Thanks.

Hello there all,

It's been a while since I have sent the requested information in relation to November Promotion: OCP Java Java Programmer SE 21 Practice Exams.

I am positive the goat ate my email by now, which I've sent on November 22, 2024.

I didn't received any answer.

Please let me know if you need me to send the email again?

Thanks a lot!

Thank you.

So, yeah.

Is memory management evaluated in the certification exam? You know, like knowing the inner working of the different available garbage collectors. I don't think that's the case though.

Thanks!

¡¡¡Welcome, Paul Anilprem!!!

Hello there all,

From time to time I'd like to revisit some topics on Java.

I have the following question related to an experiment I was doing using jshell.

All of the following happened inside a jshell session. Because of course the compiler will reject the code.

jshell> public interface Replacer<T> {   ...>   ...>     void replacer(T data);   ...> } |  created interface Replacer jshell> public class Box implements Replacer<T> {   ...>   ...>     private int data;   ...>   ...>     @Override   ...>     public void replacer(T data) {}   ...> } |  created class Box, however, it cannot be referenced until class T is declared

Even when the `Box` class is being created within the JShell session, I was thinking JShell would reject the class definition. Now I am not sure if I am missing something on how to instantiate a Box object class inside the JShell session.

Thanks, if my question doesn't make any sense please dismiss it.

Hello there all,

Table 10.7 contains some methods on Stream classes that shouldn't include space. e.g. `IntUnary Operator` shall be `IntUnaryOperator`. There are several functions in this table containing spaces.

Thanks!

Hello there all, I am not sure if this was already mentioned.


In the section Declaring static Interface Methods (Located in Chapter 7)

(First example of this method)
The Skip class is not implementing Hop. Therefore, it can't access getJumpHeight().

This is an amazing book.

Chapter 3 - The Switch Expression (Section).

Figure 3.4 (The structure of a switch expression). Is missing a required semicolon at the end of the Switch Expression.

Again, if the image isn't displaying inline (I am starting to think this has to do with the internal image viewer on Google Drive instead of being a link directly to an image).

Thanks.

Hello there,

There is a missing colon in Figure 3.3 (Chapter 3, Applying switch Statements - section). Here's an image depicting this report.
