eclipse-java读取ppt
java中读取ppt的实现方法如下：
public class ReadFileUtils {

* @param args
* @throws Exception
*/

ReadFileUtils rf = new ReadFileUtils();
String s = "";
// s = rf.readTXT("E:/itsm文档的后缀名分析报告2.txt");
// s = rf.readPDF("E:/memcached全面剖析.pdf");
// s = rf.readEXCEL("E:/副本工作量及成本模板.xls");
// s = rf.readEXCEL2007("E:/功能点估算方案.xlsx");
// s = rf.readWORD("E:/pms中文.doc");
// s = rf.readWORD2007("E:/功能点估算方法.docx");
//s = rf.readPPT("E:/精细化管理信息系统项目汇报v1.0.ppt");
s = rf.readPPT2007("e:/精细化管理信息系统项目汇报v1.0.pptx");
System.out.println(s);
}

相关问答
Q1: 如何编写高质量的代码.ppt
编码标准：这个想必都很清楚Java代码走查ppt，每个公司几乎都有一份编码规范，类命名、包命名、代码风格之类的东西都属于其中。
代码重复：顾名思义就是重复的代码，如果Java代码走查ppt你的代码中有大量的重复代码，Java代码走查ppt你就要考虑是否将重复的代码提取出来，封装成一个公共的方法或者组件。
代码覆盖率：测试代码能运行到的代码比率，你的代码经过了单元测试了吗Java代码走查ppt？是不是每个方法都进行了测试，代码覆盖率是多少？这关系到你的代码的功能性和稳定性。
Q2: 用流读取幻灯片报java.lang.IllegalStateException，不知哪有问题？
貌似不是你的代码的问题，你的StackTrace消息里没有你的类名和代码行位置。
