java - Linked list looping and addfirst -

why not working? looping on trxfifoarray list , passing object items result list. need split amounts in 2 need addfirst 2 amount result list. amounts in arraylist [-9.0000, -6.0000]. loop amount list addfirst on result , items added same amount list has 2 different amount.

    linkedlist<invtqatracer> trxfifoarray = new linkedlist<invtqatracer>();     linkedlist<invtqatracer> result = new linkedlist<invtqatracer>();     invtqatracer trx = new invtqatracer();      int trxdocoref = 0;     (int j = list.size() - 1; j >= 0; j--) {         trx = list.get(j);         system.out.printf("%12.4f %4s%10d  %12s%n", trx.gettrxqty(), trx.getdoctype(), trx.getordno(), trx.getlocno());         list<bigdecimal> auxamounts = new arraylist<bigdecimal>();          if (trx.getdoctype().compareto("ov") == 0                 || trx.getdoctype().compareto("xv") == 0) {                     //do ...          } else {             bigdecimal auxamount = bigdecimal.zero;             boolean needremove = false;             (invtqatracer tfifo : trxfifoarray) {                 if (trx.getdoctype().compareto("it") == 0) {                              auxamounts.add(tfifo.gettrxqty().negate());                  }              }             if (needremove) {                 iterator<invtqatracer> iterator = trxfifoarray.iterator();                 int count = 0;                 while (iterator.hasnext()) {                     invtqatracer iqt = iterator.next();                     if (iqt.gettrxqty().compareto(bigdecimal.zero) == 0) {                         count++;                         iterator.remove();                     }                 }             }         }          if (!auxamounts.isempty()) {             (bigdecimal asss : auxamounts) {                 system.out.println(asss);                 trx.settrxqty(asss);                 result.addfirst(trx);             }         } else {             result.addfirst(trx);         }         (invtqatracer invtqt : trxfifoarray) {             system.out.printf("%20s%2s%12.4f %10d  %12s%10d%n", "                                               ----------------> ", invtqt.getdoctype(), invtqt.gettrxqty(), invtqt.getordno(), invtqt.getlocno(), invtqt.getdocno());         }     } 

this code add 2 records -6.000000 value printing out both of them. hope understand code. please help!!!

thanks.

thanks help!

am finding problem in code. code needs updated this

if (!auxamounts.isempty()) {             linkedlist<invtqatracer> result = new linkedlist<invtqatracer>();             //updated here             invtqatracer trx = null;             list<bigdecimal> auxamounts = new arraylist<bigdecimal>(); //[-9.000000, -6.000000]             (bigdecimal asss : auxamounts) {                 system.out.println(asss);             //updated here             trx = new invtqatracer();                 trx.settrxqty(asss);                 result.addfirst(trx);             }         } else {             result.addfirst(trx);         } 

one more change identified inside else loop needremove value set false default , below checking whether true in if loop. think 1 can removed.
