怎样将xml档案生成java程式码 xml是有格式的档案，到底里面储存了什么资料，得知道，才能办法处理
java程式码怎样生成csv档案
我来说一下大致的实现步骤，具体实现需要你自己去写了
1.检索资料，检索到的资料假定为一个list
2.你需要自己写一个objectToString之类的方法来把检索到的资料转化为一个String或StringBuffer，就是往各栏位间插",",往个记录间插"\r\n"，如此这类的转换，假定转换好的字串为strResult.
3.然后用下面的程式码写在后台来控制下载，档名那里你可以把时间格式控制好，或者用前台传过来的引数做名字。
response.setContentType("application/download;charset=UTF-8");
response.setHeader("Content-disposition","attachment;filename=\"" +new Date()+".csv\"");
Java程式码完成后，怎样生成档案？
JCreator Pro 点一下编译按钮不就行了吗，再点执行按钮就运行了
eclipse通过xml档案如何找到java程式码
一、配置指南：
1、Eclipse中类档案（*.java）自动补全配置：
Windows-preferance-java-Editor-Content Assist
面板最下端 Auto Activation 将Auto activation triggers for Java后面的文字框中的“.”替换成“abcdefghijklmnopqrstuvwABCDEFGHIJKLMNOPQRSTUVWXYZ.”（注意后面还有一个"."）
2、Eclipse中*.xml档案自动补全配置：
Windows-preferance-XML-XML Files-Editor-Content Assist
面板最上端 Auto Activation 将Prompt when these characters are inserted后面的文字框中的“=:”替换成“=:abcdefghijklmnopqrstuvwABCDEFGHIJKLMNOPQRSTUVWXYZ ”（注意后面还有一个空格）
二、使用指南：
在需要程式码自动补全的地方直接按ALT+/，就会出现类似如下图所示的效果，选择就可以啦：
java程式码生成dat档案
File filename = new File("F:\\zd.dat");
说明：dat可以改成任何副档名，是自己可以定义的，如下：
public void createFile(){path表示所建立档案的路径String path = "d:/tr/rt";File f = new File(path);if(!f.exists()){f.mkdirs();} fileName表示建立的档名；为txt型别；String fileName="test.txt";File file = new File(f,fileName);if(!file.exists()){try {file.createNewFile();} catch (IOException e) { TODO Auto-generated catch blocke.printStackTrace();}}}现在可以在d:/tr/rt 目录下找到test.txt档案
怎么生成pdf档案 java程式码
使用iText外挂，这是著名的开放原始码的站点sourcefe一个专案。网上很多例子，自己搜一下，不给你举例了。
java 怎样解析 excel生成的xml档案
java解析excel生成的xml档案的方法是使用dom4j实现的。
dom4j是一个简单的开源库，用于处理XML、 XPath和XSLT，它基于Java平台，使用Java的集合框架，全面集成了DOM，SAX和JAXP。

求一段 读出\修改 xml档案的java程式码
import .dom4j.Element;

上面是主要的包！
String xml = "";
Element _root = new DefaultElement("Business");
Element _node = _root.addElement("Output");
try {
_node.addElement("Password").addText("123");
_node.addElement("ReturnData").addText("1");

}
catch (Exception ex) {
