Given an IntelliJ workspace without any projects, how can you create and run a simple “Hello World” program?

• Open a text editor and save a .java file in the workspace

• Create a new Java project, add a package, create a class, and run the class

• Install a new plugin for running Java applications

• Use the command line to compile and run the file outside Eclipse

If you are given source code for a Java class, what is the first step in running it in IntelliJ?

• Save the file to any folder on your computer

• Open IntelliJ and import or create a project for the code

• Double-click the file to execute it

• Convert it into bytecode manually before importing

Which of the following is a key difference between Java, Python, and JavaScript?

• Java is interpreted, while Python and JavaScript are compiled

• Python is typically slower but easier to learn than Java

• JavaScript is strongly typed, unlike Java

• Java cannot be used on multiple platforms

Which is an example of a web application you can build with Java?

• A servlet-based application running on Tomcat

• A machine learning model in TensorFlow

• A mobile app for iOS using Swift

• A C++-based desktop game

What role does the JVM play in running a Java program?

• It directly translates Java source code into machine code

• It stores compiled programs permanently

• It executes Java bytecode on any platform

• It is used only for debugging Java applications

Java’s “write once, run anywhere” principle is possible because:

• Source code is identical on every computer

• Bytecode can run on any JVM implementation

• Java uses the same compiler on all platforms

• Java applications never need recompilation

What is one major benefit of using IntelliJ instead of a plain text editor?

• Eclipse automatically writes code for you

• Eclipse has built-in compiling, debugging, and project management

• Eclipse runs faster than any other IDE

• Eclipse can only be used for Java

Why don’t you need to compile Java source code manually before running it in IntelliJ?

• IntelliJ runs the code as plain text

• IntelliJ automatically compiles the code in the background

• IntelliJ translates Java directly into machine code

• Java does not require compilation

JRE stands for

• Java Run Environment

• Java Run Execution

• Java Runtime Environment

• Java Ready Execution

Java program does not run without below function

• user()

• system()

• main()

• void()
