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
}
}
