package com.glut.util;
/*题目：一球从100米高度自由落下，每次落地后反跳回原高度的一半；再落下，求它在 第10次落地时，共经过多少米？第10次反弹多高？ 


这个题目，下面我会贴出来两种代码。其实这个题目，我烦了简单计算，想搞得有趣味性一点，结果耽误了好几天时间，最后发现搞的也不好。




==== Main.java ====*/
public class util {
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) {
util main = new util();
main.drop(2);
System.out.println("Total height is " + main.getTotalHeight());
System.out.println("Current height is " + main.getCurHeight());
}
}
