I need to fetch the Test data from the excel by passing the test case id. If i pass the Test case id as \"TC005\" - i need to get all the column values like Lab name, Lab

Thyagu: I am proposing one solution... first you should create a method that find the row having desired first cell value (in your case desired TestCaseID I suppose) and return a RowObject for the same.

public static HSSFRow findRow(String stringToFind){
            //`hswb` is HSSFWorkbook
    HSSFSheet sheet = hswb.getSheetAt(0);
    Iterator <Row> rowItr = sheet.iterator();
    while(rowItr.hasNext()){
        HSSFRow row = (HSSFRow) rowItr.next();
        if(row.getCell(0).toString().equalsIgnoreCase(stringToFind)){
            return row;
        }
    }
  // If no such row found need to handle NullPointerException for that
    return null;
}

Once you have the correct RowObject you can extract any non empty cell value from that or can do whatever you want, like in this case I have just printed the same.

    public static void getAllColumnFromRow(HSSFRow RowObject){
    Iterator<Cell> itr = RowObject.iterator();
    HSSFRow headerRow = RowObject.getSheet().getRow(0);
    String cellValue = "";
    String information = "";
    int headerCellCount = 0;
    //to avoid first column
    itr.next();

    while(itr.hasNext()){
        Cell cell = itr.next();
        Cell headerValue = headerRow.getCell(headerCellCount++);
        switch(cell.getCellType()) {
        case HSSFCell.CELL_TYPE_BOOLEAN:
            cellValue = cell.getBooleanCellValue() +"";
            information = information + " " +headerValue+" - "+cellValue+ "; ";
            break;
        case HSSFCell.CELL_TYPE_NUMERIC:
            cellValue = cell.getNumericCellValue() + "";
            information = information + " " +headerValue+" - "+cellValue+ "; ";
            break;
        case HSSFCell.CELL_TYPE_STRING:
            cellValue = cell.getStringCellValue();
            information = information + " " +headerValue+" - "+cellValue+ "; ";
            break;
        case HSSFCell.CELL_TYPE_BLANK:
            break;
        }
    }
    System.out.println(information);
}

In case if any possibility to get a null cell within the last cell values of any row, you need to use MissingCellPolicy.
