Write a program to accept the names of 10 cities in a single dimensional string array and their STD (Subscribers Trunk Dialling) codes in another single dimension integer array. Search for the name of a city input by the user in the list. If found, display "Search Successful" and print the name of the city along with its STD code, or else display the message "Search unsuccessful, no such city in the list".

Write a program to accept the names of 10 cities in a single dimensional string array and their STD (Subscribers Trunk Dialling) codes in another single dimension integer array. Search for the name of a city input by the user in the list. If found, display "Search Successful" and print the name of the city along with its STD code, or else display the message "Search unsuccessful, no such city in the list".

Program:

import java.util.Scanner;

public class RAnsariStdCodes
{
    public static void main(String args[]) {
        final int SIZE = 10;
        Scanner in = new Scanner(System.in);
        String cities[] = new String[SIZE];
        String stdCodes[] = new String[SIZE];
        System.out.println("Enter " + SIZE +
                 " cities and their STD codes:");

        for (int i = 0;  i < SIZE; i++) {
            System.out.print("Enter City Name: ");
            cities[i] = in.nextLine();
            System.out.print("Enter its STD Code: ");
            stdCodes[i] = in.nextLine();
        }

        System.out.print("Enter name of city to search: ");
        String city = in.nextLine();

        int idx;
        for (idx = 0;  idx < SIZE; idx++) {
            if (city.compareToIgnoreCase(cities[idx]) == 0) {
                break;
            }
        }

        if (idx < SIZE) {
            System.out.println("Search Successful");
            System.out.println("City: " + cities[idx]);
            System.out.println("STD Code: " + stdCodes[idx]);
        }
        else {
            System.out.println("Search Unsuccessful");
        }
    }
}

Output:

Enter 10 cities and their STD codes:
Enter City Name: Kolkata
Enter its STD Code: 001
Enter City Name: Delhi
Enter its STD Code: 002
Enter City Name: Chennai
Enter its STD Code: 003
