如何在java中读入多个项目时忽略逗号后的空格

import java.util.regex.Pattern;

public class Main {
    public static void main(String[] args) {
        String input = "project1, project2 , project3, project4 , project5";
        String pattern = ",\\s+";
        String result = input.replaceAll(pattern, ",");
        System.out.println(result);
    }
}

public class Main {
    public static void main(String[] args) {
        String input = "project1, project2 , project3, project4 , project5";
        String[] projects = input.split(",");
        for (int i = 0; i < projects.length; i++) {
            projects[i] = projects[i].trim();
        }
        for (String project : projects) {
            System.out.println(project);
        }
    }
}
