Searching an Array For an Exact Match in Java | In this post, we will discuss searching an array for an exact match in Java. First, let us understand it through an example:-
Example-1:-
String citiesInMichigan[ ] = {“Acme”, “Albion”, “Detroit”, “Watervliet”, “Coloma”, “Saginaw”, “Richland”, “Glenn”, “Midland”, “Brooklyn”};
String to search:- Glenn
The given string Glenn is present in the citiesInMichigan.
Example-2:-
String fruits[ ] = {“apple”, “mango”, “banana”, “cherry”, “strawberry”, “muskmelon”, ” watermelon”}
String to search:- custard apple
The given string custard apple is not present in the fruits.
Program for Searching an Array For an Exact Match in Java
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String[] cities = { "Bangalore", "Mysore",
"Bhadravati", "Dharwad",
"Belgaum" };
Boolean found = false;
System.out.print("Enter the city name to find: ");
String city = scan.nextLine();
for (int i = 0; i < cities.length; i++) {
if (cities[i].equals(city)) {
found = true;
break;
}
}
if (found) {
System.out.println("The given city " +
city + " is present in the array");
} else {
System.out.println("The given city " +
city + " is not present in the array");
}
scan.close();
}
}Output:-
Enter the city name to find: Delhi
The given city Delhi is not present in the array
Enter the city name to find: Bangalore
The given city Bangalore is present in the array
Explanation of the above program for searching an array for an exact match in Java is as follows:-
Step-1:- Import the scanner class as we need to take input from the user
Step-2:- In the main class and main method create an array with the cities.
Step-3:- Take a string input from the user which is to be found in the given array.
Step-4:- Use for loop to check whether the string is present in the array or not, for i is equal to 0 and lesser than cities.length increment i.
Step-5:- If the string equals array[i] increment found.
Step-6:- Else return “the string not found”.
