Learn Java from Scratch - A Beginner's Guide - Step 04 - Comparing Prototype Versus Singleton - Spring Framework Bean Sc

The video tutorial explains the differences between prototype and Singleton bean scopes in Spring. Prototype beans create a new instance each time they are requested, while Singleton beans reuse the same instance. Singleton is the default scope if none is specified. Prototype beans are rarely used, with most Spring beans being singletons. Prototype beans are suitable for stateful applications, while Singleton beans are ideal for stateless applications. The tutorial also covers how to specify bean scopes using annotations.

What is the main difference between prototype and singleton bean scopes in Spring?

• Prototype beans are created once per application.

• Singleton beans are created once per user session.

• Prototype beans are created every time they are requested.

• Singleton beans are created every time they are requested.

What happens if no scope is specified for a bean in Spring?

• The bean defaults to request scope.

• The bean defaults to prototype scope.

• The bean defaults to singleton scope.

• The bean cannot be used without a specified scope.

How often are prototype beans used compared to singleton beans?

• Prototype beans are never used.

• Both are used equally.

• Singleton beans are used more frequently.

• Prototype beans are used more frequently.

In which scenario would you use a prototype bean?

• When you need a stateless bean.

• When you need a stateful bean for each user.

• When you need a bean shared across the application.

• When you need a bean for a single request.

What type of bean should be used for generic operations across an application?

• Prototype bean

• Singleton bean

• Request bean

• Session bean
