The static method Integer.parseInt will do the trick

There is a danger that the string does not represent a valid number in which case an exception will be raised.

There are plenty of similar routines such as: Float.parseFloat Long.parseLong Double.parseDouble Boolean.parseBoolean

The value "1234" is a string, you need to treat it as a num ber - to add 1, giving 1235.
