why dont you print the args `for(String s: args){ System.out.println("arg: " + s); }` – Eric G Dec 16 '15 at 16:52

Is that your complete command line? `23 * 2` will be parsed by most shells as arguments `"23"` `"*"` and `"2"` but your shell seems different... – billc.cn Dec 16 '15 at 16:53

On Windows, you would get what you're expecting.
On Linux, the command shell is applying wildcard expansion, replacing the * with names of all the files in the current directory.
To prevent wildcard expansion, quote the parameter (from Stop shell wildcard character expansion?):

1or possibly the OP wants java Application '23 * 2' - that is, a single argument to main – FredK Dec 16 '15 at 17:05
