按属性将对象列表分组：Java

如何解决按属性将对象列表分组：Java

In Java 8:

Map<String, List<Student>> studlistGrouped =
    studlist.stream().collect(Collectors.groupingBy(w -> w.stud_location));

解决方法

我需要使用特定对象的属性（位置）对对象（学生）列表进行分组，代码如下所示，

public class Grouping {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {

        List<Student> studlist = new ArrayList<Student>();
        studlist.add(new Student("1726","John","New York"));
        studlist.add(new Student("4321","Max","California"));
        studlist.add(new Student("2234","Andrew","Los Angeles"));
        studlist.add(new Student("5223","Michael","New York"));
        studlist.add(new Student("7765","Sam","California"));
        studlist.add(new Student("3442","Mark","New York"));

        //Code to group students by location
        /*  Output should be Like below
            ID : 1726   Name : John Location : New York
            ID : 5223   Name : Michael  Location : New York
            ID : 4321   Name : Max  Location : California
            ID : 7765   Name : Sam  Location : California    

         */

        for (Student student : studlist) {
            System.out.println("ID : "+student.stud_id+"\t"+"Name : "+student.stud_name+"\t"+"Location : "+student.stud_location);
        }


    }
}

class Student {

    String stud_id;
    String stud_name;
    String stud_location;

    Student(String sid,String sname,String slocation) {

        this.stud_id = sid;
        this.stud_name = sname;
        this.stud_location = slocation;

    }
}

请给我建议一个干净的方法。
