1. The integer types are byte, short, int, and long, occupying 1, 2, 4 and 8 bytes respectively.
2. Variables of type char occupy 2 bytes and can store a single Unicode character code.
3. Integer expressions are evaluated using 64-bit operations  for variables of type long, and using 32-bit operations for all other integer types. You must add a cast for all assignment operations storing a result of type byte, short or char.
4. A cast will be automatically supplied where necessary for op= assignment operations.
5. The floating point types are float and double, occupying 4 and 8 bytes respectively.
6. Values that are outside the range of a floating point type are represented by a special value that is displayed as either infinity or - infinity.
7. Where the result of a floating point calculation is indeterminate, the value is displayed as NaN. Such values are referred to as Not-aNumber.
8. Variables of type boolean can only have either the value true, or the value false.
9. The order of execution of operators in an expression is determined by their precedence. Where operations are of equal precedence, the order of execution is determined by their associativity.
