Explanation / Answer

LastNameSearch.java

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

public class LastNameSearch {

  
   public static void main(String[] args) throws FileNotFoundException {
       File file = new File("D:\studentdata.txt");
       Scanner fileData = new Scanner(file);
       Scanner scan = new Scanner(System.in);
       System.out.println("Enter ast name you wish to search for: ");
       String lastName = scan.next();
       boolean found = false;
       while(fileData.hasNextLine()){//checking next line available
           String record = fileData.nextLine(); //reading each line from file
           String recordLastName = record.split("\s+")[0]; //getting last name from each line
           if(lastName.equalsIgnoreCase(recordLastName)){ //checking matching with input or not
               System.out.println("Record Found.");
               System.out.println(record);
               found = true;
           }
       }
       if(!found) {
           System.out.println("Record not found");
       }
       }

}

Output:

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

public class LastNameSearch {

  
   public static void main(String[] args) throws FileNotFoundException {
       File file = new File("D:\studentdata.txt");
       Scanner fileData = new Scanner(file);
       Scanner scan = new Scanner(System.in);
       System.out.println("Enter ast name you wish to search for: ");
       String lastName = scan.next();
       boolean found = false;
       while(fileData.hasNextLine()){//checking next line available
           String record = fileData.nextLine(); //reading each line from file
           String recordLastName = record.split("\s+")[0]; //getting last name from each line
           if(lastName.equalsIgnoreCase(recordLastName)){ //checking matching with input or not
               System.out.println("Record Found.");
               System.out.println(record);
               found = true;
           }
       }
       if(!found) {
           System.out.println("Record not found");
       }
       }

}
