What should I do if I want to modify the variable name when writing code?
A lot of codes have been written, and the cvs one by one are very slow, so you can modify them uniformly!
The blogger wants to change flower_class to minst_class
1. Find the location of the variable definition
2. Right click ➡ Refactor ➡ Rename, or shift+F6
3. Tap the new variable name in the red box
4. Enter to confirm
In this way, the batch replacement of variable names is successful!
