Purpose of String args in the psvm of Java

Question

Why do we always pass the argument as String[args]/String[] args to the main method of Java?

Answer 1

Let me give you the complete explanation of the Java main method:

public static void main(String[] args)

• "public" is the access modifier which means main() can be called from anywhere.
• "static" is a keyword which signifies main() doesn't belong to any specific object
• "void" is the return type that means that main() returns no value
• "main" is the name of a function. main() is special because it is the point from where JRE starts the execution of the program.
• "String[]" means we are going to use an array of String type.
• "args" is the name of the String[]. "args" is not a keyword, so you can name it anything else and it would not affect your program

public static void main(String[] parameter)

So basically, String[] args represents a collection of Strings that are separated by a space and can be typed into the program on the terminal directly.
