基于JAVA的ATM模擬系統(tǒng)

1、使用JAVA設(shè)計(jì)一個(gè)ATM程序，實(shí)現(xiàn)自動(dòng)取款機(jī)存款、取款、查詢等功能。程序：(1) 【Account】package atm ;/* * 賬戶類:包含兩種賬戶類型->1.儲(chǔ)蓄賬戶 2.信用賬戶 */public abstract class Account /屬性protected long id;protected String password;protected String name;protected String IDcardid;protected int accountType;protected double balance;/構(gòu)造方法public Account()s
