You can tell the parseInt() method what base number system is used by the String that is being parsed.
String hex = "01001101"; int n = Integer.parseInt(hex, 2);

se static method java.lang.Integer.valueOf(), or create java.lang.Integer instance directly using constructor. String s = "123"; try { Integer i = Integer.valueOf(s); // or alternatively, create instance directly Integer i2 = new Integer(s); } catch (java.lang.NumberFormatException ex) { // s is not an integer } |
