我就不分2个类了。下面贴出代码和结果。

public class Account{
String customerId;
String accountNo;
double balance;

public Account(String _customerId,String _accountNo,double _balance){   //构造方法1,
  this.customerId=_customerId;
  this.accountNo=_accountNo;
  this.balance=_balance;
  return;
}

public Account(String _customerId,String _accountNo){   //构造方法2
  this.customerId=_customerId;
  this.accountNo=_accountNo;
  this.balance=0;
  return;
}

public void setCustomerId(String _customerId){   //设置身份信息
  this.customerId=_customerId;
}

public String getCustomerId(){    //获取身份信息
  return this.customerId;
}

public void setAccountNo(String _accountNo){   //设置账号ID
  this.accountNo=_accountNo;
}

public String getAccount(){   //获取账号信息
  return this.accountNo;
}

public void setBalance(double _balance){ //设置初始存款
  this.balance=_balance;
}

public double getBalance(){   //获取存款信息
  return this.balance;
}

public double deposit(double savecash){    //存款
  this.balance=savecash+this.balance;
  return this.balance;
}

public double withdraw(double getcash){ //取款
  this.balance=this.balance-getcash;
  return this.balance;
}

public static void main(String [] args){
  Account a1=new Account("张三","20155251",2000);
  Account a2=new Account("张三","20155252");
  Account a3=new Account("李四","20155253",3000);
  a1.withdraw(500);
  a1.withdraw(1000);
  a2.deposit(1000);
  a3.withdraw(300);
  System.out.println(a1.getAccount());
  System.out.println(a1.getBalance());
  System.out.println(a2.getAccount());
  System.out.println(a2.getBalance());
  System.out.println(a3.getAccount());
  System.out.println(a3.getBalance());
}
}
