	Basic Data Types: (Single Value Container) | PRIMITIVE TYPES
		char	1 byte					Range: 2Pow8 -> 256
										                -128 to 0 to 127
				0 0 0 0  0 0 0 0

		char ch = 'A';		

		char ch = 65;

		Numbers:
		short s = 10; 2 bytes
		int i = 10;	  4
		long l = 100; 8

		long int li = 10000000;

		float f = 3.3;  4
