How to read data from excel file one line at a time - java

i want my program to read a single line (which will contain a URL) from excel file. Go to that URL and read next line -->go to the URL untill entire file is read.
import java.io.*;
import java.util.concurrent.TimeUnit;
import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
public class readDataFromExcelFile{
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com");
driver.manage().window().maximize();
WebElement searchbox = driver.findElement(By.name("q"));
try {
FileInputStream file = new FileInputStream(new File("E://TestData.xlsx"));
XSSFWorkbook workbook = new XSSFWorkbook(file);
XSSFSheet sheet = workbook.getSheetAt(0);
for (int i=1; i <= sheet.getLastRowNum(); i++){
String keyword = sheet.getRow(i).getCell(0).getStringCellValue();
searchbox.sendKeys(keyword);
searchbox.submit();
driver.manage().timeouts().implicitlyWait(10000, TimeUnit.MILLISECONDS);
}
file.close();
} catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
}
But the above program will get all the /urls at a single time. Can you please tell me what should i modify in the code.

Clear the field before typing more text into it.
sendKeys() does just what it says: It sends a series of "user pressed key X" to the browser. So if the field already contains content, then the new keys are appended.

Why I am getting Data Provider MisMatch error when I try to read from excel file?

I am trying to do data driven testing and I am not able to figure it out why I am getting data mismatch. I am trying to automate just usernames and that is in form of string. Can you please review my code and tell me what I am doing wrong?
Below are two files. one is my main method file and one is my excel config file. I have also attached screenshot of my error. Any help would be appreciated. Thank you.

Error Screenshot:
Excel File:
You are declaring Object[][] credentials = new Object[rows][2]; but you fill only one column keeping other column empty (null). Hence the dimension of your array does not match the number of arguments your method accepts.
Fix it with changing that line to:
Object[][] credentials = new Object[rows][1];

return row;
}
}
Can you please help me to sort out this, Why am getting this error? I have declared 2 Columns and 4 Rows using for loop. But am getting cannot Get The error as cannot get the string value from Numeic Cell.
Try this:
String data;
if(cell.getCellType()==CellType.STRING)
data = cell.getStringCellValue();
else if(cell.getCellType()==CellType.NUMERIC)
data = String.valueOf(cell.getNumericCellValue());
else ...
It is a better way to retrieve the cell content as text.
Thanks to #AxelRichter, the manual show a more complete example to retrieve cell content: https://poi.apache.org/components/spreadsheet/quick-guide.html#CellContents
//try this:
DataFormatter objDefaultFormat = new DataFormatter();
FormulaEvaluator formulaEvaluator = workbook.getCreationHelper().createFormulaEvaluator();
String cellValueStr = objDefaultFormat.formatCellValue( cell , formulaEvaluator );
DataFormatter contains methods for formatting the value stored in an Cell. This can be useful when you need to get data exactly as it appears in Excel.
Supported formats include currency, SSN, percentages, decimals, dates, phone numbers, zip codes, etc.
Thanks to #AxelRichter:
DataFormatter formatter = new DataFormatter();
String text = formatter.formatCellValue(cell);

Null Pointer Exception if i try to create new Cell and write data into excel

I am trying to write title and price into excel file. I am creating columns but java game me error 'NULL POINTER EXCEPTION' at line number 48, Please help me what is main reason.But if i write at line no 48 ,sheet1.getRow(0).createCell(0).getStringCellValue('Naqash');Then no Null pointer error is showing.

int j = 0;
if(sheet1.getRow(i+1)==null){
(48) sheet1.getRow(i+2).createCell(j).setCellValue("Naqash");
sheet1.getRow(i+2).createCell(j+1).setCellValue("Zafar");
}
else{
System.out.println("Cant find the scene");
}
FileOutputStream fileout = new FileOutputStream(src);
wb.write(fileout);
}
}
}
Try to create the row and cell before you insert data into it. For example:
int rowIndex = 0;
int columnIndex = 0;
Row row = sheet1.createRow(rowIndex);
Cell cell = row.createCell(columnIndex);
cell.setCellValue("Naqash");
You can get row by getRow(index) if you have already created it before
The issue is that you never test if the cell is null!
if (cell == null)
{
System.out.println("Cell is Empty in Column:" + cols);
}
else if (cell.getCellType() == HSSFCell.CELL_TYPE_STRING)
{
//code
}
As a general matter, you should be careful while handling Cell.getCellType() function, since an empty cell could be either null or be a CELL_TYPE_BLANK.
I hope it helped.

Importing null date from Excel

I have an excel sheet from where I am reading excel cel values and importing to DB
Using Apache POI :
if (row.getCell(8) != null) {
setActualDeparture(DateUtil.getJavaDate(row.getCell(8).getNumericCellValue()));
}
The excel sheet has null on Cell 8 , so it should not import anything . but it takes dates like 1899-12-31T00:00:00
What could be the issue ?
The Row.getCell(int cellnum) returns only NULL if there is nothing stored in the file for this cell. It returns the cell if there is something stored in the file for this cell. Even if this is only a NumberFormat for example or any other information for this cell.
But there is a second method Row.getCell(int cellnum, Row.MissingCellPolicy policy) http://poi.apache.org/apidocs/org/apache/poi/ss/usermodel/Row.html#getCell%28int,%20org.apache.poi.ss.usermodel.Row.MissingCellPolicy%29 which can be used in your case.
Example:
There is nothing in A1 but there is a special NumberFormat and not General applied.

System.out.println(row.getCell(0).getNumericCellValue()); //0.0
System.out.println(row.getCell(0, Row.RETURN_BLANK_AS_NULL)); //null
FileOutputStream fileOut = new FileOutputStream("workbook.xlsx");
wb.write(fileOut);
fileOut.flush();
fileOut.close();
