Learn Java from Scratch - A Beginner's Guide - Step 09 - Building REST API to Update a Course – PUT

This video tutorial explains how to update a course using PUT mapping. It begins with an introduction to the concept, followed by a detailed implementation of the PUT mapping method. The tutorial then demonstrates executing a PUT request to update course details and discusses improvements by adding path variables. Finally, it verifies the success of the update process, ensuring the course details are correctly modified.

What is the main similarity between the POST and PUT methods when updating a course?

• Both require a path variable.

• Both methods are used for deleting resources.

• Both use the same request body.

• Both require a unique URI.

What is the purpose of using a path variable in a PUT request?

• To determine the request method.

• To define the type of request.

• To specify the server address.

• To identify the specific resource being updated.

Why is it important to include an ID in the URI when updating a resource?

• To uniquely identify the resource being updated.

• To specify the type of data being sent.

• To ensure the request is sent to the correct server.

• To indicate the request method being used.

What issue might arise after executing a PUT request if the server restarts?

• The URI might change.

• The server might crash.

• The update might not be saved.

• The request might be sent twice.

How can you verify that a PUT request was successful?

• By sending another PUT request.

• By checking the server logs.

• By refreshing the resource list.

• By restarting the server.
