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。
先第一种，为了解题而解题。
==== Main.java ====
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) {
Main main = new Main();
main.drop(2);
System.out.println("Total height is " +
main.getTotalHeight());
System.out.println("Current height is " +
main.getCurHeight());
}
}
==== 然后是第二种 =====
==== Main.java ====
package main;
import javax.swing.JFrame;
import panel.BallPanel;
import time.Delay;
public class MainFrame extends JFrame {
public MainFrame(String title) {
super(title);
}
public static void main(String[] args) {
Delay delay = new Delay();
MainFrame frame = new MainFrame("Hello JFrame");
BallPanel ballPanel = new BallPanel();
frame.add(ballPanel);
frame.setSize(500, 500);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
delay.initDelay();
ballPanel.setDelay(delay.getDelay());
ballPanel.loopDrop(0);
}
}
==== Delay.java ====
package time;
public class Delay {
public void initDelay() {
int g = 10;
int i = 0;
double s, t, t0 = 0.0;
delay = new int[100];
for (s = 100; s 10100; s += 100) {
t = Math.sqrt(2 * s / g);
delay[i++] = (int) ((t - t0) * 100);
t0 = t;
}
}
public int[] getDelay() {
return delay;
}
private int delay[];
}
==== BallPanel.java ====
package panel;
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JPanel;
public class BallPanel extends JPanel {
public BallPanel() {
super();
}
public void paint(Graphics g) {
g.clearRect(0, 0, this.getWidth(), this.getHeight());
g.setColor(Color.BLUE);
g.fillOval(250, ballCenter, 30, 30);
}
public void loopDrop(int height) {
int i;
if (this.height == height) { // At bottom
for (i = 0; i targetHeight; i += MUL) {
ballCenter = this.height - i;
this.repaint();
try {
Thread.sleep(delay[(targetHeight - i - 1) / MUL]);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
loopDrop(this.height - i);
} else { // At top
for (i = height; i this.height; i += MUL) {
ballCenter = i;
this.repaint();
try {
Thread.sleep(delay[(i - height) / MUL]);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
targetHeightV = targetHeightV / 2;
targetHeight = targetHeightV;
if (targetHeight != 0) {
loopDrop(i);
}
}
}
public void setDelay(int delay[]) {
this.delay = delay;
}
private int extracted() {
return 100 * MUL;
}
private int targetHeight = extracted();
private int targetHeightV = extracted();
private int ballCenter = 0;
private int height = extracted();
private int delay[];
private final int MUL = 4;
}
其实所谓的第二种，是用的JFrame在JPanel上画图，直观的展示出来每次弹起来的效果。因为100像素实在太小了，所以我做了一个变量MUL，相
当于是等比例扩大的效果。问题就是弹不到10次距离就用光了，所以。。。。。权当娱乐了。。当然可以等比例在放大，例如100M看成是10000像素，这
样能多弹几次。这个程序，最后球就在那里不动了，程序不会自己退出。
你的分给的太多了，1000千行代码，给5分就可以了。
import java.io.*;
public class HaHa {
public static void main(String[] args) throws Exception {
StringBuilder sb = new StringBuilder();
sb.append("public class Test {\n");
sb.append("\tpublic static void main(String[] args) {\n");
for(int i = 0; i 1000; i++) {
sb.append("\t\tSystem.out.println(\"\u7f8e\u6b7b\u4f60\u4e86\uff0c50\u5206\u63621000\u884c\u4ee3\u7801\uff01\");\n");
}
sb.append("\t}\n");
sb.append("}\n");
FileWriter out = new FileWriter("Test.java");
out.write(sb.toString());
out.close();
}
}
大的java文件一样可以编译的 我曾经见一强人写的8000行的类 一样运行 文件上传的大小是网站根据自己的实际而定的 并不存在固定值
上面这位仁兄的代码我调可很长时间才调好，做事情真不负责任，既然要贴出来就应该是拿来就能用的。哎！！我把改好的给你
