Question 2

Analyze the following code.

1. public class Test {

2.	public static void main(String[] args) {

3.	Fruit[] fruits = {new Fruit(2), new Fruit(3), new Fruit(1)};

4.	java.util.Arrays.sort(fruits);

5.

}

6. }

class Fruit {
private double weight;

public Fruit(double weight) {

this.weight = weight;

}
}

◦ The program has a runtime error on Line 4 because the Fruit class does not implement the java.lang.Comparable interface and the Fruit objects are not comparable.
◦ The program has a runtime error on Line 3 because the Fruit class does not have a default constructor.
◦ The program has a compile error because the Fruit class does not have a default constructor.
