Question

Write a java program that presents the user with the following menu

Linear Search

Binary Search

The user can choose any of these operations using numbers 1 or 2. Once selected, the operation asks the user for an input file to be searched (the file is provided to you and is named input.txt).

If option 1 or 2 is selected, it asks the user for the search string. This is the string that the user wants the program to search in the input file. Implement two methods stubs:

1) linearSearch - takes a file and a search string as inputs, and returns a boolean signifying found or not found.

2) binarySearch - takes a file and a search string as inputs, and returns a boolean signifying found or not found.

You will develop these stubs into actual functionality in the next assignment.

Sample Output 1:

Please select from below:

1. Linear Search

2. Binary Search

Your selection: 1

Please enter the input file to searched: input.txt

Please enter the string to be searched in input.txt: RaDar

Search functionality is under maintenance. Thank you for using my search program.

Sample output 2

Please select from below:

1. Linear Search

2. Binary Search

Your selection: 90

Please select between option 1 or 2

Your selection: 2

Please enter the input file to searched: words.txt

Please enter the string to be searched in words.txt: Recoil

Search functionality is under maintenance. Thank you for using my search program.

PickYourSearch.java

import java.io.File;
import java.util.Scanner;

public class PickYourSearch {

   public static void main(String[] args) {
      
       Scanner s = new Scanner(System.in);
      
       int choice;
      
       System.out.println("Please select from below:");
       System.out.println("1.Linear Search");
       System.out.println("2.Binary Search");
      
       choice = s.nextInt();
      
       while(choice != 1 && choice != 2)
       {
           System.out.println("Your selection: " + choice);
          
           System.out.println("Please select between option 1 or 2");
          
           choice = s.nextInt();
              
       }
      
       System.out.println("Your selection: " + choice);
      
       System.out.println("Please enter the input file to search: ");
      
       String fileName = s.next();
      
       System.out.println("Please enter the string to be searched in " + fileName + ": ");
      
       String text = s.next();
      
       System.out.println("Search functionality is under maintenance. Thank you for using my search program.");
      
       s.close();
   }
  

//These are the method stubs
   public static boolean linearSearch(File f,String search_str) {
       return false;
   }
   public static boolean binarySearch(File f,String search_str) {
       return false;
   }
  
}
