Java's graphical interface is still a cross-platform

AWT: Abstract window Toolbox, which consists of three parts:

① components: interface elements;

② container: A container for loading components (such as a form);

③ Layout Manager: Responsible for determining the placement of components in a container.

The application of the graphical interface is in four steps:

① Select a container:

⑴window: A container with a title (such as frame);

⑵panel: Panel

Add components to the container through Add ().

Java's graphical interface is still cross-platform. However, when a form is called, only one form is generated, no event is processed, and the Close button does not work. Only use CTRL + C to terminate the program at this time.

② setting up a layout manager: With setlayout ();

③ adding components to the container;
