Making a hello world app in a Form in Intellij

Question

I'm trying to make a hello world form in Intellij. I've created the form, but the question now is what code to make in main() to make the form run and show up?

PS: all the tutorials around seem to only focus on "how to do forms on intellij" not in "how to actually make it run, then".

Thanks

Answer 1

1. Go to the class with the same name as the form.

2. Press the keyboard shortcut for "Generate". It's Ctrl+N on Mac OS X, Alt+Ins on Windows. Alternatively, from the menu, select menu Code → Generate.

3. Select "Form main()".

Now the main method is written and inserted for you. It will look something like this:

public static void main(String[] args) {     JFrame frame = new JFrame("MyForm");     frame.setContentPane(new MyForm().mainPanel);     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     frame.pack();     frame.setVisible(true); }
