Study Notes

Java Fundamentals

  • Bytecode is the instruction set for the Java Virtual Machine (JVM), generated from source files by the compiler.

Memory Management

  • Garbage Collector is an automated process that deletes code that's no longer needed or used.

Development Environment

  • JDK (Java Development Kit) is the environment used to write Java programs.
  • JVM (Java Virtual Machine) is the machine that executes bytecode.
  • JRE (Java Runtime Environment) provides access to memory and other system resources, such as program files.

Programming Paradigm

  • OOP (Object Oriented Programming) is a primary paradigm in modern software development, focused on objects as primitives, not specific actions; each object is created/instantiated from a class.

Platform Compatibility

  • Platform Independent software runs on a variety of operating systems or hardware platforms.

Web Development

  • Web Development refers to the tasks associated with creating, building, and maintaining websites.

Programming Concepts

  • Multithreaded programming is a concept where an application can create a small unit of tasks to execute in parallel.
  • Dynamic programming is based on user input and provides an output.
  • Robust programming is the ability to handle errors efficiently.
  • Portable programming is the ability to be performed on any platform.
