java - 如何检查列表是否包含 Java 中给定顺序的子列表

Question

我在 groovy 中阅读 how to check if a list contains a sublist - stackoverflow .

如果有一种方法可以检查列表是否包含子列表，但以给定的顺序，我很感兴趣。例如，此代码将给出 true,

    List<String> list = Arrays.asList("PRP", "VBP", "VBN", "NN", "NNS", "MD", "VB");
    List<String> sublist = Arrays.asList("MD", "VB", "VBN");
    System.out.println(list.containsAll(sublist));

但我想找回false。

您可以使用方法Collections.indexOfSubList .

Returns the starting position of the first occurrence of the specified target list within the specified source list, or -1 if there is no such occurrence. More formally, returns the lowest index i such that source.subList(i, i+target.size()).equals(target), or -1 if there is no such index. (Returns -1 if target.size() > source.size().)

int index=Collections.indexOfSubList(list , sublist);

简短内容:
如果 Collections.indexOfSubList(list , sublist) =! -1 你会有一场比赛
