Java- Reading Command Line Arguments

Reading Command Line Arguments

1. Common way

    class ReadCmdLineArgs {
        public static void main(String[] args) {
            System.out.println("Command Line Args:");
            System.out.println("------------------");
            if (args.length != 0) {
                for (int i = 0; i < args.length; i++) {
                    System.out.println((i + 1) + ". " + args[i]);
                }
            } else {
                System.out.println("No command line args. specified");
            }
        }
    }
   

2. Another for loop syntax

   class ReadCmdLineArgs {
       public static void main(String[] args) {
           System.out.println("Command Line Args:");
           System.out.println("------------------");
           if (args.length != 0) {
               int i = 1;
               for (String arg: args) {
                   System.out.println((i++) + ". " + arg);
               }
           } else {
               System.out.println("No command line args. specified");
           }
       }
   }
