Question

Naming Requirements:

These are the names you are required to use for your lab project. Make sure the letter casing is also the same (for example, Example.java is not the same as example.java).

• Java file name: Student.java

• Main class name: Student

MAKE SURE TO ONLY SUBMIT Student.java

Core Requirements:

• In this lab, we will be creating our own Student class. Implement the following specification below to create the class.

• Private Data Members:

  • String name

  • int points

• Public Static Data Members:

  • int studentCount

• Constructor:

  • public Student(String nameArg)

    • Set (name) to (nameArg)

    • Set (points) to 0

    • Increment (studentCount) by 1

• Public Methods:

  • public String getName()

    • Returns the data member (name)

  • public int getPoints()

    • Returns the data member (points)

  • public void setPoints(int pointsArg)

    • Set (points) to (pointsArg)

  • public int utorStudent(Student otherStudent)

    • Increment (otherStudent)’s (points) by 1 (Hint: use the setPoints method)

    • Returns (otherStudent)’s (points) after increment

• Now it’s time to test your Student class

• Copy the provided file Classroom.java into your project’s source folder

• Run the file and check your results

Answer 1

//CODE TO COPY

public class Student {

   private String name;
   private int points;

   public static int studentCount;

   public Student(String nameArg) {
       this.name = nameArg;
       this.points = 0;
       studentCount++;
   }

   public String getName() {
       return name;
   }

   public int getPoints() {
       return points;
   }

   public void setPoints(int pointsArg) {
       this.points = pointsArg;
   }

   public int utorStudent(Student otherStudent) {
       otherStudent.setPoints(points + 1);
       return otherStudent.points;
   }

}

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

THE ABOVE METHOD JUST INCREMENTS OTHER STUDENTS POINT BY ONE

IF YOU WANT TO DECREMENT CURRENT STUDENTS POINT BY 1 AND INCREMENT OTHER STUDENTS POINT BY 1, THEN REPLACE utorStudent() METHOD WITH THIS METHOD:

public int utorStudent(Student otherStudent) {
       this.setPoints(points-1);
       otherStudent.setPoints(points + 1);
       return otherStudent.points;
   }

EXPLANATION

public class Student {//creating a class Student.java

   //private members name,points
   private String name;
   private int points;

   //public static variable studentCount
   public static int studentCount;

   //Constructor with one argument nameArg
   public Student(String nameArg) {
       this.name = nameArg;//assign name as nameArg
       this.points = 0;//assigning points as 0
       studentCount++;//increment studentCont by 1
   }
  
   //Public Methods
   public String getName() {//method getName
       return name;//returning name
   }

   //method get Points
   public int getPoints() {
       return points;//returns points
   }

   //method setPoints
   public void setPoints(int pointsArg) {
       this.points = pointsArg;//set points as pointArgs
   }

   //method utorStudent which takes otherStudent as parameter
   public int utorStudent(Student otherStudent) {
       otherStudent.setPoints(points + 1);//set points of other student by 1 more point
       return otherStudent.points;//return he otherstudents point
   }

}

CHECKING THE METHODS USING Classroom.java

NOTE: HOPE YOU HAVE Classroom.java FILE , THE CODE INSIDE THE CLASSROOM.JAVA MAY BE DIFFERENET

public class Classroom {
   public static void main(String[] args) {
       Student s1 = new Student("StudentName1");// creating a student with name StudentName1
       s1.setPoints(100);// set points
       System.out.println("Student name using getName method " + s1.getName());
       System.out.println("Student point using getPoints method " + s1.getPoints());

       Student other = new Student("OtherName");
       other.setPoints(99);
       System.out.println("Other Student name using getName method " + other.getName());
       System.out.println("Other Student point using getPoints method " + other.getPoints());

       s1.utorStudent(other);
       System.out.println("other students point: "+other.getPoints());
       System.out.println("Total number of students: "+other.studentCount);
   }
}
