          Calendar calendar = Calendar.getInstance();
          int month = calendar.get(Calendar.MONTH);
          calendar.set(Calendar.MONTH, month-1);
          calendar.set(Calendar.DATE, calendar.getActualMaximum(Calendar.DATE));
          System.out.println("Previous Month End Date is :: " + simpleDate.format(calendar.getTime()));From the above code i am able to find the last month end date according to System date .

Thanks all,
Hope this is the solution .
Any Suggestions will be appreciated
String dateString = "10/2009";
         StringTokenizer st = new StringTokenizer(dateString,"/");
         String dateStringm = (String) st.nextElement();
         int month = Integer.parseInt(dateStringm);
         String yearStringm = (String) st.nextElement();
         int year = Integer.parseInt(yearStringm);
         System.out.println("month :"+month);
         System.out.println("year :"+year);
         Calendar calendar = Calendar.getInstance();
         calendar.set(year, month,1);
         calendar.set(Calendar.MONTH, month-1);
         SimpleDateFormat dateFormat = new SimpleDateFormat("MM/yyyy");
         String previous_month_end_date =  dateFormat.format(calendar.getTime());
          System.out.println("Previous Month End Date is :: " + previous_month_end_date);
          Calendar cld = Calendar.getInstance();
          cld.set(Calendar.DAY_OF_YEAR,1);
          String year_start_date =  dateFormat.format(cld.getTime());
          System.out.println("First day of year is :: " +year_start_date);
