how to read .xlsx file in java?

from the given .xlsx file, I am trying to read data using Java programming

My code for read the file is as given below:

public static void main(String[] args) throws Exception {

        FileInputStream file = new FileInputStream(new File("E:\test1.xlsx"));
        XSSFWorkbook workbook = new XSSFWorkbook(file);
        XSSFSheet test = workbook.getSheetAt(0);

        student emp = new student();
        Iterator<Row> itr = test.iterator();
        itr.next();
        while(itr.hasNext()){
               Row row = itr.next();
               emp.reedData(row);
               System.out.println(id+","+name+","+options);

        }

method is as given below:

void reedData(Row row){
         id= row.getCell(0).toString();
         name= row.getCell(1).toString();
         options= row.getCell(2).toString();
         }

But, I am getting output like this:

1.0,X,play game
,,sing song
2.0,Y,play game
,,sing song

Instead of this, I want output like this:

1.0,X,play game
1.0,X,sing song
2.0,Y,play game
2.0,Y,sing song

This problem is because I am combining two cells in .xlsx file.

Any suggestion? Thanks in advance.
