Answer to Question #317706 in Java | JSP | JSF for oslo

Question

a) Create a java project named school

b) Add two classes, namely student and lect

c) In student class, create the following methods:

i. calculate_stud_age – This method should take year of birth of the student as a

parameter and calculate and return the student’s age

ii. calculate_ave_mark – This method should take three marks of the student ,

Math, English and Physics marks as parameters and return the average mark.

d) In the lect class, create the following methods:

i. get_name – This method should take a string (name of the lect) and

an integer (experience of the lect in years). This method should

output the name of the Lect together with his designation

based on the years of experiences determined by the following:

Professor – if experience is >= 20 years

Associate professor – if experience is >=15 years

Senior lecturer – if experience is >= 10 years

Associate lecturer – if experience is >=5 years

Junior lecturer – if experience is <5 years

Answer 1

import java.util.Scanner;

class Student{

    public int calculate_stud_age(int birth){
        return 2022 - birth;
    }

    public double calculate_ave_mark(double math, double engl, double phys){
        return (math+engl+phys)/3;
    }
}

class Lect{
    public void get_name(String name, int experience){
        if(experience < 5){
            System.out.println("Lecturer's name: " + name + "\nBy his appointment Junior lecturer");
        } else if(experience >=5 & experience < 10){
            System.out.println("Lecturer's name: " + name + "\nBy his appointment Associate lecturer");
        } else if(experience >=10 & experience < 15){
            System.out.println("Lecturer's name: " + name + "\nBy his appointment Senior lecturer");
        } else if(experience >=15 & experience < 20){
            System.out.println("Lecturer's name: " + name + "\nBy his appointment Associate professor");
        } else if(experience >= 20){
            System.out.println("Lecturer's name: " + name + "\nBy his appointment Professor");
        }
    }

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);

        Student student = new Student();
        Lect lect = new Lect();

        System.out.print("Enter student's year of birth: ");
        int yearsOld = student.calculate_stud_age(in.nextInt());
        System.out.print("Enter his math grade: ");
        int math = in.nextInt();

        int engl = in.nextInt();
        System.out.print("Enter his grade in physics: ");
        int phys = in.nextInt();
        System.out.println("Student age: " + yearsOld + "\nAverage score in subjects: " + student.calculate_ave_mark(math, engl, phys));

        System.out.print("Enter lecturer's name: ");
        String name = in.next();

        System.out.print("Enter lecture experience in years: ");
        lect.get_name(name, in.nextInt());

    }
