In Excel handling how is it that we call getRow without creating object of XSSFSheet class

Question

How is it that we invoke getRow() and getCell() without creating object of XSSFSheet class. To create an object we use new keyword right but without using new keyword how is it that we can call the non static methods getRow() and getCell ()

Ex:
XSSFWorkbook workbook = new XSSFWorkbook(fs);
XSSFSheet sheet = workbook.getSheetAt(0);
Row row = sheet.getRow(0);
Cell cell = row.getCell(0);

As we can see here we are calling getRow() and getCell() without creating object of XSSFSheet class using new keyword.

Answer 1

There is a concept of method chaining where we get the reference of a class or an interface and with that reference, we can call the methods.
