How to Convert String Object to byte primitive

		 * Constructs a newly allocated Byte object that represents the byte
		 * value indicated by the String parameter. The string is converted to a

		/*
		 * Byte class extends Number abstract class and overrides methods from
		 * Number class which returns the different type of primitives

		 * 1- byteValue()  : Returns byte
		 * 2- shortValue() : Returns short
		 * 3- intValue()   : Returns int

		 * 5- floatValue() : Returns float
		 * 6- doubleValue(): Returns double
