Which of the following is the correct structure for the traditional "Hello World" Java program according to the source?
a) class HelloWorld { main { println("Hello World!"); } } b) public class HelloWorld { public static void main(String[] args) { print("Hello World!"); } } c) public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World!"); } } d) public class Hello_World { public static void main(String[] args) { System.out.println("Hello World!"); } }
How must the main method line (public static void main(String[] args)) be typed?
a) It can be abbreviated for simplicity b) It can be customized based on program requirements c) It must be typed exactly as shown d) The capitalization is flexible
What does the source indicate about errors on a programmer's first attempt?
a) They are rare and indicate a serious problem b) Most programmers encounter errors, and debugging is part of the development process c) They mean the IDE is configured incorrectly d) They only happen with complex programs
What does "Error detection" in an IDE accomplish?
a) Identifies problems during typing, before program execution b) Fixes errors automatically after execution c) Translates human-readable Java into machine code d) Suggests likely continuations for code
What is the critical rule for naming a Java program file?
a) The filename must be all lowercase b) The filename must start with "Java" c) The filename must contain only numbers d) The class name must match the filename exactly, with the .java extension
Is whitespace (like indentation) required for Java compilation?
a) Yes, it will not compile without it b) No, it is not required for compilation c) Only for the main method d) Only when using System.out.println
What component of the Java program performs the actual work of displaying text in the console?
a) The class declaration b) The main method c) The instruction (System.out.println("Hello World!");) d) The curly braces
Which of the following is not one of the fundamental steps in the programming cycle described?
a) Writing code b) Executing code c) Checking the output d) Designing the user interface
What is the function of "Auto-completion" in a modern IDE?
a) Highlights different parts of your code b) Detects errors after program execution c) Suggests likely continuations, reducing typing errors d) Translates code into machine code
If your Java program class is named HelloWorld, how should you save the file?
a) helloworld.java b) HelloWorldProgram.java c) HelloWorld.java d) Hello_World.java
What is the benefit of consistent formatting and indentation in Java code?
a) It makes the code compile faster b) It reduces the memory footprint of the program c) It represents professional practice and improves code readability d) It is a critical requirement for Java program execution
What character terminates an instruction statement in Java, similar to how a period ends a sentence?
a) A colon (:) b) A comma (,) c) A question mark (?) d) A semicolon (;)
What is the final step in the fundamental programming cycle?
a) Writing code b) Executing code c) Checking the output d) Resolving any problems
What is the purpose of "Integrated compilation" in an IDE?
a) To highlight syntax errors in real-time b) To suggest code completions c) To translate human-readable Java into machine code efficiently d) To identify problems during typing
Why is it required for the class name to match the filename exactly in Java? a) To improve code readability
a) To improve code readability b) Java uses the filename to identify which class to execute c) To comply with professional formatting standards d) To speed up program compilation
What is the role of the class declaration (public class HelloWorld) in a Java program?
a) It creates a program container and acts as the organizational structure for instructions b) It indicates where Java should begin program execution c) It performs the actual work of displaying text d) It organizes instructions that belong together using curly braces
What is the role of curly braces {} in a Java program?
a) They define the program's output b) They act as a debugger c) They organize components, indicating which instructions belong together d) They signal the end of the program
What does successfully executing your first program and understanding its structure provide?
a) Advanced debugging skills b) The ability to create complex algorithms c) The foundation for professional coding practices d) Knowledge of advanced programming languages
