1 Method 1.1 Method Overview

• Suppose there is a game program in which the program is constantly firing shells (plants vs. Zombies) during operation. Firing shells requires 100 lines of code to be written, and each time a projectile is implemented, the 100 lines of code need to be written repeatedly, so the program becomes bloated and poorly readable. In order to solve the problem of code duplication, you can extract the code of the firing shells into a {}, and give the code a name, so that the name of each firing cannon to invoke the code of the firing shells.
• In the above procedure, the extracted code can be considered as a method (or function) defined in the program, and the program can call the method directly when it needs to fire the shells.
