Java SE 8 Programmer I

The 1Z0-808 covers a lot of ground - from primitive data types all the way to lambdas and the new date-time API. I come from a C background so the OOP sections were where I needed the most work. NerdExam built that confidence methodically.

Solid coverage of Java class design and encapsulation. A few questions felt repetitive, but the explanations were clearer than anything else I found while prepping for 1Z0-808.

Held Java SE 7 certification for years and needed the upgrade path. The lambda and stream-focused questions here covered exactly the delta between versions.

The streams API and functional interfaces were my weak spots going in. NerdExam's explanations actually connected the dots and I cleared the 1Z0-808 on my second attempt.

Not every question matched the difficulty of the actual 1Z0-808, but the Java Collections Framework coverage was genuinely strong. The generics and iterator questions in particular filled gaps other platforms missed. I would pair this with the official Oracle docs for anything outside collections.

Exception handling tripped me up everywhere else. Not here.
