How to convert MYSQL Query to JPQL Query? Instead of converting is it possible to use same query to update entity in Java swing Program?

mysql query select * from project.newproject; update newproject set pedate = date_add(psdate, interval duration day)

My Entity class is showing below

So I've been developing a small LinkedHashMap extension class for use in one of my projects, where I've edited it to have a value change listener in the put method. Heres my map class:

First question here, hopefully I do this correctly.

Below is a minimal example of my problem that I quickly whipped up representative of my project. I have created a custom renderer for a JList containing some objects (in the example I've used Strings for illustrative purposes). My issue is that, as far as I can tell, if I add a ListSelectionListener to the list, the family of setSelected...() methods do not fire events that trigger the conditional if(e.getValueIsAdjusting()).

In the example below, the problem is immediately obvious upon starting the program: even though list.setSelectedIndex(2); is called after assigning the JLabel's selected text as "none", it does not change until you, the user, click the list items. In fact, it must be a different item to the one currently selected.

I would like this functionality so that the flow of my program will be that, after a user adds/removes items from the list, the "view" is immediately updated once the selected list item is changed.

Have I done something wrong, or am I approaching this incorrectly?

Thank you. :)

I created a User bean class and bind it to a JTextField. I'd like to update the textfield when a method setName of the bean is call. Here is the code:

I am trying to write a text editor. I want two TextAreas: 1st one for typing/editing in unicode script and 2nd one for simultaneously printing output of the unicode script input in corresponding Roman Script (ASCII) set by myself on the basis of a transliteration scheme. I am not able to update and simultaneously print the input text in output textarea while I call the transliteration method. I can sense a little bit that there is something wrong while I set the output textArea to print simultaneously but I am unable to find out what exactly is that.

I am learning Kotlin and writing code to check my understanding. I'm trying to use a toString override to print the values of a hashMap that is a property of a class. I can't get it to work. Instead I get output like "kotlin.Unit() -> kotlin.Unit". Also, I don't understand why the values of the hashMap ARE printing out before the toString output. I don't know where that output is coming from. Please help me. Thanks. Below is my code and the output I'm getting. Code:

I'm trying to learn Kotlin and I'm writing code to test and confirm my understanding. In the result of the following code, I expect to see "Property age changed from 37 to 38" near the end. Why am I not seeing that.

I tried writing the increment to age as age.plus initially, but that made the same result.

I'm developing a new look and feel and now I have a bug with the component JtextField when to use it inside the JTabbledPane component.

So the bug is this
