Java is a high-level, object-oriented programming language known for its platform independence and versatility. The main parts of Java revolve around its structure and execution flow, which are essential for creating and running Java programs.
Key Components of a Java Program
Class Definition: Every Java program is built around classes. A class serves as the blueprint for objects and contains methods, variables, and constants. At least one class is mandatory in every Java program, and it must include the main() method for execution. Example:
public class HelloWorld {public static void main(String[] args) {System.out.println("Hello, World!");}}コピーしました。✕コピーMain Method: The main() method is the entry point of any standalone Java application. It is where the program begins execution. The syntax is: public static void main(String[] args) public: Makes the method accessible from anywhere. static: Allows the method to be called without creating an object. void: Indicates the method does not return a value. String[] args: Accepts command-line arguments.
