如何使用API读取google电子表格中的工作表？

Question

我有一个谷歌电子表格，其中包含2-3个独立的工作表。我正在寻找一种方法来查看工作表# 2中包含的行，然后循环遍历前面找到的每一行的列。

要做到这一点，我需要使用哪种API方法？我在google spreedsheet API页面上找不到这个。

        // Load sheet
        URL metafeedUrl = new URL(SPREADSHEET_URL);
        SpreadsheetEntry spreadsheet = service.getEntry(metafeedUrl,SpreadsheetEntry.class);
        URL listFeedUrl = spreadsheet.getWorksheets().get(0).getListFeedUrl();

        // Print entries
        ListFeed feed = service.getFeed(listFeedUrl, ListFeed.class);

            }
        }

    }catch(Exception e){
        System.out.println(e);
