Pass by value or Pass by Reference?
Short answer: Java is always pass-by-value. What trips people up is what the “value” is: For primitives (int, double, boolean, …): the value is the actual number/bit pattern. You get...

What is Lombok?
Lombok is a compile-time code generator for Java that uses annotations to remove boilerplate (getters, setters, constructors, builders, equals/hashCode, toString, loggers, etc.). It works via annotation processing: your IDE/build runs...

Comparator vs Comparable
TL;DR Comparable → put the natural order inside the class (one order). Comparator → define external strategies outside the class (many orders). Core differences Package & method Comparable<T> (java.lang) →...
