"Reading" the code can't bring you any benefits, just like "reading", if you don't think about it when you read it, you will forget most of it after reading it for three months. What is really needed is to "test" the code, adjust the code by hand, change this and that, and see how the result of changing A to B will change.
Steps to efficiently learn source code:
1. Run the program and observe the performance
2. Run the source code, breakpoint debugging, follow the execution process of the source code from the beginning, pay attention to the function stack
3. Draw class diagrams and flow charts, first record the important classes encountered, and indicate the relationship between each class
4. Record the problem, record the class or content that you don't understand in the form of a problem
5. Write articles and notes, and try to solve the remaining problems one by one
6. Requires continuous repetition
