Set the path to the file to read data from xlsx?
You need to read the information in the cells.
My code is below:
import java.io.IOException;
import java.io.FileNotFoundException;
import java.io.*;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
public class miniwolfi
{
public static void main(String[] args) throws IOException {
File excel = new File("/tmp/table.xlsx");
FileInputStream fis = new FileInputStream(excel);
XSSFWorkbook wb = new XSSFWorkbook(fis);
double result = wb.getSheetAt(0).getRow(0).getCell(0).getNumericCellValue();
System.out.println(result);
fis.close();
}
}
java.io.FileNotFoundException: /tmp/таблица.xlsx (No such file or directory)
