Class initialization in the Java inheritance Structure

This is the foundation. The following program analyzes the result first. If the result is correct (the result is output in a white font), you are familiar with java class initialization. If not, review it.

Package nie. test. extend;

/** Sub-constructor initialization process:
* @ Author dotjar
* 1. Parent static domain
* 2. Parent static Block
* 3. substatic domain
* 4. Sub-static Block
* 5. Parent common domain
* 6. Parent common block {}
* 7. Parent Constructor
* 8. subnormal domain
* 9. Sub-common block {}
* 10. Sub-Constructor

}
