Integer.parseInt(string); //The best possible way!
Integer.valueOf(string); //It returns an object (Integer) not a raw type (int)!
Integer.decode(string); //It can decode from BIN, HEX and OCT as well as DEC format!
NumberUtils.toInt(string); //It can be imported from

P.S. Casting a string to an int (e.g. (int)string) will not compile!
