Consider the following partially implemented class.

#2

public class Quiz {

private static int id = 1;
private int questionCount;

public Quiz(int questionCount) {
    this.questionCount = questionCount;
}

public int getId() {
    return id;
}

public void incrementId() {
    id++;
}

public int getQuestionCount() {
    return questionCount;
}

} Now, consider the following usage of the aforementioned class.

Quiz q1 = new Quiz(10); Quiz q2 = new Quiz(15); q2.incrementId();

System.out.println(q1.getId()); System.out.println(q2.getId()); System.out.println(q1.getQuestionCount()); System.out.println(q2.getQuestionCount());

What will be printed to the console?
