Java 数组最大值下标查找方法

public List findMaxIndices(int[] arr) { List maxIndices = new ArrayList<>(); int max = Integer.MIN_VALUE;

for (int i = 0; i < arr.length; i++) {
    if (arr[i] > max) {
        max = arr[i];
        maxIndices.clear();
        maxIndices.add(i);
    } else if (arr[i] == max) {
        maxIndices.add(i);
    }
}

return maxIndices;

}
