Need Help for one java class. MAP please assume that the spot and thing class work
class Map
A Map represents all the spots and things in a simulation, and provides some support methods for them as well. You will likely need to create the enumerations, interfaces, and many of the Thing classes before you can pull them all together with the Map class.
Fields
protected Spot[][] floorplan protected Thing[] things protected java.io.PrintStream log
Methods
Map(String filename, PrintStream log). Reads the given file to construct a map and all spots/things on it. Any messages (such as safety or death messages) from this map will be sent to log.
any "map file" that is named in the first argument ("String filename") is assumed to have the same number of characters in each line, each line ends with a " " character, and each character is assumed to be one of our valid characters (see Map Representations). If any of these assumptions is invalidated, or the file doesn't even exist, your program does not need to function (behavior is undefined). You may add throws IOException to your method signature as necessary. Manual Inspection Criteria (5%) : Well documented, elegant solution to reading the map text files. (See more details in the grading section of this project specification).
public boolean onMap(Coord c). Answers if the given Coord is on this Map. public Spot spotAt(Coord c). Returns the Spot at the given Coord, if present (from the floorplan). If the Coord isn't on the map, this method will return null. public int peopleRemaining(). Returns how many people are still trying to escape. Status.Safe and Status.Dead people don't count, but Status.Escaping people do get counted. Threats don't count either, of course. public void addThing(Thing a). Occasionally new things should be added (usually these are threats that have spawned more spots of slime or haze). Accept a new Thing (assumed to be on the map), and cause the things field to be one spot longer, with this new one at the end. Remember, arrays can't change length. How will you get around this? (you can't change the type of the field)
Manual Inspection Criteria (5%) : well-documented description of your approach to dealing with growing arrays (and a matching implementation).
public Thing[] thingsAt(Coord c). Return an array of all Thing values found at the given coordinate. Preserve the order of original appearance. If c isn't on the map, or no Thing is there, an empty array is returned. public boolean canLookThroughLocation(Coord c). Considering the spot and all things on that spot, can a person look through this location? If c isn't on the map, false is returned.This method is already created in spot!! public boolean canPassThroughLocation(Coord c). Considering the spots and all things on that spot, can a person pass through this location? If c isn't on the map, false is returned. This method is already created in spot!!
public void iterate(). For all Thing items we saw in their original order of discovery/spawning, allow them to perform an action by calling their doAction() method. This may alter the map by changing Thing positions or adding new Things.
after allowing all things to make their moves, the message "map:" must be sent to log, and then this map's toString() representation must also be sent to the log. if a GreenSlime is spawned into a spot containing people, it immediately kills them; it doesn't need to wait for the next iteration. Note, this doesn't count as taking an action (do not call doAction on the spawned threat).
@Override public String toString(). Returns a String that represents one entity per location. When more than one thing exists at a location, here is the order of preference (higher in the list is chosen):
Wall Haze GreenSlime any Person (prefer the last in the map's things array) Exit, Open, or Sign spots (any direction)
