You're trying to print an empty String. Surprise surprise, nothing shows up.

[javanew]

lol i am sorry i forgot to edit it,,
even if it wasnt an empty string it will pirnt nothing

[m00nchile]

If a System.out.println() inside a catch block doesn't print, then no exception was caught.

[javanew]

why no exception was caught ?? i inserted zero, and there must be an exception

Dividing by zero with floats and doubles are handled differently then if you do the same with ints.

double and floats support dividing by 0 by returning infinity. You can get an error if you enter text in there.
