Hi All, I wanted to implement a simple sorting for the JTable (I have cursed sun at least 1,000,000 times for not providing that)
I implemented a simple single level sorting taking help from the TableSorter from the Examples. But there is a small complication.
when there are many rows with same values i just leave the order as it is. But now if i sort it based on column 1 first and then go to column 2 then the order is different and if i go to column 3 first and then to column 2 then t order is different
The abililty to sort a collection while leaving equal items in the same order in which they originally appeared is called stability. A stable sort is one that wouldn't have the problem that you describe. The java.util.Arrays.sort(Object) method is a stable quicksort -- you could use that.
Thanks Ernst, I too have done something similar to what you are telling. But the problem that i am facing i will explain Suppose there are three rows (simplified though)
So you see that after the step 2 of both the variations even though i am sorting the column 2 and it indeed is sorted but yet the rows with the same City will not be having the same order as it depends on which column was selected earlier.
I was wanting to know if that is fine as long as sorting is done correctly on the column 2
