java - Sort ArrayList by double values -


i have arraylist double values:

double distance = haversinealgorithm.haversineinkm(lat, lon,                     stop.getstoplat(), stop.getstoplon()); distancelist.add(distance);

i can smallest value in list this: 

int minindex = distancelist.indexof(collections.min(distancelist)); currentlist.get(minindex); //it smallest value element

but have know second smallest value , third smallest value element too. don't know how.

i tried sort list this: 

collections.sort(distancelist);

but it's not working. mean last index of list isn't smallest or highest value.

is here can explain me how can solve ? :)

this code looks good:

int minindex = distancelist.indexof(collections.min(distancelist)); currentlist.get(minindex); //it smallest value element

so since in sorted order, can smallest, 2nd smallest, , 3rd smallert value bying directly calling index.

    currentlist.get(0);     currentlist.get(1);     currentlist.get(2);
