    public Person(String name, int age, String sex) {
        this.name = name;
        this.age = age;
        this.sex = sex;
    }
    public void setName(String name) {this.name = name;}
    public String getName() {return this.name;}
    public void setAge(int age) {this.age = age;}
    public String getAge() {return this.age;}
    public void setSex(String sex) {this.sex = sex;}
    public String getSex() {return this.sex;}
}
public class Student extends Person{
    private String school;
    public Student(String school, String name, int age, String sex) {
        super(name, age, sex);
        this.school = school;
    }
    public void setSchool(String school) {this.school = school;}
    public String getSchool() {return this.school;}
    public void static main(String[] args) {
        Person s1 = new Student("清华大学", "刘备", 18, "男");
