import java.util.Scanner;

public class StringSearch {
    public static void main(String[] args) {
        String city[] = { "Delhi", "Lucknow", "Mumbai", "Kanpur" };
        String userCity;
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter city name you want to search in list: ");
        userCity = scanner.next();
        int i = 0;
        int flag = 0;
        while (i < city.length) {

            if (userCity.equalsIgnoreCase(city[i])) {
                flag = 1;
                break;
            } else {
                flag = 0;
                i++;
            }
        }
        if (flag == 1) {
            System.out.println("City found");
        } else {
            System.out.println("Try another city");
        }
    }
}

Description: We have taken a String array of city.User will input its city and for searching we used userCity.equalsIgnoreCase(city[i])). EqualsIgnoreCase() method is used to search without caring of case. you can also use equals() method if string case is considered.
