          objLanguageDetails.languageName=result.getString("languageName");
          objLanguageDetails.languageNo=result.getString("languageNo");
          catch(Exception e)
          System.out.println("Cant Get Details");

     LanguageDetails getAllDetails()
          int i=0;
          LanguageDetails vArray[]=null;
          LanguageDetails objLanguageDetails=null;
          try
          Statement st=con.createStatement();
          ResultSet result=st.executeQuery("Select * From LanguageMast;");
          while(result.next())
          objLanguageDetails=new LanguageDetails();          
          objLanguageDetails.languageName=result.getString("languageName");
          objLanguageDetails.languageNo=result.getString("languageNo");
          vArray=objLanguageDetails;
          i++;          
          objLanguageDetails=null;
          catch(Exception e){
          System.out.println("Cant Get All the Details");
          return objLanguageDetails;
     boolean saveDetails(Vector X)
          LanguageDetails objLanguageDetails=null;
          Vector objVector=null;
          objVector=X;     
          String vlanguageName;
          String vlanguageNo;
          try
               objLanguageDetails=new LanguageDetails();
               objLanguageDetails=(LanguageDetails)objVector.elementAt(0);
               vlanguageName=objLanguageDetails.languageName;
               vlanguageNo=objLanguageDetails.languageNo;
               Statement st=con.createStatement();          
ResultSet rls=st.executeQuery("SELECT * FROM LanguageMast WHERE languageNo='"+vlanguageNo +"'");
               if (rls.getRow()==0)
               rls.moveToInsertRow();
               rls.updateString(vlanguageName,"languageName");
               rls.updateString(vlanguageNo,"languageNo");
               rls.insertRow();
               else
               rls.updateString(vlanguageName,"languageName");
               rls.updateRow();     
               return false;               
          catch(Exception e)
          System.out.println("Cant SAVE the Details");

Do you want to print the stack trace of the exception being thrown?
Use: Throwable.printStackTrace()
