kolon1:1.75,1.43,1.29...
kolon2:1.25,1.14,1.10..
then ı sorted them smallest to bigger.
there are replaced number ı dont want replaced number. for exemaple if my contain text contain 3,3,3,3,3,2,2,2,2,1,1,1,1,1,1
ı want only 1 2 3

Take a look at TreeSet :
A NavigableSet implementation based on a TreeMap. The elements are ordered using their natural ordering, or by a Comparator provided at set creation time, depending on which constructor is used.
This should make sure that you have only one of each element and that the list is sorted according to what you need.

try this, it finds duplicate values in all rows, and each row too, works for me :)
