I NEED JUNIT5 TESTING FOR THESE THREE CLASSES. tHE FORMAT FOR THE CODE HAS TO STAY THE SAME BUT IF SOMETHING IN IT IS WRONG PLEASE FEEL FREE TO CHANGE IT. One or two tests per thing is fine

public class Fleet implements FleetAPI {

private static final int fleetSize = 7; private Ship[] ships; private Location location;

= public Fleet() { ships = new Ship[fleetSize]; }

public void deployFleet() { for (int i = 0; i < fleetSize; i++) { ships[i] = new Ship(); location.pick(); while (check(location) >= 0) { location.pick(); } ships[i].setLocation(location); } }

public boolean operational() { for (int i = 0; i < fleetSize; i++) { if (!ships[i].isSunk()) { return true; } } return false; }

public boolean isHitNSink(Location loc) { int index = check(loc); if (index >= 0) { ships[index].sink(); return true; } return false; }

public void printFleet() { for (int i = 0; i < fleetSize; i++) { ships[i].printShip(); } }

public int check(Location loc) { for (int i = 0; i < fleetSize; i++) { if (ships[i].match(loc)) { return i; } } return -1; } }

public class Location implements LocationAPI {

} }

@Override public void fire() { Scanner sc = new Scanner(System.in); System.out.println("Enter the coordinate to fire (e.g. a1): "); String input = sc.nextLine(); y = input.charAt(0); x = Integer.parseInt(input.substring(1)); }

@Override public void print() { System.out.println(y + "" + x); } } -------------------------------------------------------------------------------
