threadsafe: Instance or static variables will never change asynchronously and so can use compiler optimizations such as assigning to registers. Next modifier -- final -- is also valuable to compilers

final -- Cannot have a subclass for classes
-
cannot be overridden for methods
-
final variables have a constant value e.g.
-
final int ageatdeath = 101;

| 3 |
transient -- specifies that objects are not persistent
|
| 4 |
Note most of these modifiers can be used either for a class or an object -- a particular instance of a class
-
abstract only makes sense for a class and transient is perhaps more useful on an object basis
