java - 检查 ArrayList 的值(在一行中)是否相同

Question

我有一个问题，但似乎没有找到答案。所以我有一个由 2 种类型的值组成的 ArrayList:赢或输。这些值的顺序不同。我需要检查相同的值来自数组顶部的次数，以便显示例如用户连续获胜 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]

有人能解决这个问题吗？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。

Answer 1

//假设List至少有一个元素

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 );
