java - 如何检查任何数组列表是否包含特定字符串

Question

我正在尝试使用以下代码:

public void verifyCategorySlugsInSearchcall(BaseDTO baseDTO, String jsonResponse) {
        List<String> categoryList = JsonPath.read(jsonResponse,
                "response.groups.DEFAULT_GROUP.documents[*].categorySlugs[*]");
        CustomReporter.reportInfoWithOutLineBreak("Category from search call Response:" + categoryList);

        Assert.assertTrue(categoryList.size() > 0, "No category slug name was displayed.");

        CustomReporter.reportInfoWithOutLineBreak("Category Slug from  search call Response:" + categoryList);
        Assert.assertTrue(categoryList.contains(baseDTO.getPsCallDetails().getCategory()),
                "Category Name was not matching. Actual:" + categoryList + ".Expected:"
                        + baseDTO.getPsCallDetails().getCategory());
    }

我的数组列表包含所有类别名称:

例如:[“apple-tv-apple-tv-4k”，“apple-tv-apple-tv-4k”，“apple-tv-apple-tv”]

需要搜索此数组中包含的 apple-tv。我的代码给出错误，因为不包含特定类别的 apple-tv。

使用流:

boolean result = categoryList.stream()
    .anyMatch(c -> c.contains("apple-tv"));

如果您想生成一个仅包含名称中包含 apple-tv 的类别的新列表，请使用 filter:

List<String> output = categoryList.stream()
    .filter(c -> c.contains("apple-tv"))
    .collect(Collectors.toList());
