Solution: Required language is java below is the implementation of above question, which follows all the instruction as asked in question.Code, Place.java: public class Place { // Initiating attributes private String city; private String state; // Default constructor that initialize city and state to default values public Place(){ } // Overloaded constructor to initialize city and state to parameter values public Place(String city, String state){ this.city = city; this.state = state; } // Copy constructor to initialize city and state to same values as p's city and state public Place(Place p){ city = p.city; state = p.state; } // setter method to set city to parameter value public void setCity(String city){ this.city = city; } // setter method to set state to parameter value public void setState(String state){ this.state = state; } // getter method to return city public String getCity() { return city; } // getter method to return state public String getState() { return state; } // Method to return state initials, if state not found, return default value of "Unknown" public String getStateInitials() { // based on value of state (case-insensitive), return the corresponding state initials if(state.equalsIgnoreCase("Maryland")) return "MD"; else if(state.equalsIgnoreCase("California")) return "CA"; else if(state.equalsIgnoreCase("Florida")) return "FL"; else if(state.equalsIgnoreCase("Ohio")) return "OH"; // similarly, add more states using else if else // no match, return "Unknown" return "Unknown"; } // method to return true if obj is an object of Place class and returns true if state and city of Place is same as state and city of obj(case-insensitive) public boolean equals(Object obj){ // validate obj is an object of Place if(obj instanceof Place){ Place p = (Place)obj; // case obj to Place return city.equalsIgnoreCase(p.city) && state.equalsIgnoreCase(p.state); } return false; // obj is not an object of Place } // method to return String representation of Place's state and city public String toString(){ return "State: " + state + ", City: " + city; } public static void main(String []args){ // test the Place class Place p1 = new Place("Miami", "Florida"); Place p2 = new Place("New York City", "New York"); System.out.println(p1); System.out.println("State initials: " + p1.getStateInitials()); System.out.println(p2); System.out.println("State initials: " + p2.getStateInitials()); }}Code snip: Output snip:

city
state

A Place will have these methods:

default constructor
overloaded constructor
copy constructor
setters and getters for all attributes
get State initials – get the abbreviation for the state. You may use a utility or a case structure. (FYI, you don’t have to put all 50 states in, at least have what you have in the file. Pick a few and test.
copy()
equals()
toString()
2. A FunPlace class.

A FunPlace will have these attributes:

name
type (Example house, amusement park, corn maze, escape room)
price
Place - this will be of the Place class (Aggregation – a class is an attribute inside another class)

A FunPlace will have these methods:

default constructor
overloaded constructor that allows name, type, price and a Place object to be passed in
overloaded constructor that allows name, price Place
copy constructor
all getters
all setters
equals()
copy() method
toString() - this will include its Place.
