Why is bytevalue not abstract

If you insantiate 10 of your object, you'll have 10 copies of the method in memory, even though they are all the same, until you modify one of them. To be clear though, by shared among object instances, I do not mean to say that the method operates statically on any properties it accesses.

Those properties if defined with this. It's just that you don't end up defining multiple copies of the same method. Why shortValue method are concrete but intValue is abstract into java.

Object java. The specific semantics of the conversion from the numeric value of a particular Number implementation to a given primitive type is defined by the Number implementation in question.

Therefore, conversions may lose information about the overall magnitude of a numeric value, may lose precision, and may even return a result of a different sign than the input. See the documentation of a given Number implementation for conversion details. Returns the value of the specified number as a double , which may involve rounding. Returns the value of the specified number as a float , which may involve rounding.
