    Its a language feature that allows you to declare a method that will take any number of arguments.

    Accordingly, you use it when you don’t/can’t know how many arguments you will pass to the method. Look at the String.format method. In the method declaration, the final parameter is Object... args which indicates that format can take any number of arguments.
