Hi guys, I have this code and when I try to compile and run it gives me an <identifier> expected error.

The code with the irrelevant parts taken out.

package ACCOUNT;

import java.util.Scanner;
import java.util.GregorianCalendar;
import javax.swing.*;

class Bank{

static private double bal;   //Account balance
static int withdraw;      //amount of times withdrawn 

static void setBal(double amount){bal = amount;}
static double getBal(){return bal;}

public static void main(String[] args){

class Charge extends Bank{
double fee = Bank.withdraw * 0.10;
double tempbal = Bank.getBal();
double amount = tempbal - fee ;
when I run it points to the line Bank.setBal(amount) and says <identifier> expected

can someone help?
