Installation

Their are two ways for installing apache jar file depending upon the type of project:

Maven Project

The dependency is to be added is as given below:

<groupId>org.apache.poi</groupId>
<version>3.12</version>
<dependency>
<artifactId>poi-ooxml</artifactId>
</dependency>
Steps to create a maven project in eclipse and add dependency
- Click on file->new->maven project
- A new window appears, Click on Next
- Select maven-archetype-webapp
- Give name of the project
- A project is formed in the workspace and a pom.xml file automatically appears
- Open this file in the existing structure of pom.xml file
- Copy apache poi dependency in pom.xml file
- Maven dependency is added when the pom.xml file is saved after copying the maven dependency.
Simple Java Project
If not using maven, then one can download maven jar files from POI download. Include following jar files minimum to run the sample code:
poi-3.10-FINAL.jar
poi-ooxml-3.10-FINAL.jar
commons-codec-1.5.jar
poi-ooxml-schemas-3.10-FINAL.jar
xml-apis-1.0.b2.jar
stax-api-1.0.1.jar
xmlbeans-2.3.0.jar
dom4j-1.6.1.jar

Classes and Methods

Workbook
It’s the super-interface of all classes that create or maintain Excel workbooks. Following are the two classes that implement this interface

HSSFWorkbook
It implements the Workbook interface and is used for Excel files in .xls format. Listed below are some of the methods and constructors under this class.
- Methods and Constructors
  HSSFWorkbook()
  HSSFWorkbook(DirectoryNode directory, boolean preserveNodes)
  HSSFWorkbook(DirectoryNode directory, POIFSFileSystem fs, boolean preserveNodes)
  HSSFWorkbook(java.io.InputStream s)
  HSSFWorkbook(java.io.InputStream s, boolean preserveNodes)
  HSSFWorkbook(POIFSFileSystem fs)
  HSSFWorkbook(POIFSFileSystem fs, boolean preserveNodes)
  where:
  directory-It is the POI filesystem directory to process from.
  fs -It is the POI filesystem that contains the workbook stream.
  preservenodes – This is an optional parameter that decides whether to preserve other nodes like macros. It consumes a lot of memory as it stores all the POIFileSystem in memory (if set).
XSSFWorkbook
It is a class that is used to represent both high and low level Excel file formats. It belongs to the org.apache.xssf.usemodel package and implements the Workbook interface. Listed below are the methods and constructors under this class.
- Classes
  XSSFWorkbook()
  XSSFWorkbook(java.io.File file)
  XSSFWorkbook(java.io.InputStream is)
  XSSFWorkbook(java.lang.String path)
- Methods
  createSheet()
  createSheet(java.lang.String sheetname)
  createFont()
  createCellStyle()
  createFont()
  setPrintArea(int sheetIndex, int startColumn, int endColumn, int startRow, int endRow)
