To understand what's wrong, you should learn more about streams stuff.

Briefly, if you open stream, then, you should close it, or a memory leak appears.

See http://www.tutorialspoint.com/java/java_files_io.htm for details.

Good luck!

You should close the scanner after using it. Otherwise, you'll get the warning from the compiler.

The simplest way is to add Nommy.close() after the last statement.

You should, however, call it in a finally block or using the try statement: see https://stackoverflow.com/a/15613676/1547337

now ive close it, when i press run its giving this error "Error: Could not find or load main class Port" what dose this mean? – Nehman Jun 14 '15 at 14:59
That's because your class name is not Port, but apples. Try `java apples` – dejvuth Jun 14 '15 at 15:02
sorry but what is is port? – Nehman Jun 14 '15 at 15:43
That's what I should ask you. It's something that doesn't exist. You can see it from the error. – dejvuth Jun 14 '15 at 16:26
