class Person {
    private String name;
    private int age;

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

    public void setAge(int age) {
        this.age=age;
    }

    public String getName(){
        return name;
    }

    public int getAge(){
        return age;
    }
}

class Student extends Person {
    private String school;
    public String getSchool() {
        return school;
    }
    public void setSchool(String school) {
        this.school =school;
    }
}

public class Test {
    public static void main(String arg[]){
        Student student = new Student();
        student.setName("John");
        student.setAge(18);
        student.setSchool("SCH");
        System.out.println(student.getName());
        System.out.println(student.getAge());
        System.out.println(student.getSchool());
