A DESCRIPTION OF THE PROBLEM :
The synchronous example in HttpClient javadoc (lines 96-107) references
an undefined 'request' variable, which causes a compilation error if
someone copies the example code directly.

File: src/java.net.http/share/classes/java/net/http/HttpClient.java
Lines: 96-107

The asynchronous example (lines 111-119) correctly shows the HttpRequest
creation, but the synchronous example is missing this step.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Open HttpClient javadoc
2. Copy the synchronous example code (lines 96-107)
3. Try to compile it

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The example should compile and run without errors.
The HttpRequest should be declared before being used in client.send().
ACTUAL -
Compilation error: 'request' variable is not defined
