One example of inner interface used in java standard library is java.util.Map and Java.util.Map.Entry. Here java.util.Map is used also as a namespace. Entry does not belong to the global scope, which means there

For example, in a future release, synchronization may fail. Callers should make no assumptions about the identity of the returned instances. Factories are free to create new instances or reuse existing ones. They are serialized as specified on the Serialized Form page. This interface...
The implementation type of theSetin the preceding example isHashSet, which makes no guarantees as to the order of the elements in theSet. If you want the program to print the word list in alphabetical order, merely change theSet's implementation type fromHashSettoTreeSet. Making this trivial...
To implement this interface, the name of your class would change (to a particular brand of bicycle, for example, such as ACMEBicycle), and you'd use the implements keyword in the class declaration: class ACMEBicycle implements Bicycle { int cadence = 0; int speed = 0; int gear = 1; ...
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 ...
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 ...
In addition to the predefined implementations in Collectors, the static factory methods #of(Supplier, BiConsumer, BinaryOperator, Characteristics...) can be used to construct collectors. For example, you could create a collector that accumulates widgets into a TreeSet with:text...

For example, the ZipFile class in Fig. 1 declares a native method named open. The actual implementation of the open method is implemented in C. Once declared, native methods are invoked in Java in the same way as how Java methods are invoked. We define a JNI application as a set of ...
