Thinking in Java3rd solves the problem. Although there is a foundation for C/C ++, there are still many things in disorder. The best way to remember is to practice. For me, swing is actually the most attractive and insightful thing. Like bus lines, people who ride bicycles will not be familiar with it. Let's talk a little about my learning experience and so on. Make the simplest one with only buttons in the text editing boxSwingRight: Import javax.

The Graphics class can be interpreted as a brush. It is a drawing class that Java provides for us. Use it to draw: straight drawLine (int x1, int y1, int x2, int y2) rectangle drawrect (int x, int y, int width, int height) round drawoval (int x, int y , int width,int height) fills the rectangle fillRect (int x,int y, int width, int height) fills the circle filloval (int x,int y, int width, int height) figure Slices drawImage (Image img, int dx1, int d

To place a picture in the graphical interface, you need to use the window splitter JSplitPane (belonging to the container class component) to the interface above the imageicon.

The layout uses the Borderlayoutpackage gui;import java.awt.borderlayout;import javax.swing.jframe;import Javax.swing.jlabel;import Javax.swing.jsplitpane;import javax.swing.jlist;import javax.swing

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
