Programming Basics Quiz

An integrated development environment (IDE) that provides a comprehensive set of tools for writing, compiling, and debugging code.

A programming language developed by Sun Microsystems, known for its platform independence and object-oriented features.

A folder that typically holds the source code, including the .java files, for a Java project.

A simple program that prints the text "Hello, World!" to the console.

A software application that allows developers to write and debug code, commonly used for Java projects.

A programming language used to develop applications with a focus on objects.

A key programming paradigm that uses objects to represent data and actions.

A virtual machine that executes Java bytecode on any platform, ensuring platform independence.

A powerful code editor that provides features like syntax highlighting, debugging, and code completion.

A mechanism that organizes code into reusable blocks, encapsulating data and methods.

Instances of a class, representing real-world entities with specific data and behavior.

Functions within a class that perform specific tasks.

A set of rules for managing access to data members and methods within a class.

A programming language where the code is executed line by line without being compiled into machine code beforehand. This allows for faster development but often results in slower execution.

Programming languages where the code is first compiled into machine code before being executed. This results in faster execution but can be slower to develop.

Languages that combine features of both interpreted and compiled languages. They are typically compiled into bytecode first which is then interpreted by a virtual machine.

The source code of a program written in a programming language. It is plain text that humans can read and understand.

The process of converting source code into machine code that can be understood by the computer.

A program that reads and executes source code line by line without compiling it into machine code.

The language that computers understand directly. It consists of binary instructions that control the hardware.

The process of converting source code into machine code during program execution. This can lead to slower execution speeds.

The JVM is a virtual machine that executes Java bytecode, acting as an intermediary between the compiled code and the underlying operating system. It ensures platform independence, allowing Java programs to run on different operating systems.

The JVM memory footprint is divided into three primary sections: Stack, Heap, and Method Area. Stack is where local variables and method calls are managed. Heap stores objects and data structures. Method Area holds class definitions and static data.

The Class Loader is responsible for loading Java bytecode from .class files into the JVM's Method Area. It ensures that the bytecode is available for execution.

The JVM always starts executing code from the main method. This method serves as the entry point for program execution.

The JVM follows a set of predefined rules to ensure the consistent and reliable execution of Java programs. These rules govern aspects like class loading, execution flow, and memory management.

Primitive variables are fundamental building blocks in Java, representing basic data types such as integers (int), floating-point numbers (double), characters (char), and booleans (boolean).

Primitive variables can be used for arithmetic operations, like addition, subtraction, multiplication, and division, based on their data type.

Java allows you to create variables of different data types such as int, double, char, and boolean to store different kinds of information. The int data type stores whole numbers, double stores decimal numbers, char stores single characters, and boolean stores true or false values.

A variable that can hold a sequence of characters, including letters, numbers, and symbols. It's like a container for text.

To combine two or more Strings together, creating a new String that includes all the characters from the original Strings. This is like joining two pieces of string together.

Instead of performing mathematical addition, it adds two Strings together, creating a new String that includes both original Strings.

Variables can be defined using camelCase, a naming convention where the first word in a variable name starts with a lowercase letter and subsequent words start with an uppercase letter.

Variables need to be declared before they are used. This means that the type of data they hold needs to be specified before they can be assigned values.

A variable can only be declared once. It cannot be re-created with the same name.

In Java, variables are typed, meaning that their type is checked at compile time. This helps catch errors early in the development process.

Primitive variables in Java represent fundamental data types built into the language, such as integers (int), floating-point numbers (double), and characters (char).

A data type representing a sequence of characters enclosed within double quotes. Strings are primarily used to represent text values.

A data type representing whole numbers without decimal places. They are used for calculations and representing numerical values with no fractional parts.

A data type representing numbers with decimal places. They allow for precise representation of values with fractional components.

The process of combining two strings together to create a new string, often using the '+' operator in programming languages. This involves appending the second string to the end of the first string.

A named memory location that holds a specific data value. Variables are essential for storing and manipulating data within a program.

The process of specifying the data type of a variable before using it. This ensures that the variable can only hold values of the specified type.

A specific data type that is built into a programming language, such as int, double, char, or String. Primitive types represent fundamental data units.
