[DUPLICATE] why we use (string []args)??

Answer 1

Its simply to add command line arguments to your application

Answer 2

Because main is a method and it has its own arguments which can be specified in command line executions.

Answer 3

string args[] represents command line arguments..... means args is an array of type string.... nd these r the predefined parameters of main method.....that is main can take string arguments.... like we can assign
arg[0]="aman";
arg[1]="java";
we can pass ds parameters in main....method.... and use them
