The Graphics class can be interpreted as a brush. It is a drawing class that Java provides for us.

Swing offers a number of utilities that are used internally within swing components, and the Swingutilities class is one of them. It provides a number of methods involving computing, transformation, access control, layout, etc., which have been widely used in various swing components. Of course, we can also apply it to our own program. Here's a look at one of th

With the gradual development, I found that I did not understand anything, And suddenly lost my sense of superiority. Originally, what programmers want to do with this kind of superiority will only let you go downhill, continue to learn and understand and try again to survive. Let's go back to the basics. Otherwise, we will encounter a lot of problems in the future. There are two methods for my understanding about the response of actionlistener. First, you put it in a new class, implement the act
