legacy means synchronization.It is the concept of collection framework (utill package).for example: vector , HashTable, etc are legacy classes( synchronized classes)Synchronized classes gives concept of thread safe means if so many request is coming to access a single resources then it will lock all request except first request and will do process one by one with sequence order (FIFO).

No, in general , leagacy defines a system that was built using older , more complicated technology,  that are now harder to maintain.

Collections have made some Java objects and one interface obsolete. These older legacy structures have not be removed as much legacy code, even in Java itself make use of them. However new programs should be written with collections. The following legacy classes and interface are mentioned here for historical purposes only!

?Enumeration [interface] - Use Iterator		?Dictionary - Use Map
?Vector - Use ArrayList	?Stack -	?Hashtable - Use HashMap

Legacy classes are those classes which are deprecated,which are older and hence they are replaced with new ones.for eg: Enumeration is a legacy class and is superseded by Iterator.
