使用Collections给集合排序

  Collections.sort(ydShips, new Comparator<YdShip>() {
                @Override
                public int compare(YdShip o1, YdShip o2) {
                    if(o1.getNumber()> o2.getNumber()){  //number是用来排序的列
                       
             return 1;
                        
            }else if(o1.getNumber()==o2.getNumber()){
                        
            return 0;
                        
            }
                   
             return -1;
                
        }
            });
