Can someone help me figure out why is this not working.....
The program supposse to take the data i load into the hashmap from the file and look for the user enters. and suppose to output the answer based on the case. thanks
import java.io.File;
import java.util.HashMap;
import java.util.Scanner;
import javax.swing.InputMap;
public class Main {
public static int menu() {
int userChoice;
Scanner input = new Scanner(System.in);
/***************************************************/
System.out.println(" Choose from these choices ");
System.out.println(" -------------------------\n");
System.out.println("1 - Type 1 to Enter an Abbreviation of the state you would like the population for. ");
System.out.println("2 - Type 2 to Enter Name of the State you would like the population for. ");
System.out.println("3 - Type 3 to find the population for whole United States(Census 2010). ");
System.out.println("4 - Type 4 to Exit the Program.");
userChoice = input.nextInt();
return userChoice;
//Once you have the method complete you would display it accordingly in your main method as follows:
public static void main(String[] args) {
//int userChoice;
//Scanner input = new Scanner(System.in);
int userChoice = menu();
//from here I can either use a switch statement on the userchoice
//or I can use a while loop (while userChoice != the fourth selection
//using if/else statements to do my actual functions for the given choices.
File stateNames = new File("stateName.txt");
Scanner scan1 = new Scanner(stateNames).useDelimiter("[,\n\r]+");
Scanner scan = new Scanner(System.in);
HashMap<String, String> states = new HashMap<>();
String stateName;
String stateAbbrev;
/*while (scan1.hasNext()) {
stateName = scan1.next();
stateAbbrev = scan1.next();
states.put(stateName, stateAbbrev); */
do
{
int userchoice = 0;
//String stateName;
//String stateAbbrev;
int statePop;
Scanner selection = new Scanner(System.in);
userChoice = selection.nextInt();
}
while {
Switch(userchoice){
Case 1:
Scanner input = new Scanner(System.in);
String state = input.nextLine();
System.out.print("the abbreviation for " + stateName + "is " + stateAbbrev);
break;
Case2:
input1 = new Scanner(System.in);
String abbrev = InputMap.nextLine();
System.out.println(stateAbbrev + stateName);
break;
Case3:
input1 = new Scanner(System.in);
System.out.println(stateAbbrev + statePop);
break;
case 4:

}
