Exercise 1. Write the class Vehicle with three attributes registrationNumber (int), maxVelocity (double) and value (double).

- Add a constructor with three parameters to initialize the three attributes.

- Add a get method to return the data fields.

- Add a toString() method to return all the information of the vehicle.

In the main method

Create an arrayList of three objects of type Vehicle.

b- Order the vehicles based on the registrationNumber and display them.

c- Create a linkedList of five objects of type Vehicle.

d- Order the linkedList based on value and display them.

e- Order the linkedList based on registrationNumber in descending order.

Exercise 2

Implement a class that maintains a list of the top ten performers in a video game. An entry on the list consists of a name and score, and the list is kept sorted in descending order of scores. Here is an example of such a list when it has only four elements. Spike 120, Whiz 105, G-Man 99, JediMaster 95.

Use a class based on linked lists. The class should have:

-a constructor that sets up an empty list,

- a void insert(String name, int score) method that adds a name and a score pair to the list.

The insert method puts the entry in the proper position so that the list stays sorted by score. The list should have a maximum size of 10. After the list has 10 elements, an attempt to add a name with a score that is less than or equal to the minimum score on the list is ignored, and adding a score that is greater than the minimum score causes an entry with the minimum score to be dropped from the list
