A Java “Hello World” program is a simple example that demonstrates the basic structure of a Java application. It includes the essential elements such as the class definition, the main method, and a statement to print output to the console. Here’s a basic example:
public class HelloWorld {
public static void main(String[] args) {
System.out.println(“Hello, World!”);
}
}
Class Definition: HelloWorld is the class name. In Java, all code must reside within a class.
Main Method: public static void main(String[] args) is the entry point of the program. It’s where the execution starts.
Print Statement: System.out.println(“Hello, World!”); prints “Hello, World!” to the console.
This program serves as an introduction to Java syntax, class structure, and basic I/O operations.
