我连这是一题还是四题都不知道，有没有人告诉我怎么做啊，

四、编程题定义一个表示学生信息的类 Student，要求如下：
1.类的成员变量有：
sNo 表示学号
sName
表示姓名
sSex
表示性别
sAge
表示年龄
sJava 表示 Java 课程的成绩
2.类的带参数的构造方法。
3.类的成员方法：
getNo()
获得学号
getName()
获得姓名
getSex()
获得性别
getAge()
获得年龄
getlava()
获得 Java 课程的成绩
4.根据类 Student 的定义，创建一个该类的对象，对象名自定义，并给其属性自定义赋值，然后输出学号,
姓名，性别，年龄，Java 课程的成绩信息。

这是一个题，代码如下。有用请采纳

public class Student {
    private String sNo;//学号
    private String sName;//姓名
    private String sSex;//性别
    private Integer sAge;//年龄
    private Integer sJava;//Java 课程的成绩

    public String getsNo() {
        return sNo;
    }

    public void setsNo(String sNo) {
        this.sNo = sNo;
    }

    public String getsName() {
        return sName;
    }

    public void setsName(String sName) {
        this.sName = sName;
    }

    public String getsSex() {
        return sSex;
    }

    public void setsSex(String sSex) {
        this.sSex = sSex;
    }

    public Integer getsAge() {
        return sAge;
    }

    public void setsAge(Integer sAge) {
        this.sAge = sAge;
    }

    public Integer getsJava() {
        return sJava;
    }

    public void setsJava(Integer sJava) {
        this.sJava = sJava;
    }

    public Student(String sNo, String sName, String sSex, Integer sAge, Integer sJava) {
        this.sNo = sNo;
        this.sName = sName;
        this.sSex = sSex;
        this.sAge = sAge;
        this.sJava = sJava;
    }
    
    public Student() {
        this.sNo = sNo;
        this.sName = sName;
        this.sSex = sSex;
        this.sAge = sAge;
        this.sJava = sJava;
    }
    
    @Override
    public String toString() {
        return "Student{" +
                "sNo='" + sNo + '\'' +
                ", sName='" + sName + '\'' +

    }
    
    public static void main(String[] args) {
        Student student = new Student();
        student.setsNo("001");
        student.setsName("张三");
        student.setsSex("男");
        student.setsAge(20);
        student.setsJava(100);
        System.out.println(student);
    }
}

class Student{

    private String sNo;

    private String sName;

    private String sSex;

    private Integer sAge;

    private Integer sJava;

    }

    public String getsNo() {
        return sNo;
    }

    public String getsName() {
        return sName;
    }

    public String getsSex() {
        return sSex;
    }

    public Integer getsAge() {
        return sAge;

        return sJava;
    }

    public static void main(String[] args) {
        Student student = new Student("1101", "张三", "男", 18, 98);
        System.out.println(student.getsAge());
        System.out.println(student.getsJava());
        System.out.println(student.getsName());
        System.out.println(student.getsSex());
