字符串与Java Map中的键进行比较

Question

我有一个Map（String，String）和String inputText的集合。 如果其中包含Map中的任何键，您可以建议如何扫描inputText以进行检查。

例如，我有下一个：

    //hashmap is used - I don't need the order
    Map<String, String> mapOfStrings = new HashMap<String,String>();
    mapOfStrings.put("java","yep, java is very useful!");
    mapOfStrings.put("night","night coding is the routine");

    String inputText =  "what do you think about java?"
    String outputText = ""; //here should be an <answer>
    Set<String> keys = mapOfStrings.keySet();
    for (String key:keys){
        String value = mapOfStrings.get(key);
        //here it must uderstand, that the inputText contains "java" that equals to
        //the key="java" and put in outputText the correspondent value
    }

我所知道的不是equals（）或compareTo（）。 可能是我应该以某种方式检查inptuText中字符的顺序吗？

问候

Answer 1

您可以使用以下内容：

for (String key:keys){
        String value = mapOfStrings.get(key);
        //here it must uderstand, that the inputText contains "java" that equals to
        //the key="java" and put in outputText the correspondent value
        if (inputText.contains(key))
        {
           outputText = value;
        }
    }
