java - Inserting date from JDateChooser to Oracle DB -

-

i having trouble inserting date jdatechooser oracle db. below action event in class staffdisplay. 

`public void savebuttonpressed(actionevent e){          try{             int result = staff.addstaff(                     firstnametextfield.gettext(),                     lastnametextfield.gettext(),                     dateofbirthdatechooser.getdate(),                     departmenttextfield.gettext(),                     double.parsedouble(salarytextfield.gettext()),                     startdatedatechooser.getdate(),                     boolean.parseboolean(fulltimetextfield.gettext()));              if(result == 1){//it worked                 joptionpane.showmessagedialog(this,"staff member added successfully");             }else{//didn't work                 joptionpane.showmessagedialog(this, "error occured - staff member not added");             }`

this prepared statement in different class.

 `public class staffqueries { private static final string url = "jdbc:oracle:thin:@localhost:1521:xe"; private static final string username = "xxx"; private static final string password = "xxx";  private connection con;  private preparedstatement insert = null;   public staffqueries() {      try{         class.forname("oracle.jdbc.driver.oracledriver");         con = drivermanager.getconnection(url,username,password);         system.out.println("drivers loaded , connection made");          insert = con.preparestatement("insert staff " + "(staffid, firstname, lastname, dateofbirth, department, salary, startdate, fulltime)"                 + "values(colmstaffsequence.nextval,?,?,?,?,?,?,?)");      }catch(sqlexception e){         system.out.println("something went wrong database");         e.printstacktrace();         system.exit(1);      }catch(exception e){         system.out.println("something went wrong when loading drivers");         e.printstacktrace();         system.exit(2);      } }   public int addstaff(string fn, string ln, date dob, string d, double sal, date sd, boolean ft){          int results = 0;          try{             //fill in missing parameters prepared insert statement             insert.setstring(1, fn);             insert.setstring(2, ln);             insert.setdate(3, dob);             insert.setstring(4, d);             insert.setdouble(5, sal);             insert.setdate(6, sd);             insert.setboolean(7, ft);              //execute prepared insert statement             results = insert.executeupdate();         } catch (sqlexception e){             e.printstacktrace();             close();         }         return results;     }`

there error message says 

   `exception in thread "awt-eventqueue-0" java.lang.error: unresolved compilation problem:  method addstaff(java.lang.string, java.lang.string, java.sql.date, java.lang.string, double, java.sql.date, boolean) in type staffqueries not applicable arguments (java.lang.string, java.lang.string, java.util.date, java.lang.string, double, java.util.date, boolean)`

so think date insertedd jdatechooser entered java.util.date , need java.sql.date? if problem? if how convert java.sql.date? thanks.

you can use new java.sql.date(long milis) , getting milliseconds selected date using startdatedatechooser.getdate().gettime()

Android volley - avoid multiple requests of the same kind to the server? -

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
