Course content

1 section • 111 lectures • 22h 33m total length

  • JDK, JRE, JVM, JVM Architecture, Path Setting, Class Path Setting26:15

    1. JDK (Java Development Kit)

    • What it is: A software development environment used to develop Java applications.

    • Includes:

      • JRE (Java Runtime Environment)

      • Compiler (javac)

      • Debugger

      • Tools for development (e.g., javadoc, javap)

    • Use: Needed for developing, compiling, and running Java programs.

    2. JRE (Java Runtime Environment)

    • What it is: A part of the JDK used to run Java programs.

    • Includes:

      • JVM

      • Core libraries and other files required for execution

    • Use: Needed only to run Java programs, not to develop them.

    3. JVM (Java Virtual Machine)

    • What it is: An abstract machine that executes Java bytecode.

    • Platform-independent: JVMs are available for many hardware and software platforms.

    • Use: Converts bytecode (.class files) into machine code for execution on the host system.

    4. JVM Architecture

    The JVM consists of several components:

    • Class Loader: Loads .class files (bytecode) into memory.

    • Method Area: Stores class structures like metadata, method info, and constant pool.

    • Heap: Stores objects and class instances.

    • Stack: Stores method calls and local variables (one stack per thread).

    • Program Counter (PC) Register: Holds the address of the current executing instruction.

    • Execution Engine:

      • Interpreter: Interprets bytecode line by line.

      • JIT Compiler (Just-In-Time): Converts bytecode into native code for better performance.

    • Native Method Interface: Enables Java code to interact with native libraries (e.g., C/C++).

    • Native Method Libraries: Platform-specific libraries.

    5. Path Setting

    • Purpose: To run Java commands (java, javac, etc.) from any directory in the command line.

    • How to Set (Windows):

      • Find the JDK bin folder path (e.g., C:\Program Files\Java\jdk-XX\bin)

      • Add it to the system PATH environment variable:

        • Right-click This PC > Properties > Advanced system settings > Environment Variables

        • Under System Variables, find Path, click Edit, and add the JDK bin path.

    6. Class path Setting

    • Purpose: To tell the JVM and compiler where to find user-defined classes and packages.
