What classes can you name for configuring a container?

To configure a container in Java applications, especially in the context of the Spring Framework, the following classes can be named:

• ApplicationContext — the main container interface that loads configuration and manages the lifecycle of beans.
• AnnotationConfigApplicationContext — a container configured using Java annotations.
• ClassPathXmlApplicationContext — a container that loads configuration from XML files in the classpath.
• GenericApplicationContext — a versatile container that can be configured programmatically.

In Java EE:

• ServletContext — a container for web components.
• EJB container — manages the lifecycle of Enterprise Java Beans.

Example of creating a Spring container with Java configuration:

AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(AppConfig.class);
MyBean bean = context.getBean(MyBean.class);
context.close();
