javacoding-styleargument-passing

Is there a difference between main(String args[]) and main(String[] args)?

Is there a difference between:

public void main(String args[]) { ... }

and

public void main(String[] args) { ... }

I don't believe so, but I am wondering.

Solution

  • Semantically, they are identical. However, I'd recommend using the latter syntax (String[] args) when declaring arrays. The former syntax is there mainly for compatibility with C syntax.

    Since String[], as a whole, is the type of the object in Java, it's more consistent and clear not to split it up.

    A similar question addresses the [] after method argument list.
