If you are talking about the String "1234" with only numbers in it, then you can use Integer.parseInt(yourStringWithonlyNumbers).
This will return its int value.

Hi,
Can I convert a string or Vector element which contains some numbers into and Int ?
A Vector can't contain primitives so your numbers inside it has to be stored as a String or an Integer. Cast it back after retrieval. If it's a String parse it back as above (or it will throw a NumberFormatException in case of failure). If it's an Integer use intValue() to get your int.
