Question

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 compile error because the Fruit class does not have a no-arg
constructor.
The program has a runtime error on Line 3 because the Fruit class does not have
a no-arg constructor.
The program has a compile 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 4 because the Fruit class does not
implement the java.lang.Comparable interface and the Fruit objects are not

Complete the isExact Reverse() method in Reverse.java as follows: The method takes two Strings x and y as parameters and returns a boolean. The method determines if the String x is the exact reverse of the String y. If x is the exact reverse of y, the method returns true, otherwise, the method returns false. Other than uncommenting the code, do not modify the main method in Reverse.java. Sample runs provided below. Argument String x "ba" "desserts" "apple" "regal" "war" "pal" Argument String y "stressed" "apple" "lager" "raw" "slap" Return Value false true false true true false
