Please guide: I want to use payload variable created in excelutility class to another java executable class

Question

Trying to use payload variable extracted from an excel sheet in another executable class where I want to post the payload on MQ, although not able to access the variable. How can I use this variable to other class.

  package datasource;
 
    import org.apache.poi.xssf.usermodel.XSSFCell;
    import org.apache.poi.xssf.usermodel.XSSFRow;
    import org.apache.poi.xssf.usermodel.XSSFSheet;
    import org.apache.poi.xssf.usermodel.XSSFWorkbook;
    
    import java.io.FileInputStream;
    import java.io.IOException;
    
    public class excelUtility {
    
        public static void main(String[] args) throws IOException {
    
            String excelfilePath= "src/main/resources/Book1.xlsx";
    
            FileInputStream inputStream= new FileInputStream(excelfilePath);
    
            XSSFWorkbook workbook=new XSSFWorkbook(inputStream);
            XSSFSheet sheet= workbook.getSheet("sheet1");
    
            int rows= sheet.getLastRowNum();
            int cols= sheet.getRow(1).getLastCellNum();
    
            for (int r=0; r<=rows; r++){
    
                XSSFRow row= sheet.getRow(r);
    
                for(int c=0; c<cols; c++){
    
                    XSSFCell cell= row.getCell(1);
                    String payload= cell.getStringCellValue();
                    System.out.println(payload);
                   
    
                }
            }
    
    
        }
    }
