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

can't you use a Set instead of List? for example look at HashSet — peshkira

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.

but ı shouldnt change my real value because this code will be 1500 double value after that

David Over a year ago

@user2583040, It doesn't change the real value - TreeSet simultaneously sorts and de-duplicates, which is exactly what you asked for. If you want the values back in an ArrayList after that's done, just call new ArrayList(treeSetInstance);

npinti Over a year ago

@user2583040: Just as @David suggested, all you need to do is to iterate over your current list and put your values in the TreeSet. The set will automatically sort and remove any duplicates you might have in your data.

user2583040 Over a year ago

@npinti do you have any example about it? because ı never ever hear treeset :(

npinti Over a year ago

@user2583040: YOu can check here: tutorialspoint.com/java/java_treeset_class.htm This is a very basic example but it should cover what you need. You can alternatively provide a comparer so that you can chose the way that the objects are sorted. I'd recommend you check the Javadoc (linked in my answer) for more information.

my pleasure buddy, so did you got your answer? does it work good? I hope there is no any problem/issue? Hallelujah :)
dude =) you put n kolons but if you look my text there is 6 numbers .ı take first numbers like 1.75, 1.43,1.29 1.29. I put them on one array, 2. numbers to other array, ı have 6 array because ı have 6 point near all of sencentence.Then ı sort them.. now you take n kolons. But ı have to be take 6 kolons because ı take 6 point only. ı try aplied my code but ı cant it. so sory dude :( ı take your time .. very very thanks..
this code works as you exactly want, it contains one list for each row, and your text file contains 8 line which each line has 6 points, I also add all of the numbers into numbers list, and rows contains list of each row value, in for loop it checks the duplication then insert, but it is easy for columns too, I will add it for columns too buddy :)
I updated the answer, check the second, one, may you need this, I hope :))
its work very goood :D you are best of the coder in the world in my mind.. thank you so much dude =)))) so much thank you...
