Sequential Search Program

Sequential Search

• Sequential search is also called as Linear search.

• It checks every one of its elements one by one in sequence, until desired element is not found.

Sequential Search Program in Eclipse

• Create new java project using eclipse as follows:





• Write the code for sequential search as follows in the class:

package com.javabykiran.sequentialsearch;

import java.util.Scanner;

public class JbkSequentialSearchEx {

    public static void main(String[] args) {

	int counter, numberOfElements, item, array[];

	// To get the user input
	Scanner input = new Scanner(System.in);
	System.out.println("Enter number of elements:");
	numberOfElements = input.nextInt();
        // Creating array to store the user entered elements
	array = new int[numberOfElements];
	System.out.println("Enter " + numberOfElements + " integers");

	// Loop to store each number in array
	for (counter = 0; counter < numberOfElements; counter++)
            array[counter] = input.nextInt();

	System.out.println("Enter the search value:");
	item = input.nextInt();

	for (counter = 0; counter < numberOfElements; counter++) {
            if (array[counter] == item) {
		System.out.println(item + " is present at location " + (counter + 1));

		/* Item is found so, to come out of the loop */
		break;
            }
	}
	if (counter == numberOfElements)
            System.out.println(item + " doesn't exist in array.");
    }
}

• Now run your program as Java Application

• Enter the total number of elements on console

• Enter the integer numbers

• Enter the elements you want to search and you should get output as follows:
