Sorting with 2 parameters

Hi all

I am looking to sort an ArrayList with a comparator. I first ordered by hitChi which is from the .getHitChi method. However, hitChi is not unique and duplicates are present. I cannot eliminate these duplicates since they contain other important data.

So is this the correct way to sort using a second parameter, a unique code called hitID or am I likely to get some weird results ?

By the way, I can't sort by HitID the first time around since hitChi is meaningful!

Cheers

Colin

Collections.sort(hitsList,new Comparator<Hit>(){

publicint compare(Hit hit1, Hit hit2){

if (hit2.getHitChi() - hit1.getHitChi() !=0 ){

return hit2.getHitChi() - hit1.getHitChi();

}

else{

return hit2.getHitID() - hit1.getHitID();

}

}

});
