PLEASE HELP ASAP in java please

The Springfork Amateur Golf Club has a tournament every weekend. The club president has asked you to design two java programs. (1) A java program that will read each player's name and golf score as keyboard input, and then save these as records in a file named golf.dat. (Each record will have a field for the player's name and a field for the player's score.) (2) A java program that reads the records from the golf.dat file and displays them. It also displays the name of the player with the best (lowest) golf score.

Explanation / Answer

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;

public class PlayerStore {
public static void main(String args[]){
  
   saveFile();
   readFile();
}
  
public static void readFile () {

   String fileName = "players.dat";

   // This will reference one line at a time
   String line = null;

   try {
       // FileReader reads text files in the default encoding.
       FileReader fileReader = new FileReader(fileName);

       // Always wrap FileReader in BufferedReader.
       BufferedReader bufferedReader = new BufferedReader(fileReader);

       while ((line = bufferedReader.readLine()) != null) {
           System.out.println(line);
           //String lineArray[] = line.split(" ");
       }
//       Always close files.
       bufferedReader.close();
   } catch (FileNotFoundException ex) {
       System.out.println("Unable to open file '" + fileName + "'");
   } catch (IOException ex) {
       System.out.println("Error reading file '" + fileName + "'");
       // Or we could just do this:
       // ex.printStackTrace();
   }

}
   public static void saveFile () {

   try {
   FileOutputStream fos = new FileOutputStream ("players.dat", true);
   DataOutputStream dos = new DataOutputStream (fos);
     
   do{
       Scanner scanner=new Scanner(System.in);
       System.out.print("Player Name :");
   String playerName=scanner.nextLine();
  
   System.out.print("Player Score :");
   int gulfScore=scanner.nextInt();
  
   dos.writeUTF(playerName+" "+gulfScore+" ");
   System.out.print("Enter any More(y for 1/n for 0) :");
   int choice = scanner.nextInt();
           if (choice == 0) {
               break;
           }
   }while(true);
   dos.close();
   fos.close();
   }
   catch (IOException ioe) {
  
   }

   }
}

out put :

Player Name :dd
Player Score :34
Enter any More(y for 1/n for 0) :1
Player Name :erd
Player Score :45
Enter any More(y for 1/n for 0) :0
