How can I read different datatypes from excel using #dataprovider in testNG

I am trying to get input from excel for my testcase . My input contains both string and numeric values. I know how to retrieve value for single datatype using the below code
public Object[][] readnumericvalue() throws IOException {
File src = new File("filepath");
FileInputStream fis = new FileInputStream(src);
XSSFWorkbook wb = new XSSFWorkbook(fis);
XSSFSheet sheet1 = wb.getSheetAt(1);
XSSFRow row = sheet1.getRow(0);
int rowcount = sheet1.getLastRowNum();
int columnCount = row.getLastCellNum();
Object data1[][]=new Double[rowcount+1][columnCount];
columnCount = columnCount-1;
for(int i=0;i<=rowcount;i++) {
for(int j=0;j<=columnCount;j++) {
data1[i[j]= sheet1.getRow(i).getCell(j).getNumericCellValue();
}
}
return data1;
}
I tried to read both the datatypes in single dataprovider but I don't know how to initialize 2D-array for multiple datatypes
File src = new File("");
FileInputStream fis = new FileInputStream(src);
XSSFWorkbook wb = new XSSFWorkbook(fis);
XSSFSheet sheet1 = wb.getSheetAt(0);
XSSFRow row = sheet1.getRow(0);
int rowcount = sheet1.getLastRowNum();
int columnCount = row.getLastCellNum();
Object data1[][]=new String[rowcount+1][columnCount];
columnCount = columnCount-1
for(int i=0;i<=rowcount;i++) {
for(int j=0;j<=columnCount;j++) {
Cell cell = row.getCell(j);
switch (cell.getCellTypeEnum()) {
case STRING:
data1[i][j]=sheet1.getRow(i).getCell(j).getStringCellValue();
break;
case NUMERIC:
data1[i][j]=sheet1.getRow(i).getCell(j).getNumericCellValue();
break;
}
}
}
return data1;

If you would like to accommodate both the data types in the same data provider, then you can basically define the array as an Object array.
Here's a sample.
Lets say the excel workbook looks like below
| Name | Age |
|------|-----|
| Jack | 24 |
| Jill | 23 |
| Bob | 30 |
Here's a sample code, that reads this data
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.Iterator;
public class SampleTestClass {
#Test(dataProvider = "dp")
public void testMethod(String name, int age) {
System.err.println("Name :" + name + ", Age :" + age);
}
#DataProvider(name = "dp")
public Object[][] readnumericvalue() throws IOException {
File src = new File("src/test/resources/47036541.xlsx");
FileInputStream fis = new FileInputStream(src);
XSSFWorkbook wb = new XSSFWorkbook(fis);
XSSFSheet sheet1 = wb.getSheetAt(0);
int rowcount = sheet1.getPhysicalNumberOfRows();
int columnCount = sheet1.getRow(0).getLastCellNum();
Object objects[][] = new Object[rowcount-1][columnCount];
int rowCounter = 0;
Iterator<Row> rowIterator = sheet1.iterator();
boolean firstRow = true;
while (rowIterator.hasNext()) {
Row currentRow = rowIterator.next();
if (firstRow) {
firstRow = false;
continue;
}
Iterator<Cell> cellIterator = currentRow.iterator();
int colCounter = 0;
while (cellIterator.hasNext()) {
Cell cell = cellIterator.next();
switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
objects[rowCounter][colCounter] = cell.getStringCellValue();
break;
case Cell.CELL_TYPE_NUMERIC:
objects[rowCounter][colCounter] = new Double(cell.getNumericCellValue()).intValue();
break;
}
colCounter++;
}
rowCounter++;
}
return objects;
}
}
Here's the output
Name :Jack, Age :24
Name :Jill, Age :23
Name :Bob, Age :30

Hi, I Have a Excel Sheet like above. I need to count all popular routes and print that count in No.of-Routes column on corresponding S_No row. Also I have an blank line after every S_No's. And these all popular routes are not placed in one cell(each route is one row).
I tried with below code. I'm not able to move forward,please help me.
public class PrintNoOfRoutes
{
public static void main(String args[]) throws Exception
{
List list=new ArrayList();
FileInputStream file = new FileInputStream(new File("D:/BusOperators/sample.xlsx"));
XSSFWorkbook workbook = new XSSFWorkbook(file);
XSSFSheet sheet = workbook.getSheetAt(0);
Iterator<Row> rowIterator = sheet.iterator();
rowIterator.next();
Row row = rowIterator.next();
int S_No=(int) row.getCell(0).getNumericCellValue();
System.out.println(S_No);
Iterator<Cell> cellIterator = row.cellIterator();
while(cellIterator.hasNext())
{
Cell cell = cellIterator.next();
switch(cell.getCellType())
{
case Cell.CELL_TYPE_BOOLEAN:
System.out.println("boolean===>>>"+cell.getBooleanCellValue() + "\t");
break;
case Cell.CELL_TYPE_NUMERIC:
int S_No=(int) row.getCell(0).getNumericCellValue();
System.out.println(S_No);
break;
case Cell.CELL_TYPE_STRING:
//list.add(cell.getStringCellValue());
if(c==S_No)
{
System.out.println("done");
row.getCell(6);
Row row2 = rowIterator.next();
if(cell.getStringCellValue() != null)
{
count=1;
System.out.println(count);
count++;
}
break;
}

