Answer 1

Solution :

public $\text{class}$ Student {

$\text{protected String}$ school$;$

public $\text{Student}$(String school) {

$\text{this.school}$ = school;

}

public String $\text{toString}()$ {

return $\text{"student at"}$ + school;

}

}

HighSchool$\text{Student.java}$ :

public class $\text{HighSchoolStudent}$ extends Student {

public $\text{HighSchoolStudent}$(String school) {

super$\text{(school)}$;

}

public String $\text{toString}()$ {

return $\text{"high school"}$ + super.$\text{toString}()$;

}

}
