java生成word文档的问题

一、java生成word文档的问题

Jacob解决Word文档的读写问题收藏

Jacob是Java-COM Bridge的缩写，它在Java与微软的COM组件之间构建一座桥梁。使用Jacob自带的DLL动态链接库，并通过JNI的方式实现了在Java平台上对COM程序的调用。Jacob下载的地址为：

(1)将解压包中的jacob.dll（x86常用,x64)拷到jdk安装目录下的jre\bin文件夹或windows安装路径下的WINDOWS\system32文件夹下

(2)将jacob.jar文件拷到classpath下即可

对于”java.lang.UnsatisfiedLinkError: C:\WINDOWS\system32\jacob-1.14.3-x86.dll:由于应用程序配置不正确，应用程序未能启动。重新安装应用程序可能会纠正”这个问题,可以通过

重新下载Jacob的jar及dll文件(最好版本比现在的低,如1.11)解决

实例制作（主要功能：标题制作，表格制作，合并表格，替换文本，页眉页脚,书签处理）:

二、Android studio怎么生成javadoc

.Androidstudio下载javadoc插件。

选择要生成注释的工程，模块或者Java文件，右键选择如下图的，JavaDocs->Create JavaDocs for all elements

选中你要生成javadoc的模块或者工程，点击Android studio导航栏上Tools->Generate JavaDoc

1.选择要生成javadoc的范围，是整个工程，还是某个模块；

2.javadoc的生成文件路径，新建一个文件夹；

3.Other command line arguments:设置

-encoding utf-8-docencoding utf-8-charset utf-8-bootclasspath“E:\tools\adt-bundle-windows-x86_64-20140624\sdk\platforms\android-22\android.jar”;”C:\Program Files\Java\jdk1.8.0_45\jre\lib\rt.jar”

注意如果是用的jdk1.8必须加上”C:\Program Files\Java\jdk1.8.0_45\jre\lib\rt.jar”，否则会报错：

com.sun.tools.doclets.internal.toolkit.util.DocletAbortException:com.sun.tools.javac.code.Symbol$CompletionFailure:找不到java.lang.FunctionalInterface的类文件

三、用java编写一个统计投票结果程序

1、先定义一个学生的对象，里面有名字，和票数两个属性，再定义一个排序函数，返回值为数组，就是取得三个数的数组，打印输出，或者可以自己想一个更加面向对象的结构实现，在简单问题上多用面向对象去思考问题。

2、public static void main(String args[]){

3、Scanner in= new Scanner(System.in);

4、int cj, yxsum= 0, tgsum= 0, bjgsum= 0;

5、while((cj= in.nextInt())!= 0){

6、当编辑并运行一个Java程序时，需要同时涉及到这四种方面。使用文字编辑软件（例如记事本、写字板、UltraEdit等）或集成开发环境（Eclipse、MyEclipse等）在Java源文件中定义不同的类；

7、通过调用类（这些类实现了Java API）中的方法来访问资源系统，把源文件编译生成一种二进制中间码，存储在class文件中，再通过运行与操作系统平台环境相对应的Java虚拟机来运行class文件，执行编译产生的字节码，调用class文件中实现的方法来满足程序的Java API调用。
