CheckBox menu item Decrypt in JAVA GUI - java

I am working on a project and part of ask for:
add a CheckBox menu item Decrypt which can be checked for decrypt or unchecked for Encrypt. This item should be tied to the toggle button in the GUI. Both should reflect the current status of encrypting/decrypting in the application
which is I not sure how to begin with

well to start with, have you created a gui with a JCheckbox and a JToggleButton? If so start by getting your gui created, i'm assuming you are using swing??
Then add an action listener to the checkbox and the togglebutton. You can find a tutorial on action listeners here. Then in the action listener you can check the state of the checkbox and togglebutton and adjust as necessary.
Give this a shot, and post here if you run into problems.

Confusion about RadioGroup handling

I'm currently learning Android development from a book and I've come to the topic of radio buttons. The book explains that you handle radio button clicks (within a RadioGroup) using setOnCheckedChangeListener() with an anonymous OnCheckedChangeListener class as an argument.
However, according to the Android documentation you can set the onClick attribute on radio buttons to simply refer to a method of your design and handle clicks there.
Is there a reason to choose one over the other? What I'm asking is if there is some difference between the two that I'm missing, or if they simply both do the same thing.
setOnCheckedChangeListener() is listening to checked state, so if it is changed programmatically your code will be triggered. onClick listener only detects changes on checked state only if the element is clicked.

Java Swing realtime change componente

Is there a possibility using Java Swing to add in a existing running Swing application a button as an example. The action of the button to have a call to an existing method in that application. Maybe using xml to define the structure of the button.
You can do it. When any action triggered you can create the button and set the listener for it.
But best practice is to create the button and listener at the build time. Here you need to hide/set visibility to false initially and when any action triggered, set the visibility to true.

How to wire action to a button in ControlsFX?

In Swing it was possible to connect action to a button and button was reflecting action's parameters like icon, enableness, text and so on.
Is this also possible with ControlsFX' Action?
If yes then how?
For an existing button you can use ActionUtils.configureButton(action, button).
To create a button bound to the action, use ActionUtils.createButton(action)
