Reading text file with strings, double and boolean

[otorojava]

The script works but I'm having a problem reading double and boolean

import java.io.*;
import java.util.StringTokenizer;
import javax.swing.JOptionPane;

public class FileAddress
{
  public static void main(String [] args)
  { 
    String aRecord; //for record
    String accountNumber;
    String customerName;
    String customerPhone;
    double customerBalance; //account balance
    boolean accountStatus;  //true if account is active, false if not

    StringTokenizer strings;
    
    try
	{
		FileReader inStream = new FileReader("account.txt");
        BufferedReader ins = new BufferedReader(inStream);
     
      while ((aRecord=ins.readLine())!= null)
	  {
        strings = new StringTokenizer(aRecord,"?"); //toekenizer
        if (strings.countTokens() == 5) {
          accountNumber = strings.nextToken();
          customerName = strings.nextToken();
          customerPhone = strings.nextToken();
          customerBalance = strings.nextToken(); //ERROR
          customerStatus = strings.nextToken(); //ERROR
          JOptionPane.showMessageDialog(null,accountNumber); 
          JOptionPane.showMessageDialog(null,customerName+"  "+customerPhone+"  "+customerBalance);
		  
        }
      }
      ins.close();
    }
	 catch(IOException e)
	 {
       e.printStackTrace();
     }
  }
}

Ok this is what I did to fix the double variable

//Double customerBalance ;

customerBalance = strings.nextToken(); //ERROR

I changed it to

customerBalance  = Double.parseDouble(strings.nextToken());

Now, how can I resolve string to boolean? I get an error with

boolean(strings.nextToken()); //ERROR
