Wrapper Construtores - Resum

		1 - Wrapper objects are immutable. Once they have been given a value, that value cannot be changed.
		
		2 - Every Wrapper, except Character, provide two constructor: a primitive value and String representation
			2.1 - A primitive value*/
				Float float1 = new Float(1.11f);
				Integer integer1 = new Integer(10);
				Boolean boolean1 = new Boolean(true);
				Boolean boolean2 = new Boolean(false);

				System.out.println("integer1...: " + integer1);
				System.out.println("boolean1...: " + boolean1);
				System.out.println("boolean2...: " + boolean2);
				System.out.println("float1.....: " + float1 + "\n");/*
						
			2.2 - String representation*/
				Float float2 = new Float("2.22f");
				Integer integer2 = new Integer("15");
				Boolean boolean3 = new Boolean("true");
				Boolean boolean4 = new Boolean("false");
				
				System.out.println("integer2...: " + integer2);
				System.out.println("boolean3...: " + boolean3);
				System.out.println("boolean4...: " + boolean4);
				System.out.println("float2.....: " + float2 + "\n");/*
		
			2.3 - In the constructor "new Float" accept both double and float value and their String representations. For instance:*/
				Float float3 = new Float(3.33d);
				Float float4 = new Float(4.44f);
			
				Float float5 = new Float("5.55d");
				Float float6 = new Float("6.66f");
				
				System.out.println("float3.....: " + float3);
				System.out.println("float4.....: " + float4);
				System.out.println("float5.....: " + float5);
				System.out.println("float6.....: " + float6 + "\n");/*
			
			2.4 - Boolean object can be used as test boolean since java 5*/
				Boolean boolean5 = new Boolean(true);
				if(boolean5) System.out.println("boolean5...: " + boolean5); /* 
				
			2.5 - There is no default constructor for Boolean Wrapper 
				Boolean boolean6 = new Boolean();
				System.out.println("boolean6..: " + boolean6);
				
				
		3 - The Character case we just have one constructor available for us:
			Character character = new Character('A');
			System.out.println("character..: " + character + "\n");/*
		
		4 - A very interesting thing happens when we try put more than one character in Character constructor as we can see below
			Character character2 = new Character('BB');
			System.out.println("character2..: " + character2 + "\n");*/
