Java Programming – 100+ Q&A on Syntax, Loops, Java Features, Random, Scanner – CS101

This document includes 100+ exam-focused Java programming questions and verified answers, tailored to the Intro to Java Programming (CS101) course for the 2025/2026 academic year. The questions are concise, structured in a flashcard-style Q&A format, and cover fundamental programming concepts, Java syntax, key language features, and basic input/output techniques. Each term or question is followed by a correct answer, making the content suitable for rapid revision, flashcard learning, and theory test preparation. This resource is highly valuable for first-year students in Computer Science, Software Engineering, and Information Technology, especially those preparing for terminology-heavy quizzes or certification exams like OCAJP. The document also integrates Java language features, object-oriented principles, and Java's control flow tools, including loops and conditionals. Key topics covered include: Java Basics & Syntax: class, method, arguments, method headers, Sln, import statements Primitive Data Types: byte, short, int, long, float, double, char, boolean — including memory order and type groupings Control Flow & Conditionals: if, else, do-while, while, and for loops with their logic and flow conditions Java Language Features: platform independence, security, simplicity, architecture neutrality, object orientation Object-Oriented Terms: instance, class, object creation (new keyword), method vs state vs attribute Java Development Tools: JDK, IDEs, scanner utilities, Java import structure, JVM Constants & Modifiers: final keyword for constants, visibility through access modifiers Random Number Generation: Random rnd = new Random();, type casting for byte, use of nextFloat() Input Handling: Scanner object creation and use, reading from S Comments & Documentation: types of comments in Java and their purpose Java Compilation Workflow: code-to-bytecode process, architecture portability This content is ideal for: Students enrolled in CS101 or introductory Java courses Java beginners using structured Q&A to memorize key programming terms Tutors building flashcards or entry-level quizzes Exam candidates preparing for Java-focused MCQ and short-answer assessments Self-learners aiming to gain fluency with Java’s core syntax and feature set The document’s format ensures quick scanning, exam readiness, and memory reinforcement, making it a must-have for first-semester Java students.
