很简单的一段代码，也知道是哪里错误，就是不明白为什么，希望大侠们指教指教
当调用main.drop(6000) 就报错了， drop(int times)方法里调用了自身的方法，这样为什么会导致报错呢
```public class Main {
private double TotalHeight = 100;
private double CurHeight = 50;
public void drop(int times) {
if ((times - 1) == 0) {
return;
}
setTotalHeight(getTotalHeight() + 2 * getCurHeight());
setCurHeight(getCurHeight() / 2);
drop(times - 1);
}
public double getTotalHeight() {
return TotalHeight;
}
public void setTotalHeight(double totalHeight) {
TotalHeight = totalHeight;
}
public double getCurHeight() {
return CurHeight;
}
public void setCurHeight(double curHeight) {
CurHeight = curHeight;
}
public static void main(String[] args) {
Date startDate = new Date();
Main main = new Main();
main.drop(50000); // 此处达到6000的时候就报标题上面的错误
System.out.println("Total height is " + main.getTotalHeight());
System.out.println("Current height is " + main.getCurHeight());
}
}
