Problem with creating program flow in java database application

I have created hardware shop database in SQL. Database needs to be connect to java, everything is done so far even the screen designs. However, there is problem I can’t picture/design how to application should work as program flow. There is login for employess, and employees use this application in their shop. When customer comes in and what to buy something. I realize that is very vague and weird question but how could do this?

Mailchimp Facebook integration not saving “Page to Use”

I have setup the Facebook integration in mailchimp. I successfully connected to Facebook and accepted all permissions. After connecting, under “Add a signup form to your Facebook Pages and auto-post campaigns,” I selected the page to use and the list to use. I added the signup tab/page and click “Save.”

The tab/page is created under the selected business page but when I return to the integrations page in Mailchimp the “page to use” shows a different page (the first one in the dropdown list). Is this how it’s supposed work?

Just concerned that the “Post to Facebook” option under a campaign will post to the wrong page. I can’t see a way to check which Facebook page the campaign will post to.

Many Thanks!

returning error string or null for “no errors”

In my code I have several validation methods which have common part. I extracted common part into dedicated method and now code looks like this:

public String validate1() {   String common = validateCommon();   if (common != null) {     return common;   }   // do something   return something1; }  public String validate2() {   String common = validateCommon();   if (common != null) {     return common;   }   // do something   return something2; }   public String validateCommon() {   ... } 

I don’t like how null has special meaning of “no errors occured`. May be I can refactor to something like this:

public String validate1() {   return validateCommon().orElseGet(() -> {      // do something      return something1;   }); }  public Optional<String> validateCommon() {   ... } 

But this doesn’t look beautiful too, because “normal” code is under orElseGet, but error processing is at the beginning of the method, this looks odd.

Can I refactor it to something more readable?

How to use my .mo file in the child theme instead of file in a parent custom directory?

there is a Lang folder in my parent wordpress theme; I added my own .mo file in the child-theme using load_theme_textdomain. but there is another file located in /includes/builder/languages parent theme directory. how I can add another .mo file to my child to take effect on this part? thanks for your help.

Specified data directory does not exist – but it does…

anyone ever had a similar issue where the directory exists but bitcoin-cli isn’t recognizing it? Perhaps this is related to me setting the folder up as a symlink to my external HDD?

Thank you! aaronson

SharePoint 2013 RestAPI retrieve Task and subtask Parent id undefined

I am trying to retrieve the sub-task of the parent task from a list. query:

../_api/web/lists/getbytitle(‘Tasks’)/items?$ select=Title,Status,ParentID/Id&$ expand=ParentID


function onQuerySucceeded(data) {     var mainTasks = [];     var subTasks = [];     for (var i = 0; i < data.length; i++) {         if (data[i].ParentID.Id) {             subTasks.push(data[i]);         } else {             mainTasks.push(data[i]);         }      }     $  .each(data.d.results, function (key, value) {         subTasks += '<strong>Title: </strong> ' + value.Title +             ' <strong>Status:</strong> ' + value.Status + ' <strong>Parent Id:</strong> ' + value.Id +             '<br />';     });      $  ("#divSubTaskItems").html(subTasks);  }; 

My results are:

undefined: “Title: Test rest Call Status: In Progress Parent Id: undefined”
