I finished Learn Java, Learn Intermediate Java, and Java for Programmers (though, the latter was mostly just a rehash of what I already knew). Is there anything else on Java I should check out here, on Codecademy? I don’t have a Pro subscription so Learn Advanced Java is not available for me
https://www.codecademy.com/catalog/language/java lists all courses in Java.
Of the free offerings, the only ones not mentioned in your post seem to be:
-
I think the “Code Challenge” section in https://www.codecademy.com/learn/learn-java-loops-and-arrays is available.
-
I think (barring the quizzes), the Java Algorithms course is free: https://www.codecademy.com/learn/java-algorithms

Thank you! Does Codecademy have anything on Java enums? They weren’t covered in either course
I don’t know if enums have been discussed in any of Codecademy’s Java courses. I have seen enums in the TypeScript course, but that material is related to JavaScript.
The only mention of Java enums I have come across is a very brief Codecademy doc: https://www.codecademy.com/resources/docs/java/enums
However, if you do a web search, there are a number of tutorials and explanations (articles/videos) about Java enums.
For example,
- https://docs.oracle.com/javase/tutorial/java/javaOO/enum.html
- https://www.freecodecamp.org/news/java-enum-enumeration-in-java-example/
- https://www.programiz.com/java-programming/enums
- https://www.baeldung.com/a-guide-to-java-enums
- https://jenkov.com/tutorials/java/enums.html

Why do you think it gives me -1? Doesn’t my method perform the exact modification it was supposed to perform (see the last challenge here)? 
It may be off topic, but I don’t believe it calls for a whole new one
Consider the case when argument is an empty array. You will go out of bounds when trying to assign a value to firstItem
