If all characters of the string are printed, then a new line is printed. */ public class JREProperties { static public void main(String[] args) { try { boolean bNoAccess = false; if(args.length > 0) { if (args[0].equals("noaccessibility")) bNoAccess = true; } //Find out on what operation system we are running.
