What is the argument type of a program’s main() method

by

A program’s main() method takes an argument of the String[] type.

In Core Java, the correct answer is:

The argument type of a program’s main() method is an array of strings (String[]). The main() method is the entry point of a Java program, and it accepts an array of strings as its parameter. This array, commonly named args, contains the command-line arguments passed to the program when it is executed. The main() method has the following signature:

java
public static void main(String[] args) {
// Your program logic goes here
}

Here, String[] args represents the array of command-line arguments.
