The benefits of using Chinese as variable names and function names in Java:
1. Chinese is easy to understand and can greatly improve code readability.
2. Lowering the English threshold will help popularize programming.
3. For long variable names, English is either very long or abbreviated. This type of variable name is more concise in Chinese.
4. English naming actually involves a translation process from Chinese to English and then to Chinese. The two translations will cause understanding errors, resulting in poor code readability.
Disadvantages:
1. The source code cannot be internationalized. If it is open source or foreign colleagues want to study it, it will be difficult to understand.
2. For consoles that do not support Chinese and use reflection software, garbled characters will appear.
3. Before the emergence of IDEs that fully supported Chinese development, switching input methods was quite troublesome.
