检查字符串包含在哈希表值中

Question

1=[Fletcher Christian, No, Visualisation of Egocentric Networks, Exploring the Irish Political Landscape on Twitter, Twitter Network Analysis, A Web-Based Server Energy Model Generator, Recommending Movies Using Curated IMDb Lists, Travel Planner for Commuters, Analysis of urban street networks - constructing a dual representation, Biography Reading Media Assistant]

我有 hash-table 喜欢 above.i 想要查找 Fletcher Christian 是否包含在 Hash-Table 值

中

这里的值是一个向量

Answer 1

只需遍历所有值并检查：

static boolean contains (Hashtable <Integer, Vector <String>> map, String value){
    for (Vector<String> values : map.values()){
        if (values.contains(value))
            return true;
    }
    return false;
}

在 Java 8 中，您可以用一行来完成：

static boolean contains (Hashtable <Integer, Vector<String>> map, String value){
    return map.values().stream().anyMatch(list -> list.contains(value));
}

检查字符串包含在哈希表值中

check String contains inside HashTable Value

java

hashtable
