Answer 1

import java.util.Scanner;

public class LinearSearching {

// For linear searching and returning results.

static String linearSearch(int[ ] array, int searchElement) {

for (int i = 0; i < array.length; i++)

if (array[i] == searchElement)

return "Search Successful,\nFound At Index - " + i + ".";

return "Search Unsuccessful.";

}

public static void main(String[ ] args) {

// Declaration of array of 10 elements.

int[ ] array = new int[10];

// Accepting number into the array.

System.out.println("Enter 10 numbers - ");

Scanner sc = new Scanner(System.in);

for (int i = 0; i < array.length; i++)

array[i] = sc.nextInt( );

// Accepting the search element and printing the results.

System.out.print("Enter the number to be searched - ");

System.out.println(linearSearch(array, sc.nextInt( )));

}
