worktime | 定位为项目管理，BUG管理。特点是容易安装，使用方便，界面简单友好。

I'm having an issue with some pointers from what I can read about java. It always passes parameters as values rather than references. here

I have a project and employee class that should "share" an object but when I create an instance of activity, add it to the project list and then later add it to the employee list of activities it works. But then when I change the worktime for an employee it's only visible via the project instance where i add the worktime from. It's not visible when i then call the activity worktime from the employee object. Is there a way to "share" an object between classes e.g. pass it by reference like you can in PHP?

When I output the hashcodes of the activity objects in both classes they are also different...

Project class:

I am making a db in Sqlite on android studio.

this is my code:

I've tried making a Google Apps Script, but I was having trouble trying to understand how to set it up. From this it seems like I can create a function that I can call inside the spreadsheet itself like the SUM function provided by Google Sheets. I've taken a look at the getBackground() function, but it seems like it needs some global variables included instead of just functions.

Here's my current spreadsheet:

I want to input a function where it takes in the ranges A2:A1000 and based on the background color of the cell, determine whether it goes into "Work" or "Life" and then adds it onto the cells E4 (Total Work) or F4 (Total Life) accordingly. The cells in column A will always be numbers.

Here's what I've tried, I think I may be off the path completely based off of my single cell approach:

hello I am currently learning about streams in flutter and I came across a timer application. that involves me storing data using shared preferences. I have a thrown exception when I try to store the default preference to the phone I traced it back to this code block:

Target is to sum and annotate workingtimes for each employee on a given time range.

I want to get data from API, my API data as DoctorModel inside it daysModel, inside daysModel is workTimeModel, each doctor has many days and has worktime.

I tried a lot of ways but still can't fix it.

note: I made my API from this website https://app.quicktype.io/

my code to get API data:

I have made relational database model using MagicDraw tool. Every cashier has their workTime type saved in enumerator:

Then I generate DDL code and try to paste it into phpMyAdmin to generate DB but I get many errors. I tried to fix them by hand but errors are still here. So how should that check statement be written?

Errors:

I'm adding a field in a workitem and I want to capture in a separate field the date and time that the filed was changed. I have it working, sort of. When the user changes the dropdown list value to Yes, a field opens below that will be used to record the time the value about changed to Yes. When the user saves the worktime, the system adds the time of the save to that field. I can go back to that work item and I can see the value. But if I update any other information and save the workitem the time stamp is updated again to when the WIT was just saved. My desired workflow is to set the time only when that field is set. I also have a rule that will EMPTY the field if the Value was changed from Yes to No.

Here is the section of the field definitions for the fields in question.
