Java Quiz

Java Programming Paradigm

• Java primarily follows the object-oriented programming (OOP) paradigm, emphasizing the use of objects to represent data and methods for handling that data.
• OOP principles in Java include encapsulation, inheritance, and polymorphism, enabling modular and reusable code.

Design Goals of Java

• The main goal of Java's design is to be platform-independent, allowing code to run on any device with a Java Virtual Machine (JVM) without modification.
• Java was developed with a focus on security, making it suitable for web applications through features like the sandboxing of code execution.

Bytecode in Java

• Bytecode is the compiled format of Java source code, designed to be executed by the JVM, ensuring portability across different platforms.
• Java programs are compiled into bytecode, which is platform-neutral, meaning it can run on any operating system that has the JVM installed.

Syntax Comparison

• The syntax of Java is similar to C and C++, which aids programmers familiar with these languages in transitioning to Java.
• Key differences include elimination of pointers in Java, reduced complexity, and the mandatory use of object-oriented concepts, which differs from the more flexible structures seen in C and C++.

Java's Dynamic Capabilities

• Java’s runtime environment provides dynamic capabilities such as reflection, enabling runtime inspection and modification of classes and objects.
• Features like exception handling and automatic garbage collection contribute to Java's dynamic nature by managing resources efficiently during program execution.
