Explanation of 'String args[]' and static in 'public static void main(String[] args)'

In the main() method in Java, String args[] is an array of strings that holds the command-line arguments passed to the program.

The main() method is the entry point of a Java program and is called by the Java Virtual Machine (JVM) when the program is executed. The main() method has the following signature:

public static void main(String[] args)

The public keyword indicates that the main() method is accessible from anywhere. The static keyword indicates that the main() method is a class method, rather than an instance method. This means that the main() method can be called without creating an instance of the class.

The void keyword indicates that the main() method does not return a value. The args parameter is an array of strings that holds the command-line arguments passed to the program. The name of the array can be anything, but args is a common convention.

For example, if you execute the following command:

java MyProgram arg1 arg2 arg3

The args array will hold the following values:

args[0] = "arg1"
args[1] = "arg2"
args[2] = "arg3"

I hope this helps. Let me know if you have any questions.
