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

Question

I\'m just beginning to write programs in Java. What does the following Java code mean?

public static void main(String[] args)

• What

Answer 1

When a java class is executed from the console, the main method is what is called. In order for this to happen, the definition of this main method must be

public static void main(String [])

The fact that this string array is called args is a standard convention, but not strictly required. You would populate this array at the command line when you invoke your program

java MyClass a b c

These are commonly used to define options of your program, for example files to write to or read from.
