I'm going to write a tutorial on a series of Java graphical interfaces. Each program tries to write only the most streamlined code needed to keep it running, so everyone can understand it.Using the Java graphical interface requires only jdk,eclipse. If the layout abstraction is not powerful enough, it is recommended to install Jigloo First and then copy the code. (Jigloo automatically generated code redunda

Each time you write a graphical program, only manually adjust the JFrame frame size to display the contents. Using validate () does not work, and pack () can solve this problem.Pack ()//is automatically adapted to size. When writing a program, if preferred size is defined, the frame size is drawn according to the preferred size, or the component within the container is sized to fit.Vailate ()//is resized, provided the size has been set (SetSize () has
