    A Java program follows a well-defined structure that ensures clarity, maintainability, and proper execution flow. Every Java application is built around classes, with one containing the main() method as the entry point.

    Core components of a Java program include:

    • Package declaration (optional) ā€“ Groups related classes to organize code and avoid naming conflicts.

    • Import statements (optional) ā€“ Allow usage of classes from other packages.

    • Class definition ā€“ Blueprint containing variables (data members) and methods (functions).

    • Main method ā€“ public static void main(String[] args) is the starting point of execution.

    • Statements ā€“ Instructions inside methods that define program logic.

    Example:

    // Package declaration (optional)
    package myfirstprogram;

    // Import statement (optional)
    import java.util.*;

    // Class definition
    public class HelloWorld {

    // Main method ā€“ entry point
    public static void main(String[] args) {
    System.out.println("Hello, World!"); // Statement
    }
    }
    Gekopieerd.
