I am attempting to add another checkbox to this program but for some reason it will not display when I run the program. Only the check box for the blue pill displays. I have attempted to add a couple things or change the way the program is structured, but nothing I have done so far has helped.

Code Below:

I have put example dataset (df), expected output (df2) and my code so far below. I have a df where some rows in column i2 contain a list - in the json format, which need exploding and reinserting back into the df, from the row in which they were extracted. But the need to be inputted into a different column (i1). i need to extract a unique identifier (the 'id_2' value) from the string and insert that into the id_2 column.

in my code so far i am parsing the json-like data with pd.normalize, and then inserting the original string from the column i1 onto the top of the extracted strings (it should be much more clear if you take a look below) and then reinsert them based on the index. But I have to specify the index, which is not good. I would like it to be less dependent on manual input of indices in case it changes in the future with more of these nested cells or somehow the index changes.

Any suggestions are very welcome, thanks so much

example data

I am pretty new to JAVA. I want to know how I can create a little program where the user can have the start and the end input (2 user inputs). And then count the in between numbers. Like this for example:

• User input 1 = 5; User input 2 = 10; The result should be: 5,6,7,8,9,10.

After some research I got this code but something is wrong, I really appreciate the help!

So I have a painted rectangle that I want to move with the arrow keys that includes diagonal movement, or rather allowance of multiple keys being pressed at the same time (In other words, movement that is similar to player movement in a 2D game). I have attempted to do this with a KeyListener, which was not working. So I decided to move to KeyBindings and I found an example from this website: https://coderanch.com/t/606742/java/key-bindings (Rob Camick's post)

I directly copied the code and it works as intended, except it is moving an icon and not a painted rectangle like I want to do. I have attempted to modify the code so that it would move a painted rectangle, but was only failing. Here is my latest attempt, which is also a minimal reproducible:

The Swing program shows wrong characters instead of German umlauts. This button should be "Schließen", for example: . This occurs for all UI elements as far as I can see.

The code to create the UI is nothing unusual, for example:

Does anyone know how to start the number counter animation when you scroll to a specific parent id like #counter-container?

I'm trying to add a GUI to the predator-prey simulation. It can allow users to choose which simulation(species involved) they want to do, set the simulation field size they want, and show the progress of the simulation and result.

The question is after I generate the field, I can't reset the simulation or run the next step or run the next hundred steps by clicking the buttons I set, not to mention show the progress of the simulation.

Here is the code of my GUI Class:

I am working on a project that involves the need for a custom Line component (so that additional functionality can be included later - i.e., Lines can be removed and moved about), that draws a new Line on a JPanel (i.e., LinePanel) wherever the user presses the mouse (start point) and drags to (end point). The idea is that the user can click and drag to any point on the panel to create a line (I have included a border in the code to display the bounded rectangle - for feedback). The below code works fine when clicking directly on the LinePanel, however if the user clicks over another Line component the start position is altered - this is the part that is driving me crazy (I suspect that the problem is occurring inside the mousePressed() logic. I'm relatively new to Graphics with Java and would really love some feedback. I'm sure that there is a better way to do this.

i have java swing Class that create JButton

it is working but what i need is when i pressed a JButton lets seed that it is number 1 the code in the ActionEvent is to change the Background of the JButton but what i need is if i pressed another JButton the first one i need it to go back to red Color :

Example :
