Linear / Sequential Search Example in Java

Quick Java code snippet to show Linear / Sequential Search.

import java.util.Scanner;

public class LinearSearchExample {

	public static void main(String args[]) {
		int i, totalCount, search, inputArray[];

		Scanner scanner = new Scanner(System.in);

		System.out.println("Enter number of elements");
		totalCount = scanner.nextInt();
		inputArray = new int[totalCount];

		System.out.println("Enter " + totalCount + " integers");

		for (i = 0; i < totalCount; i++) {
			inputArray[i] = scanner.nextInt();
		}

		System.out.println("Enter value to find");
		search = scanner.nextInt();

		for (i = 0; i < totalCount; i++) {
			// Element found
			if (inputArray[i] == search) {
				System.out.println(search + " is present at location "
						+ (i + 1) + ".");
				break;
			}
		}

		// Element not in the input array
		if (i == totalCount) {
			System.out.println(search + " is not present in array.");
		}
	}
}
