In Java, the main method is the entry point of the program, and it must have the following signature:
public static void main(String[] args)
The args parameter is an array of strings that contains any command line arguments passed to the program. The name args is just a convention, and it can be replaced with any valid Java identifier. However, it is recommended to use the name args for clarity and consistency with other Java programs.
For example, the following program replaces the args parameter with arguments:
public class Example {
public static void main(String[] arguments) {
System.out.println("Arguments: ");
for (String arg : arguments) {
System.out.println(arg);
}
}
}
In this example, we loop through the arguments array and print each command line argument to the console.
When we run the program with the command line arguments "foo" and "bar", the output will be:
Arguments:
foo
bar
As you can see, the program works as expected, and the name of the args parameter is just a matter of convention. However, it is important to use a descriptive name that reflects the purpose of the parameter for the sake of readability and maintainability.
Can we keep any name instead of args?
