JAVA ATM剧情文字对话操作系统

分别开两个类：

效果如图：

第一个类：

package ATMSystem;

public class Account {
    private String cardId;//账号ID
    private String userName;//用户名称
    private String passWord;//用户密码
    private double money;//剩余金额
    private double quotaMoney;//每次取现额度

    public void setCardId(String cardId) {
        this.cardId = cardId;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public void setPassWord(String passWord) {
        this.passWord = passWord;
    }

    public void setMoney(double money) {
        this.money = money;
    }

    public void setQuotaMoney(double quotaMoney) {
        this.quotaMoney = quotaMoney;
    }

    public String getCardId() {
        return cardId;
    }

    public String getUserName() {
        return userName;
    }

    public String getPassWord() {
        return passWord;
    }

    public double getMoney() {
        return money;
    }

    public double getQuotaMoney() {
