Filter ArrayList<Object> based on based between two intervals android -

in arraylist, how can 1 filtered arraylist rows between 2 dates.

for example,

find students in arraylist october december 2015.

new student ("12/05/2015",john, level2); new student ("13/05/2015",bisnet, level2); new student ("5/05/2015",tube, level2); new student ("7/05/2015",eros, level2); new student ("4/05/2015",mackay, level2); new student ("8/05/2015",walnet, level2); 

here working. if date between start , ending date. must display true else false

public  boolean systemdate(date startdate, date enddate, string exps) {          simpledateformat sdf = new simpledateformat("yyyy-mm-dd");         date  expenselsdate=null;         try {              expenselsdate   = sdf.parse(exps.substring(0,10));          } catch (parseexception e) {}         //  date expenselsdate = datefortmat(exps);          //simpledateformat dateformat = new simpledateformat("dd-mmm-yyyy");//dd-mmm-yyyy hh:mm:ss aa        // date converteddate = new date();        // arraylist<expenses> filtereddate = new arraylist<>();        // iterator<expenses> iterator = llist.iterator();         /* (expenses temp : llist) {             try {                 converteddate = dateformat.parse(temp.date_of_entry);             } catch (exception e) {                 e.printstacktrace();             }*/             if ((expenselsdate.before(enddate)) && (expenselsdate.after(startdate))) //here "date2" , "date1" must converted dateformat             {                 log.e("valid","true");                 //filtereddate.add(converteddate); // can use these filtered arraylist                 return true;             }         //}         log.e("valid","false");          return false;     } 

the above method used filter baseadapter.
