How to get names containing particular Character in Java? - java

I have a workbook in which I have multiple tabs now I want to read all the tabs name and return the tab name containing particular character in it , in my case its data
example assumpition is :-
Expected tabsname - > welcome_data.xslx , hello_value.xslx;
output -> welcome_data.xslx
Any help is appreciated ,
code which I was trying was :- I was able to get the tabs name but how to filter it .
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
public class EXcelsheet {
public static void main(String[] args) throws IOException {
String xlsxFile = "/home/working/git/ui_spec.xlsx";
FileInputStream file = new FileInputStream(new File(xlsxFile));
XSSFWorkbook workbook = new XSSFWorkbook(file);
System.out.println("number of sheet::" + workbook.getNumberOfSheets());
List<String> sheetNames = new ArrayList<String>();
for (int i = 0; i < workbook.getNumberOfSheets(); i++) {
sheetNames.add(workbook.getSheetName(i));
}
}
}

I don't get the issue.
Does replacing
sheetNames.add(workbook.getSheetName(i));
with
String sheetName = workbook.getSheetName(i);
if (sheetName.contains(<char>)
{
sheetNames.add(workbook.getSheetName(i));
}
not work?

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];

fetch image from excel using java

I am working with Apache POI. I am able to read data from excel, but unable to read image from the excel. How to read image from excel.
Instead of puzzling around let's have a complete example.
import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.PictureData;
import java.io.InputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.List;
import java.util.Iterator;
class ReadExcelImages {
public static void main(String[] args) throws Exception{
InputStream inp = new FileInputStream("test.xls");
//InputStream inp = new FileInputStream("test.xlsx");
Workbook workbook = WorkbookFactory.create(inp);
List lst = workbook.getAllPictures();
int i = 1;
for (Iterator it = lst.iterator(); it.hasNext(); ) {
PictureData pict = (PictureData)it.next();
String ext = pict.suggestFileExtension();
byte[] data = pict.getData();
if (ext.equals("png")){
FileOutputStream out = new FileOutputStream("pict" + i++ + ".png");
out.write(data);
out.close();
} else if (ext.equals("jpeg")) {
FileOutputStream out = new FileOutputStream("pict" + i++ + ".jpeg");
out.write(data);
out.close();
}
}
}
}
Works for me with HSSF (*.xls) as well as with XSSF (*.xlsx).

You are using the right imports but you need to have the required jxml jars in your build path also.
you can read here, what is jExcel API here is a tutorial also you can download API from here please download jexcelapi_2_6_12.zip, after downloading extract it and put jxl.jar in your build path, those errors should go then
