洗牌一串字符串

核实

List<String> arr = Arrays.asList(imageThumbUrlsRandom);
Collections.shuffle(arr);
arr.toArray(imageThumbUrlsRandom);

如果您有自己的RNG(或者如果您只想为默认的RNG指定种子),您可以传递它:

long seed = 0xDEADBEEFL;
Random rng = new Random(seed);
List<String> arr = Arrays.asList(imageThumbUrlsRandom);
Collections.shuffle(arr, rng);
arr.toArray(imageThumbUrlsRandom);
