关于8000行的java代码的信息

JavaWeb：一般情况整个电商项目大概有多少行代码？

一般的电商项目大概5万行左右，但是有80%是框架自带的或者自动生成的代码。

创新互联服务项目包括秦都网站建设、秦都网站制作、秦都网页制作以及秦都网络营销策划等。多年来，我们专注于互联网行业，利用自身积累的技术优势、行业经验、深度合作伙伴关系等，向广大中小型企业、政府机构等提供互联网行业的解决方案，秦都网站推广取得了明显的社会效益与经济效益。目前，我们服务的客户以成都为中心已经辐射到秦都省份的部分城市，未来相信会继续扩大服务区域并继续获得客户的支持与信任！

代码只有数字不同，如何快速打出8000行

批处理（输出到当前目录下output.txt内）

for /l %%a in (1,1,8000) do (echo asdfg%%ajkllpiuyoutput.txt)

存作.bat文件

VBS（相当于从键盘按键输入）

Dim WS,n

WScript.Sleep 5000

Set WS = CreateObject("WScript.Shell")

For n = 1 to 8000

WS.Sendkeys "asdfg" n "jkllpiuy"

WS.Sendkeys "{ENTER}"

Next

运行后五秒开始输出，请先关掉输入法，并在这之内聚焦到需要输入的窗口上

存作.vbs文件

求一Java代码，要简单的。大概一百多行的的。

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。

高分求一千行JAVA代码，题材不限~要有注释~！

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();

}

}

java文件太大会无法编译么？如果是，那么文件大小的上限是多少k?

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
