Java:检查字符串是否在字典中 [英] Java: Check if a string is in a dictionary
问题描述
我有一个语言字典(即英语,意大利语等),这本质上是每一行都有一个单词的文件。
I have a language dictionary (i.e. english,italian,etc...), that essentially is a file with one word on every line.
现在我想创建一个类,其方法是在输入中给出字符串检查该字符串是否存在于该字典中。
Now i want to create a class with a method that given a string in input check if that string exists into that dictionary.
我的想法是该方法返回一个布尔值。在伪代码中:
My idea is that the method return a boolean value. In pseudocode:
boolean checkWord(String s){
if(StringIsInDictionary) return true;
return false
}
应该是实现该功能的最佳方法?
What should be the best way to implement that feature?
考虑到该文件将包含约65000个单词。
Consider that the file will contain ~65000 words.
推荐答案
将字典读入 Set< String>
(例如, HashSet< String>
),然后使用 set.contains(word)
。
Read the dictionary into a Set<String>
(for example, HashSet<String>
), and then use set.contains(word)
.
