Question

I am wanting to know how to write guessing game program in java that prompts the use to enter a capital for a each of 50 states, one state at a time. Upon receiving the user input, the program reports whether the answer is correct or incorrect. Assume 50 states and their capitals are stored in a two-dimensional array. Attached is a copy of the two-dimensional array that can be copied into your program. The user's answer is not case sensitive.

Sample run:

What is the capital of Alabama? Phoenix

Your answer is incorrect.

What is the capital of Alaska? Juneau

Your answer is correct.

What is the capital of Arizona? phoenix

Your answer is correct.

Answer :

import java.util.*;

class Main {

public static void main(String[] args) {

//states and capitals are declared

String[][] stateCapital = {

{"Alabama", "Montgomery"},

{"Alaska", "Juneau"},

{"Arizona", "Phoenix"},

{"Arkansas", "Little Rock"},

{"California", "Sacramento"},

{"Colorado", "Denver"},

{"Connecticut", "Hartford"},

{"Delaware", "Dover"},

{"Florida", "Tallahassee"},

{"Georgia", "Atlanta"},

{"Hawaii", "Honolulu"},

{"Idaho", "Boise"},

{"Illinois", "Springfield"},

{"Indiana", "Indianapolis"},

{"Iowa", "Des Moines"},

{"Kansas", "Topeka"},

{"Kentucky", "Frankfort"},

{"Louisiana", "Baton Rouge"},

{"Maine", "Augusta"},

{"Maryland", "Annapolis"},

{"Massachusettes", "Boston"},

{"Michigan", "Lansing"},

{"Minnesota", "Saint Paul"},

{"Mississippi", "Jackson"},

{"Missouri", "Jefferson City"},

{"Montana", "Helena"},

{"Nebraska", "Lincoln"},

{"Nevada", "Carson City"},

{"New Hampshire", "Concord"},

{"New Jersey", "Trenton"},

{"New York", "Albany"},

{"New Mexico", "Santa Fe"},

{"North Carolina", "Raleigh"},

{"North Dakota", "Bismarck"},

{"Ohio", "Columbus"},

{"Oklahoma", "Oklahoma City"},

{"Oregon", "Salem"},

{"Pennsylvania", "Harrisburg"},

{"Rhode Island", "Providence"},

{"South Carolina", "Columbia"},

{"South Dakota", "Pierre"},

{"Tennessee", "Nashville"},

{"Texas", "Austin"},

{"Utah", "Salt Lake City"},

{"Vermont", "Montpelier"},

{"Virginia", "Richmond"},

{"Washington", "Olympia"},

{"West Virginia", "Charleston"},

{"Wisconsin", "Madison"},

{"Wyoming", "Cheyenne"}

};

//scanner class to read the inputs from user

Scanner scan = new Scanner(System.in);

//loop iterate through each row of state and capital, 50 times

for (int x = 0; x < stateCapital.length; x ++) {

//make one subarray to iterate through state and capitals of particular row

String subStateCapital[] = stateCapital[x];

for (int y = 0; y < subStateCapital.length-1; y ++) {

String stCp = subStateCapital[y];

System.out.print(String.format("What is the capital of %s?",stCp));

//if capital entered is correct then save as true, it will not case sensitive

boolean bool =scan.next().equalsIgnoreCase(subStateCapital[1]);

//print the result according to value of bool

if(bool){

System.out.println("Your answer is correct");

}

else {

System.out.println("Your answer is incorrect");

}

}

}

}

}
