The Legacy Classes In Java

The Legacy Classes In Java

Early version of java did not include the Collection framework. It only defined several classes and interface that provide method for storing objects. When Collection framework were added in J2SE 1.2, the original classes were reengineered to support the collection interface. These classes are also known as Legacy classes. All legacy claases and interface were redesign by JDK 5 to support Generics. 

The following are the legacy classes defined by java.util package 

Dictionary 
HashTable 
Properties 
Stack 
Vector
