    Question Error while writing Integer.parseInt(args[]) to accept a number

    Hello, I am new to Java, though i am familiar with C, C++ and VB. I cant get through the syntax for accepting a number from the keyboard. Have tried Integer.parseInt(args[0]), but it gives an error. Please help

    Hello cuteanu, welcome to the forums.

    You could use the Scanner class to read user input from the keyboard.

    If you wish to send numbers on the command line when you first launch the application, this will work fine:

        public static void main(String[] args) {
     
            int myInt = Integer.parseInt(args[0]);
            System.out.println(myInt);
     
        }
    Please use [highlight=Java] code [/highlight] tags when posting your code.
