java - Java 中的字符串与 Map 中的键进行比较

Question

我有一个集合 Map 作为 (String,String) 和字符串 inputText。您建议扫描 inputText 来检查它是否包含 Map 中的任何键。

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
    }

据我所知，这不是 equals() 或compareTo()。也许我应该以某种方式检查 inptuText 中的字符顺序？

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;
        }
    }
