The following figure shows a UML diagram in which the class Student is inherited from the class Person. Implement the two classes. Write a demo program that tests all the methods in the Student class as well as the inherited methods. Note: In the toString method in the Student class, use the method getName() to get the name.

Exercise 3: The following figure shows a UML diagram in which the class student is inherited from the class Person Person name: String Person setName (String newName) void getName String toString String has SameName (Person another Person) boolean Student student Number: int Student reset (String newName int newNumber) void get StudentNumber int setstudent Number (int n) void tostring String equals (Student another Stuent) boolean

Solution

StudentDemo.java

public class StudentDemo {

  
   public static void main(String[] args) {
       Student s = new Student();
       s.reset(\"Suresh\",100);
       System.out.println(s);
       Student s1 = new Student();
       s1.reset(\"Ssekhar\",101);
       System.out.println(s1);
       Student s2 = new Student();
       s2.reset(\"Suresh\",100);
       System.out.println(s2);
       System.out.println(\"Object s and s1 equal: \"+s.equals(s1));
       System.out.println(\"Object s and s2 equal: \"+s.equals(s2));
      
      
   }

}

Student.java

public class Student extends Person{
   private int studentNumber;
   public Student(){
      
   }
   public int getStudentNumber() {
       return studentNumber;
   }
   public void setStudentNumber(int studentNumber) {
       this.studentNumber = studentNumber;
   }
   public void reset(String newName, int newNumber){
       super.setName(newName);
       this.studentNumber = newNumber;
   }
   public String toString(){
       return super.toString()+\" Number: \"+getStudentNumber();
   }
   public boolean equals(Student s){
       if(hasSameName(this) && getStudentNumber() == s.getStudentNumber()){
           return true;
       }
       return false;
   }
}

Person.java

public class Person {
   private String name;
   public Person(){
      
   }
   public String getName() {
       return name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public String toString(){
       return \"Name: \"+getName();
   }
   public boolean hasSameName(Person p){
       if(getName().equalsIgnoreCase(p.name)){
           return true;
       }
       return false;
   }
}

Output:

Name: Suresh Number: 100
Name: Ssekhar Number: 101
Name: Suresh Number: 100
Object s and s1 equal: false
Object s and s2 equal: true
