Write a JAVA program to search for an element in a given list of elements (linear search).

Aim: Write a JAVA program to search for an element in a given list of elements (linear search).

Program:

import java.util.Scanner;

 

class LinearSearch 

{

  public static void main(String args[])

  {

    int c, n, search, array[];

 

    Scanner in = new Scanner(System.in);

    System.out.println("Enter number of elements");

    n = in.nextInt(); 

    array = new int[n];

 

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

 

    for (c = 0; c < n; c++)

      array[c] = in.nextInt();

 

    System.out.println("Enter value to find");

    search = in.nextInt();

 

    for (c = 0; c < n; c++)

    {

      if (array[c] == search)     /* Searching element is present */

      {

         System.out.println(search + " is present at location " + (c + 1) + ".");

          break;

      }

   }

   if (c == n)  /* Searching element is absent */

      System.out.println(search + " is not present in array.");

  }

}

Output:
