send argument to main class by command line with external jar command

I run java application in command line linux with external jar like this :

java -cp ".:commons-net-3.6.jar" FtpClass

how can I send argument to main class by command line ?

Solution

  • You need to specify arguments after class like this 

      java -cp ".:commons-net-3.6.jar" FtpClass A B C

    Assume example

    public class Example {
    public static void main (String[] args) {
        for (String s: args) {
            System.out.println(s);
        }
    }
}

    The following example shows how a user might run Example. 

    java Example Drink Hot Java

    output is

    Drink
Hot
Java
