Convert String to byte

This example shows how to convert a String to a byte.
The String can only contain digits (or start with the - sign) and the number has to be within the byte range, otherwise a NumberFormatException will be thrown.
The output from the code below is:
65
Tried to convert an invalid value
　
　
/**

* @author chintan patel

public class Main {
/**
* Example method for converting a String to a byte
*/
public void convertStringToByte() {
try {
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"));
} catch (NumberFormatException ex) {
System.out.println("Tried to convert an invalid value");
}
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
new Main().convertStringToByte();
}
}
