How to add apache poi to java?

I am a beginner in java. I have downloaded a latest version of apache poi 3.16.
There are several jar files renamed and edited from old versions. i want to know how to set class path for the files in steps and what are all the jar files that need class path? I have imported all the jar files but it showed class not found exception in this code.

import java.io.*;
import org.apache.poi.xssf.usermodel.*;
public class CreateWorkBook 
{
   public static void main(String[] args)throws Exception 
   {
      //Create Blank workbook
      XSSFWorkbook workbook = new XSSFWorkbook(); 
      //Create file system using specific name
      FileOutputStream out = new FileOutputStream(
      new File("createworkbook.xlsx"));
      //write operation workbook using file out object 
      workbook.write(out);
      out.close();
      System.out.println("
      createworkbook.xlsx written successfully");
   }
}

Before setting the classpath for the jars create a lib folder with in your project folder and copy all the jar files in this folder. For example:

D:\Project\Java\lib

After that include this location in your path.

For setting the path and classpath you can check this link:

https://docs.oracle.com/javase/tutorial/essential/environment/paths.html

For setting the path following steps:

Go to system properties

Click on advanced system settings

Click on environment variables

If using Eclipse, follow https://stackoverflow.com/a/3280384/3940047 for instructions. This library has other dependencies that need to be imported - ensure you've done that.

com.github.virtuald » curvesapi

org.apache.poi » poi

org.apache.poi » poi-ooxml-schemas

If using Maven, modify the pom.xml to include the poi-ooxml library. Transitive dependencies are taken care of by Maven.

Please share exact exception trace and your environment details to help you further. I would not recommend to add the third party libraries to Java lib directory as it might add conflicts in future with other projects.
