My name is Nnamdi. I am a new member in this forum. I am learning Java programming and how to develop Java GUI application. In my learning process, I have encountered the challenge stated below.
My question:
I am writing an application to properly align the GUI component exactly the way it appears in the attached file here but my application is not displaying the GUI exactly the way it is. Please I will be glad if someone can go through the code i have written for this which is shown here and correct me where I did not get it right. You can run my code to see exactly how my own code displays. I want it to be properly aligned to display exactly like the attached picture below. I will welcome hearing from members soonest.
Thank you.
