Study Notes
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.