This worked for me. This depends on a blank line to indicate when to stop counting popular routes for a particular S_No. S_No and No.Of-Routes must be numeric fields.

Filtering column in excel using java poi

I have a large excel file. I want to filter a column "Mainly used for" for values "mainly used for mobile". Then I need to store the corresponding values in the "Number Series" column in a list. I have a code to start with. However I am not able to do the filtering part and storing it to an array list. Could you please help me out here.
I did some digging and have modified the code. However I have not been able to meet my requirement. I have following problems -
*The code only selects two columns and displays their contents. Not able to filter :(
*The excel has column names with spaces. So I am getting the error. As the excel is generated by the user,
we have no control over column names. How to deal with the column name with spaces ??
*Excel has alpha-numeric values, how to deal with them?
Could you please help me out here.

reading specific column of excel into java program

I need to read specific column of an excel sheet and then declare the variables in java. The program that I have done reads the entire content of excel sheet. But I need to read a fixed column like C.
This is what I have done:
import java.io.File;
import java.io.IOException;
import jxl.Cell;
import jxl.Sheet;
import jxl.Workbook;
import jxl.read.biff.BiffException;
public class JavaApplication4
{
private String inputFile;
String[][] data = null;
public void setInputFile(String inputFile)
{
this.inputFile = inputFile;
}
public String[][] read() throws IOException
{
File inputWorkbook = new File(inputFile);
Workbook w;
try
{
w = Workbook.getWorkbook(inputWorkbook);
// Get the first sheet
Sheet sheet = w.getSheet(0);
data = new String[sheet.getColumns()][sheet.getRows()];
// Loop over first 10 column and lines
// System.out.println(sheet.getColumns() + " " +sheet.getRows());
for (int j = 0; j <sheet.getColumns(); j++)
{
for (int i = 0; i < sheet.getRows(); i++)
{
Cell cell = sheet.getCell(j, i);
data[j][i] = cell.getContents();
// System.out.println(cell.getContents());
}
}
for (int j = 0; j < data.length; j++)
{
for (int i = 0; i <data[j].length; i++)
{
System.out.println(data[j][i]);
}
}
}
catch (BiffException e)
{
e.printStackTrace();
}
return data;
}
public static void main(String[] args) throws IOException
{
JavaApplication4 test = new JavaApplication4();
test.setInputFile("C://users/admin/Desktop/Content.xls");
test.read();
}
}
Here is my excel sheet,
From a bowl of chits numbered /#v1#/ to /#v2#/ , a single chit is randomly drawn. Find the probability that the chit drawn is a number that is a multiple of /#v3#/ or /# v4#/?
I need to read this data and by matching the pattern /#v1#1, I need to declare the variables. How can I do this?

What you can do, you should first get all the columns from the sheet by using sheet.getColumns() and store all columns in a list . Then you can match get all values based on columns. or you can get for only column "C".try using below code. let me know if this works.
int masterSheetColumnIndex = sheet.getColumns();
List<String> ExpectedColumns = new ArrayList<String>();
for (int x = 0; x < masterSheetColumnIndex; x++) {
Cell celll = sheet.getCell(x, 0);
String d = celll.getContents();
ExpectedColumns.add(d);
}
LinkedHashMap<String, List<String>> columnDataValues = new LinkedHashMap<String, List<String>>();
List<String> column1 = new ArrayList<String>();
// read values from driver sheet for each column
for (int j = 0; j < masterSheetColumnIndex; j++) {
column1 = new ArrayList<String>();
for (int i = 1; i < sheet.getRows(); i++) {
Cell cell = sheet.getCell(j, i);
column1.add(cell.getContents());
}
columnDataValues.put(ExpectedColumns.get(j), column1);
}

This is the very simple and efficient code and Working as expected

but my problem is that it won't work properly if there is an line break in a cell, which is important for me.
I need it to be exactly like when you "save as csv" in Excel.
