Hi Timothy,

You will need Java JDK 1.5 or above, Apache POI library v3.8 or above and Eclipse 3.2 above. At first include apache poi jar file to your project.

<dependency>

    <groupId>org.apache.poi</groupId>

    <artifactId>poi</artifactId>

    <version>3.8</version>

</dependency>

Here is the sample code which will read data from Excel:

Hi Timothy Raine,

Here is the source code for your program,

import org.apache.poi.hssf.usermodel.HSSFSheet;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;
//..
FileInputStream file = new FileInputStream(new File("C:\test.xls"));
            
//Get the workbook instance for XLS file
HSSFWorkbook workbook = new HSSFWorkbook(file);
 
//Get first sheet from the workbook
HSSFSheet sheet = workbook.getSheetAt(0);
 
//Get iterator to all the rows in current sheet
Iterator<Row> rowIterator = sheet.iterator();
 
//Get iterator to all cells of current row
Iterator<Cell> cellIterator = row.cellIterator();
 
Let's consider simple excel file
We will read above xls file and prints the data.
 
try {
    
    FileInputStream file = new FileInputStream(new File("C:\test.xls"));
    
    //Get the workbook instance for XLS file
    HSSFWorkbook workbook = new HSSFWorkbook(file);
 
    //Get first sheet from the workbook
    HSSFSheet sheet = workbook.getSheetAt(0);
    
    //Iterate through each rows from first sheet
    Iterator<Row> rowIterator = sheet.iterator();
    while(rowIterator.hasNext()) {
        Row row = rowIterator.next();
        
        //For each row, iterate through each columns
        Iterator<Cell> cellIterator = row.cellIterator();
        while(cellIterator.hasNext()) {
            
            Cell cell = cellIterator.next();
            
            switch(cell.getCellType()) {
                case Cell.CELL_TYPE_BOOLEAN:
                    System.out.print(cell.getBooleanCellValue() + "tt");
                    break;
                case Cell.CELL_TYPE_NUMERIC:
                    System.out.print(cell.getNumericCellValue() + "tt");
                    break;
                case Cell.CELL_TYPE_STRING:
                    System.out.print(cell.getStringCellValue() + "tt");
                    break;
            }
        }
        System.out.println("");
    }
    file.close();
    FileOutputStream out =
        new FileOutputStream(new File("C:\test.xls"));
    workbook.write(out);
    out.close();
    
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}
 
Output
Emp Id   Name        Salary     
1.0     John        2000000.0      
2.0     Dean        420000.0       
3.0     Sam     280000.0       
4.0     Cass        6000000.0  
 
Hope this helps you.
 
Thanks,
