使用Java TableRowSorter对长整数排序

Question

I'm have a table that handles large numbers, and I want it to be sorted. The table has no problem displaying the numbers, but TableRowSorter seems to treat the numbers as Integers, thus sorting large values incorrectly when they exceed the maximum Integer value. How can I use TableRowSorter to sort Longs?

Answer 1

but TableRowSorter seems to treat the numbers as Integers, thus sorting large values incorrectly when they exceed the maximum Integer value

Thats because by default data added to a table is treated as a String. You need to override the getColumnClass() method of your TableModel to return the proper Class of the data in the column and the row sorter will use the appropriate Comparator for that type of data.

您可以尝试指定自己的比较器 ，该比较器将提供有关如何比较值的详细信息。

Answer 3

将这些长数字视为字符串，表行排序器将对它们进行正确排序。
