Java Generics Example Generics was added in Java 5 to providecompile-time type checkingand removing risk ofClassCastExceptionthat was common while working with collection classes. The whole collection framework was re-written to use generics for type-safety. Let’s see how generics help us using ...
JDK 1.0 was shipped with a native method interface. Unfortunately, there were two major reasons that this interface was unsuitable for adoption by other Java VMs. First, the native code accessed fields in Java objects as members of C structures.

Lists (like Java arrays) are zero based. Note that these operations may execute in time proportional to the index value for some implementations (the LinkedList class, for example). Thus, iterating over the elements in a list is typically preferable to indexing through it if the caller does ...
