Change Form component from other class

To change a component on a form from another class, for example if we have a GUI which is the startup component and we have a slave class that does a lot of work, calculations, searching and such and we wish to update a coomponent on our form from within this slave class.

In the form class, which we’ll call GUI

slave s = new slave(this);// slave is the other class and “this” is a reference to itself, the GUI

In the other class, which we’ll call slave

GUI form; // where GUI is the name of the form class

    public slave(GUI formObject)//formObject is a reference to the GUI form passed by “this”.

    {

        form = formObject;

        //form.setVisible(true); // not needed as it’s already visible

    }

void changeButton()

    {

        form.setButtonText("hello"); // The setButtonText method is an accessible method in the GUI form

    }

GitHub - Pushing to remote is rejected as a result of email address being exposed

Problem with PyCharm & Clion and gitHub on Mac specifically…

Also found on Debian, probably affects all applications pushing to GitHub

Pushing to remote is rejected as a result of email address being exposed.

Check;

If this shows email address, change is as per below;

git config --global user.email “plisken1@users.noreply.github.com”

Java Collections

Pre condition, post condition and Invariants

1. Pre-conditions are the things that must be true before a method is called.The method tells clients "this is what I expect from you".
2. Post-conditions are the things that must be true after the method is complete. The method tells clients "this is what I promise to do for you".
3. Invariants are the things that are always true and won't change. The method tells clients "if this was true before you called me, I promise it'll still be true when I'm done".
