希望对你有帮助吧！

程序代码：

package myStudent;

public class Student {

    private String name;
    private double mark;

    public Student()
    {
    }

    public Student(String name, double mark) {
        super();
        this.name = name;
        this.mark = mark;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getMark() {
        return mark;
    }

    public void setMark(double mark) {
        this.mark = mark;
    }
}

程序代码：

package myStudent;

public class StudentTest {

    public static void main(String[] args) {
        Student s1 = new Student();
        s1.setName("李四");
        s1.setMark(99.0);
        String name1 = s1.getName();
        double mark1 = s1.getMark();

        Student s2 = new Student("张三",98.0);
        String name2 = s2.getName();
        double mark2 = s2.getMark();

        System.out.println("姓名:"+name1+"   成绩:"+mark1);
        System.out.println("姓名:"+name2+"   成绩:"+mark2);
    }
}

程序代码：

Student.java文件代码
//1、Student类中包含姓名、成绩两个属性。
//2、分别给这两个属性定义两个方法，一个方法用于设置值，另一个方法用于获取值。
//3、Student类中定义一个无参的构造方法和一个接受两个参数的构造方法，两个参数分别为姓名和成绩属性赋值。
public class Student {
    private String name;
    private int score;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getScore() {
        return score;
    }
    public void setScore(int score) {
        this.score = score;
    }
    public Student(String name, int score) {
        this.name = name;
        this.score = score;
    }
    public Student() {
        this.name="sys";
        this.score=12;
    }
    @Override
    public String toString() {
        return "Student [name=" + name + ", score=" + score + "]";
    }

}
StudentTest.java文件代码
import java.import java.util.Iterator;
import java.util.Random;
import java.util.TreeSet;

//4、在测试类中创建两个Student对象，
//一个使用无参的构造方法，然后调用方法给姓名和成绩赋值，
//另一个使用有参的构造方法，在构造方法中给姓名和成绩赋值。
//5、给个完整的的代码，带输出的那种
public class StudentTest {
    public static void main(String[] args) {
        TreeSet<Student> ts=
                new TreeSet<Student>(new Comparator<Student>(){
                    @Override
                    public int compare(Student o1, Student o2) {
//                        return o1.getScore()-o2.getScore();
                        return o1.getName().compareTo(o2.getName());
                    }
                });
        Random r=new Random();
        ts.add(new Student());
        for(int i=0;i<9;i++)
            ts.add(new Student("a"+r.nextInt(10),r.nextInt(100)));
        Iterator<Student> itr=ts.iterator();
        while(itr.hasNext()){
            System.out.println(itr.next());
        }
    }

}
