What are containers and components in React?

Which is a Container of classes in Java?
Class Container. A generic Abstract Window Toolkit(AWT) container object is a component that can contain other AWT components. Components added to a container are tracked in a list. The order of the list will define the components’ front-to-back stacking order within the container.
What are the subclasses of Container class?
A Container is a subclass of Component that can contain other components, including other containers. Container allows you to create groupings of objects on the screen. This chapter covers the methods in the Container class and its subclasses: Panel, Window, Frame, Dialog, and FileDialog.
Why we use containers in React?
The purpose of the container is to map the state and dispatch to props for the presentational component. React, Redux are independent libraries. React provides you with a framework for creating HTML documents. Components are in a way representing a particular part of the document.
What do containers do?

What is a container class Java?
Container is an abstract class that serves as a general purpose holder of other Component objects. The Container class holds the methods for grouping the components together, laying out the components inside it, and dealing with events occurring within it.
What are pure components?
Pure Components in React are the components which do not re-renders when the value of state and props has been updated with the same values. If the value of the previous state or props and the new state or props is the same, the component is not re-rendered.
What is an example of component?

A hardware component can be a device as small as a transistor or as large as a disk drive as long as it is part of a larger system.
What is the difference between component class and container class in Java?
The class Component is the abstract base class for the non-menu user-interface controls of AWT. A component represents an object with graphical representation. The class Container is the superclass for the containers of AWT. The container object can contain other AWT components.
What’s the difference between container and presentational components?
Container components are mostly concerned with the “backend” operations. They might handle the state of various sub-components. They might wrap several presentational components. They might interface with Redux.
What’s the difference between a component and a container in react?
Component is part of the React API. A Component is a class or function that describes part of a React UI. Container is an informal term for a React component that is connect -ed to a redux store.
