java if statement text prompt not working

Very new to coding and not one of my strengths in the slightest... Initially my text prompt would work saying that you need to "enter a name" but for some reason now it doesn't is there another way of writing this code?

Also would anyone be able to point me in the direction of how to do a JPanel with a JTextArea that When a button is pressed, the text area will display "name" is hungry ? I have had a look around various things but cant get my head around it. Thanks
