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
