    Quick check if a String argument is actually an int?

    I have code that does certain stuff if it gets an intger argument, and other stuff if it is String. How can I quickly check if one of my args from command line is actually an integer without doing a parseInt and catching an exception if it is not?# Thanks

    Center align the contents of a TextField

    Sounds basic but when I write tN = new TextField("1"); tN.setAlignment(CENTER); I get "cannot find symbol" error, despite the JAVA Api says I should be able to. Any ideas for center alignment of text field? Thanks.
