银行存取款多线程编程，即要实现线程同步银行存取款多线程编程：取款getbankMoney()时，要判断余额不足；存款setbankMoney()时，限制一次存款额为1.1万元；存款和取款不能同时进行，即要实现线程同步。-Bank deposit and withdrawal multithreaded programming, that is, to achieve multi-threaded programming the thread synchronization Bank Teller: Teller getbankMoney () to determine the balance is less　deposits setbankMoney (), limit the time deposits of $ 1.1 million　deposits and withdrawals can not at the same time, that is, to achieve thread synchronization.
