Key points to remember

Heads up — this last part is not from Sanfoundry. The 10 questions below were written as extra practice in the style of your syllabus. Every answer was checked by actually compiling and running the code on JDK 21, so the outputs are real — but the questions themselves are predictions, not published material.
