💡 Hint

Common Mistakes

Using lowercase 'content-type' which may cause confusion.

Using unrelated headers like Accept or Authorization.

HTTP headers are case-insensitive but conventionally use 'Content-Type' with capital letters.

4fill in blank

hard

Fill both blanks to create a ResponseEntity with status 201 CREATED and a Location header.

Spring Boot

return ResponseEntity.status(HttpStatus.[1]).header("[2]", "/items/123").build();

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using ok() instead of CREATED.

Using content-type header instead of Location.

The ResponseEntity.status(HttpStatus.CREATED) sets status 201, and the Location header tells where the new resource is.

5fill in blank

hard

Fill all three blanks to return a ResponseEntity with status 204 NO CONTENT, a custom header, and no body.

Spring Boot

return ResponseEntity.[1]().header("[2]", "no-cache").[3]();

Drag options to blanks, or click blank then click option'

AnoContent

BCache-Control

Cbuild

Dbody

Attempts:

💡 Hint

Common Mistakes

Using body() which requires a body for 204 status.

Using wrong header names.

noContent() sets HTTP 204 status, Cache-Control is a header for caching, and build() completes the response without a body.
