How to save Java objects into a database?

Typically, when storing Java objects in a database, it is common to use Object-Relational Mapping (ORM) tools such as Hibernate, MyBatis, etc. Below are the general steps:

1. To create a database table, you first need to create a table in the database with fields that correspond to the properties of the Java object.
2. Create Java objects: Develop a Java class with attributes that correspond to the fields in a database table.
3. Configuring mapping relationships using an ORM tool: Configuring the mapping relationship between Java objects and database tables using an ORM tool to store Java objects in a database.
4. Instantiate a Java object: Create an instance of a Java object and set its attributes.
5. Invoke the save method of the ORM tool: save Java objects to the database using the save method of the ORM tool.
6. Check if the database has successfully stored the Java object: Finally, you can verify if the database has successfully stored the Java object.

It is important to note that when using an ORM tool, one should refer to the specific ORM framework’s documentation and examples to ensure that Java objects are correctly stored in the database.
