Example
Java
// Java Program to Demonstrate Creation Of Cell// At Specific Position in Excel File// Importing required classesimport java.io.*;import org.apache.poi.hssf.usermodel.HSSFWorkbook;import org.apache.poi.ss.usermodel.Cell;import org.apache.poi.ss.usermodel.Row;import org.apache.poi.ss.usermodel.Sheet;import org.apache.poi.ss.usermodel.Workbook;// Class// CreateCellAtSpecificPositionpublic class GFG { // Main driver method public static void main(String[] args) throws FileNotFoundException, IOException { // Creating a workbook instances Workbook wb = new HSSFWorkbook(); // Creating output file OutputStream os = new FileOutputStream("Geeks.xlsx"); // Creating a sheet using predefined class // provided by Apache POI Sheet sheet = wb.createSheet("Company Preparation"); // Creating a row at specific position // using predefined class provided by Apache POI // Specific row number Row row = sheet.createRow(1); // Specific cell number Cell cell = row.createCell(1); // putting value at specific position cell.setCellValue("Geeks"); // Finding index value of row and column of given // cell int rowIndex = cell.getRowIndex(); int columnIndex = cell.getColumnIndex(); // Writing the content to Workbook wb.write(os); // Printing the row and column index of cell created System.out.println("Given cell is created at " + "(" + rowIndex + "," + columnIndex + ")"); }} |
Output: On console
Given cell is created at (1,1)
Output: Inside file named ‘Geeks.xlsx’
