How to Convert String Object to byte primitive

/*
 * Here we will learn to convert String Object to byte primitives.
 */
public class ConvertStringTobytePrimitive {
	public static void main(String[] args) {
		String strObj = "100";

		/**
		 * Constructs a newly allocated Byte object that represents the byte
		 * value indicated by the String parameter. The string is converted to a
		 * byte value in exactly the manner used by the parseByte method for
		 * radix 10.
		 */
		Byte byteObj = new Byte(strObj);
		/*
		 * Byte class extends Number abstract class and overrides methods from
		 * Number class which returns the different type of primitives
		 * datatype().
		 *
		 * 1- byteValue()  : Returns byte
		 * 2- shortValue() : Returns short
		 * 3- intValue()   : Returns int
		 * 4- longValue()  : Returns long
		 * 5- floatValue() : Returns float
		 * 6- doubleValue(): Returns double

		byte bytePrimitive = byteObj.byteValue();

		System.out.println("Value of byte primitive :"+bytePrimitive);
	}
