What do you know about the main() function in Java?

Standard entry point in a Java application.

public static void main(String[] args) {
    // Application code
}

• public: Access modifier that allows the method to be called from anywhere. The JRE must be able to call main to start the program.
• static: Allows the method to be called without creating an instance of the class. The JRE does not create an object to run main.
• void: The method does not return any value.
• main: The name of the method, defined by the Java specification.
• String[] args: An array of string arguments passed when the program is launched from the command line.

The JVM looks for a method with this signature to start program execution. If main is not found or has an incorrect signature, the program will not start.
