What is "String args[]"? parameter in main method Java

String args[] is a parameter in the main method of a Java program. It is an array of strings that can be used to pass command-line arguments to the program when it is executed.

Here is an example of the main method with the args parameter:

public static void main(String[] args) {
    // code goes here

The args parameter can be used to pass arguments to the program when it is run from the command line. For example, suppose you have a Java program called MyProgram, and you want to pass the arguments "Hello" and "World" to the program when you run it. You could do this by running the following command:

java MyProgram Hello World

Inside the program, you could access the arguments passed on the command line by using the args array. For example, you could print the first argument like this:

System.out.println(args[0]);  // prints "Hello"

You can also use the args array to loop through all of the arguments passed to the program:

for (int i = 0; i < args.length; i++) {
