Using POI for excel works in Java

Question

I want to read/write excel files in Java (netbeans). There are a lot of information on how to do that with APACHE POI and I know that. My question is that, where should I put poi jar files? should I extract it in my local project?

Additionally, should I download the binary or src of the poi?

Answer 1

我同意Maven是最佳选择，但是如果您没有时间研究它，只需尝试将jar文件添加到您的项目中

Answer 2

If you are using maven you only have to add this dependency to your pom.xml file

<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.15</version>
</dependency>

With this library you can process .xls and .xlsx files. If you are not using maven you should download the jar file and add it to your classpath
