Learning opinions:

1. Watch "Thinking In Java", don't stop watching it just because it is difficult and we are beginners ourselves;

2. Don’t let go of any seemingly simple small programming problems - they are often not that simple, or they can lead to a lot of knowledge points;

3. Talk about fashionable technologies , it is better to keep the outdated technology in mind;

4. One of the best ways to learn programming is to read the source code;

5. Do not think that the book in your hand is at any time It's enough;

6. If you can understand the book, please read it carefully; if you can't understand the book, please read it bravely;

7. Don't expect to read the book for the first time. What can be remembered and mastered - please read the second and third times;

8. Don’t stay in the cradle of the integrated development environment, learn to control the integrated development environment, and learn to use the command line Processing programs;
