Phase 1:

Create a separate class each in a .java file to represent vehicle accidents data occurred in a country, an accident, a vehicle and a driver.

The vehicle accidents class has attributes to store a country name and a list of published accidents data by the DfT in that country. The accident class keeps the details about collision road location (within urban area, highway), date/time, the vehicles associated and the number of casualties.

Note: Use the Date class available in java.util package to represent the accident data/time.

Each vehicle has a number and a driver. The driver class records the driver's name, age, gender and his/her license issue date. The reported vehicle accidents are of the following types:

1.     Single vehicle accident: This is a type of road traffic accident in which only one vehicle is involved. A majority of these types of crashes are collisions with fallen debris, a pole, a tree, a wall, and collisions with animals.

2.     Rear-end accident: A traffic accident where a vehicle crashes into the vehicle in front of it. Sudden deceleration (slowing down or braking) is a common cause of such accidents.

3.     Side-impact accident: These accidents, also known as broadside or T-bone collisions, are where the side of one or more vehicles is impacted. These crashes commonly occur at intersections and parking lots. The results from a side-impact collision can be severe but can vary depending on where the vehicle is struck.

4.     Head-on accident: This type of accident is when the front ends of two vehicles hit each other in opposite directions. Being aware of traffic signs, street conditions, and staying in your lane play a critical role in avoiding these types of accidents.

Create a class for each vehicle accident type and define necessary attributes and methods.

Each class must store its state in private variables. It should use a static variable to maintain a count of all instances of the class. For All required access is done through public methods. The public methods which you must implement allow the user to do the following:

I NEED HELP WITH PHASE 2 (I NEED SOMEONE TOADD ON MY CODE FOR PHASE 2)

THIS IS PHASE 2 IVE DONE SOME IN MY CODE BUT I NEED HELP TO CONTINUE

-         Initiate, get, and set the state of any created object.

-         Create a new vehicle accident data object for a given country.

-         Add a reported accident type to the list of accidents if is not already in the list of the accident.

-         Find and display the most frequent accident type from the collected data.

-         Display percentage of causalities in accidents involving drivers over age 65.

-         Compare the number of accidents that occur within built-up areas to those accidents that occur on highways.

-         Display the country name and accidents list which shows the accident details for the drivers involved in accidents having a driver's license issued after 2015.

-         Dump the vehicle accident data structure into text.

-         Save the information of the vehicle accident data structure into a file.

If the user attempts do an operation that will violate the state of objects, you must check for it. In that case, the operation should be ignored and the application should give back an error message.
