java programing

Q: Given the following class:

public class Student {

private String firstName;

private String lastName;

private int age;

private University university;

public Student(String firstName, String lastName, int age, University university) {

this.firstName = fisrtName;

this.lastName = lastName;

this.age = age;

this.university = university;

}

public String getFirstName(){

return firstName;

}

public String getLastName(){

return lastName;

}

public int getAge(){

return age;

}

public University getUniversity(){

return university;

}

public String toString() {

return "\nFirst name:" + firstName + "\nLast name:" + lastName + " \nAge:"+ age + "\nUniversity" + university;

}

}

a- Create the University class (data type). The class must include name, state, and the country as member variables; it must also include methods for returning and storing the name, state, and country.

b- Create client code to test the classes.

Answer 1

Code:

import java.util.*;

class University{
    private String name;
    private String state;
    private String country;


    public University(String name, String state, String country) {
        this.name = name;
        this.state = state;
        this.country = country;
    }

    public String getName() {
        return this.name;
    }

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

    public String getState() {
        return this.state;
    }

    public void setState(String state) {
        this.state = state;
    }

    public String getCountry() {
        return this.country;
    }

    public void setCountry(String country) {
        this.country = country;
    }

    @Override
    public String toString() {
        return "{" +
            " name='" + getName() + "'" +
            ", state='" + getState() + "'" +
            ", country='" + getCountry() + "'" +
            "}";
    }

}

class Student {
    private String firstName;
    private String lastName;
    private int age;
    private University university;

    public Student(String firstName, String lastName, int age, University university) {
        this.firstName = firstName;
        this.lastName = lastName;
        this.age = age;
        this.university = university;
    }

    public String getFirstName() {
        return firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public int getAge() {
        return age;
    }

    public University getUniversity() {
        return university;
    }

    public String toString() {
        return "\nFirst name:" + firstName + "\nLast name:" + lastName + " \nAge:" + age + "\nUniversity" + university;
    }
}

class Main {

    public static void main(String args[]) {
        University u1 = new University("University of California", "California", "USA");
        Student s1 = new Student("Javed","Akhtar",22,u1);

        System.out.println(s1.toString());
    }
}

Code output:
