JAVA HELP

Ask the user for an account balance. Show, in descending order, all the accounts that have a balance greater than what the user input.

Each entry is int, string, long, double, boolean (name length, name, credit card number, balance, cashback).

can an expert help use string and char (instead of byte) to display the required info from a binary file

Enter a balance\n
9000ENTER
Accounts with a balance of at least $9000.00 (sorted by balance)\n
                Name      Account Number   Balance Cash Back\n

i have this code so far

import java.io.*;
import java.util.*;
public class AccountBalance {
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter a balance");
double input = keyboard.nextDouble();
// Create an ArrayList to store Account objects
ArrayList<Account> accounts = new ArrayList<>();
try {
// Open the binary file for reading
DataInputStream inputstream = new DataInputStream(new FileInputStream("accounts-with-names.dat"));
// Read the data from the file and store it in the ArrayList
while (inputstream.available() > 0) {
int nameLength = inputstream.readInt();
byte[] nameBytes = new byte[nameLength];
inputstream.readFully(nameBytes);
String name = new String(nameBytes, "UTF-8");
long cardNumber = inputstream.readLong();
double balance = inputstream.readDouble();
boolean cashback = inputstream.readBoolean();
accounts.add(new Account(name, cardNumber, balance, cashback));
}
// Sort the accounts by balance
Collections.sort(accounts);
// Print out the accounts with balance greater than or equal to input amount
System.out.printf("Accounts with a balance of at least $%.2f (sorted by balance)%n", input);
System.out.printf("%20s%20s%10s%12s%n", "Name", "Account Number", "Balance", "Cash Back?");
int count = 0;
for (Account acc : accounts) {
if (acc.getBalance() >= input) {
System.out.printf("%20s%20d%10.2f%12s%n", acc.getName(), acc.getCardNumber(),
acc.getBalance(), acc.hasCashback());
count++;
}
}
// Print out the number of results found
System.out.printf("%d results%n", count);
// Close the input stream
inputstream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
class Account implements Comparable<Account> {
private String name;
private long cardNumber;
private double balance;
private boolean cashback;
public Account(String name, long cardNumber, double balance, boolean cashback) {
this.name = name;
this.cardNumber = cardNumber;
this.balance = balance;
this.cashback = cashback;
}
public String getName() {
return name;
}
public long getCardNumber() {
return cardNumber;
}
public double getBalance() {
return balance;
}
public boolean hasCashback() {
return cashback;
}
@Override
public int compareTo(Account other) {
return Double.compare(this.balance, other.balance);
}
}

i cannot use this part

int nameLength = inputstream.readInt();
byte[] nameBytes = new byte[nameLength];
inputstream.readFully(nameBytes);
String name = new String(nameBytes, "UTF-8");

it produces an error i need to replace it with a char method instead to bring in the data from "accounts-with-names.dat" binary file
