Thread: Why does this code now work?

I have been following a video tutorial and need some questions answered about some of the things he types youtu.be/VE7ezYCTPe4?t=10m

Starting at 10:00 in the video he mentions that this BorderLayout is not something we need to know about. I am now getting errors with this code and I am wondering EXACTLY what this does and what perimeters I am not meeting.

In the tutorial he names his frame NAME but I chose a name like he mentioned we could. Here is my code and I get a red line under BorderLayout (I marker this in bold)

frame = new JFrame("D&A");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);
frame.setLayout(new BorderLayout());

frame.add(this.BorderLayout.CENTER);
frame.pack();

frame.setResizable(false);
frame.setLocationRelativeTo(null);;
frame.setVisible(true);


Can anyone help? I have tried Ctrl + Shift + O and imported everything I have been told to.

Sorry for formatting issues I'm new to this Forum and Java in general but do you have a possible solution to my problem I would be very greatful
