Loss, Loss, Loss, Loss, Won, Won, Won, Won, Won, Loss]

谁能解决这个问题？我已经尝试了一段时间，但不幸的是我还没有找到解决方案。 T

Answer 1

//假设List最少有一个元素

List<String> wins = Arrays.asList(new String[]{"Won", "Won", "Won", "Loss", "Loss", "Won", "Won", "Loss", "Loss", "Loss", "Loss", "Loss", "Won", "Won", "Won", "Won", "Won", "Loss"});
        System.out.println(wins);
        String value = wins.get(0);
        int maxValue=1;
        int count = 1 ;
        for(int i=1;i<wins.size();i++){
            if(wins.get(i) == wins.get(i-1)){
                count++;
                if(count >= maxValue){
                    maxValue = count;
                    value = wins.get(i);
                }
            }else{
                count=1;
            }
        }
        System.out.println(value + " : " + maxValue );
