What the questions cover
The OCP Java SE exams are known for careful code reading. The questions cover immutable List.of, records, sealed classes, text blocks, pattern matching with instanceof, exhaustive switch expressions and yield, functional interfaces, stream counts and groupingBy, Optional, try-with-resources, checked exceptions, compound assignment with x++, access modifiers, private interface methods, var, String methods, AtomicInteger, ExecutorService, module exports, LocalDate leap years and equals versus ==.
A sample question explained
"What is printed? int x = 5; x += x++ * 2;" The answer is 15. Compound assignment saves the left operand's value (5) first, then evaluates x++ * 2, which uses 5 and sets x to 6 along the way, giving 10. Finally x becomes 5 + 10 = 15, overwriting the 6. Questions like this reward reading evaluation order precisely.
In this practice set, 17 out of 25 is 68%. Check Oracle's exam page for the current exam (Java SE 17 or 21), its length and passing score.
Getting the most from it
