a) Write a Java class Student with three fields: name, mark

and maxscore representing a student who has scored mark

out of maxscore. The class has a constructor and two

methods:

addBonus adds a given bonus score to the student’s mark;

toString returns a String summarising the current state of

the Student. You should select suitable types and

parameters for your class its constructor and methods.

b) Using your Student class from a), write an efficient

method

public Student topStudent(ArrayList cits1001) that returns

the Student object with the highest percentage score from

a given ArrayList of Students called cits1001. Write a

suitable helper method that returns a student’s mark as a

percentage rounded to the nearest integer. Javadoc

comments are not required for this question.

Solution

Student.java

import java.util.ArrayList;

public class Student {

private String name;

private double mark;

private double maxscore;

public Student(){

}

public Student(String name, double mark, double

maxmark){

this.name = name;

this.mark = mark;

this.maxscore = maxmark;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public double getMark() {

return mark;

}

public void setMark(double mark) {

this.mark = mark;

}

public double getMaxscore() {

return maxscore;

}

public void setMaxscore(double maxscore) {

this.maxscore = maxscore;
