Java |如何从字符串中删除常见词，然后连接不常用词？

import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;

public class StringManipulation {
    public static void main(String[] args) {
        String inputString = "This is a sample string with common words like is, a, and with.";
        String[] commonWords = {"is", "a", "and", "with"};

        // 将常见词转换为Set，以便快速查找
        Set<String> commonWordsSet = new HashSet<>(Arrays.asList(commonWords));

        // 将字符串拆分为单词数组
        String[] words = inputString.split("\\s+");

        // 构建新的字符串，连接不常用词
        StringBuilder result = new StringBuilder();
        for (String word : words) {
            if (!commonWordsSet.contains(word)) {
                result.append(word).append(" ");
            }
        }

        // 删除末尾的空格并打印结果
        String outputString = result.toString().trim();
        System.out.println(outputString);
    }
}
