Java command line arguments
A command-line argument is an information that directly follows the program's name on the command line when it is executed. To access the command-line arguments inside a Java program is quite easy. They are stored as strings in the String array passed to main( ).
Example
The following program displays all of the command-line arguments that it is called with -
public class CommandLine { public static void main(String args[]) { for(int i = 0; i<args.length; i++) { System.out.println("args[" + i + "]: " + args[i]); } } }
Try executing this program as shown here -
$java CommandLine this is a command line 200 -100
Output
This will produce the following result -
args[0]: this args[1]: is args[2]: a args[3]: command args[4]: line args[5]: 200 args[6]: -100
