This document contains 8 questions that are part of an examination for a 7th semester computer engineering course covering Java and JEE technologies. It provides instructions to answer 5 full questions out of the 8, with at least 2 questions from each part (A and B). Part A covers core Java concepts like object-oriented programming, applets, events, AWT vs Swing, and GUI components. Part B focuses on more advanced Java EE topics such as JDBC, transactions, servlets, cookies, sessions, JSP, and RMI. Students are asked to explain, define, write examples, and compare/contrast various Java and Java EE programming concepts and technologies.
