Java 如何将两个列表与旧顺序合并？

我有两份清单：

    private static final List<String> NUMERIC_VALUES = Arrays.asList("100","5","1","0","1111111","6","11","12","50","99","101");

    private static final List<String> ALPHANUMERIC_VALUES = Arrays.asList("10A0", "1B1", "6A", "A0", "A1", "ABC", "C5", "T-1", "TT", "TTT",
                    "434/32145", "434/12354", "32654B", "32654A", "32654B/1");

我试过：

List<String> result = Stream.concat(NUMERIC_VALUES.stream(), ALPHANUMERIC_VALUES.stream()).collect(Collectors.toList());  

但这很有效：

//to concat two list
 List<String> result = Stream.concat(list1.stream(), list2.stream()).collect(Collectors.toList());

  result.forEach(s->System.out.print(s+" "));

//连接两个列表
列表结果=Stream.concat（list1.Stream（），list2.Stream（））.collect（Collectors.toList（））；
result.forEach（s->System.out.print（s+）；

您发布的代码似乎没有问题。可能还有其他问题。真的很抱歉！但是使用concat我会得到你想要的结果！您可以检查此链接<？>并获取代码并编译

List<String> result = new ArrayList<String>();
result.addAll(NUMERIC_VALUES);
result.addAll(ALPHANUMERIC_VALUES);

[100, 5, 1, 0, 1111111, 6, 11, 12, 50, 99, 101, 10A0, 1B1, 32654A, 32654B, 32654B/1, 434/12354, 434/32145, 6A, A0, A1, ABC, C5, T-1, TT, TTT]

//to concat two list
 List<String> result = Stream.concat(list1.stream(), list2.stream()).collect(Collectors.toList());

  result.forEach(s->System.out.print(s+" "));
