Common questions
Which Java version should I prepare for?
Most screening questions use features that have been stable since Java 8, such as lambdas and streams. Knowing newer additions like var or records helps, but the fundamentals matter far more.
Do I need to memorise the collections API?
No. You should know when to use ArrayList, HashMap and HashSet, what each one guarantees about order and duplicates, and common methods such as add, get, put and contains.
Why are output-prediction questions so common?
They show whether you understand how Java actually runs code rather than just remembering definitions. Interviewers use them to test references, evaluation order and exception flow quickly.
