What is binary code?
A system using 0s and 1s to represent instructions for computers.
Define a low-level programming language.
A language that interacts directly with the hardware, like Assembly.
What is a high-level programming language?
A language designed to be easier for humans to read and write, like Java.
What is the Java Virtual Machine (JVM)?
A runtime environment that executes Java bytecode, enabling platform independence.
What is an Integrated Development Environment (IDE)?
A software application that provides comprehensive facilities to computer programmers for software development.
Define 'object-oriented programming'.
A programming paradigm based on 'objects', which contain data and code: data in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods).
What is bytecode?
An intermediate representation of Java code after compilation, executed by the JVM.
Define 'multithreading'.
The ability of a program to execute multiple parts (threads) concurrently.
What is a compiler?
A program that translates high-level language code into machine code or bytecode.
What is platform independence?
The ability of a program to run on different operating systems without modification.
Why are high-level languages used?
They are easier for humans to understand, write, and maintain compared to low-level languages.
What is the significance of the JVM for Java?
It allows Java code to be platform-independent, enabling 'write once, run anywhere'.
Explain the importance of the 'code once, run anywhere' principle.
It reduces development costs and ensures applications can run on various platforms without modification.
Why is Java considered a secure language?
It has built-in security features that help resist various types of attacks.
What makes Java a distributed language?
It can connect easily with internet resources and file systems.
What is the role of an IDE in software development?
It provides tools for writing, compiling, debugging, and running code, streamlining the development process.
Explain the concept of object-oriented programming.
It is a programming paradigm that organizes software design around data, or objects, rather than functions and logic.
Why is multithreading useful?
It allows programs to perform multiple tasks concurrently, improving performance and responsiveness.
What is the benefit of Java being a dynamic language?
It can add functionality with libraries at runtime, making it flexible and extensible.
What is the role of a compiler in programming?
It translates human-readable code into machine-executable code.
What are the differences between low-level and high-level languages?
Low-level: close to hardware, difficult to read | High-level: easier to read, requires translation.
Compare and contrast Eclipse, IntelliJ, and VS Code.
Eclipse: Open-source, customizable | IntelliJ: Powerful, feature-rich | VS Code: Lightweight, versatile.
