We would like to know how to convert String to byte.
// w w w .ja v a 2 s . co m public class Main { public static void main(String[] args) { String s = "65"; byte b = Byte.valueOf(s); System.out.println(b); // Causes a NumberFormatException since the value is out of range System.out.println(Byte.valueOf("129")); } }
The code above generates the following result.
