参考了别人的代码。略作修改，已经很简单了：
InfoATM.java：
public class InfoATM {
double money = 0;
public InfoATM(double cash) {
super();
this.money = cash;
}
// 存款的方法
public void save(double count) {
money += count;
}
// 取款的方法
public void draw(double count) {
money -= count;
}
public double getMoney() {
return money;
}
public void setMoney(double money) {
this.money = money;
}
}

你太强了。。很多东西你都没有做，，例如你卡里只有10元，你去取1000000，会允许？ getmoney()方法里面 sum = money + index1; 你写漏1了。 最后你在两个方法里面都没有把钱赋给你原来的money这个属性，都要添加一句：money=sum 或者是money = index + money;
