Interface looks like a class but it is not a class. An interface can have methods and variables just like the class but the methods declared in interface are by default abstract (only method signature, no body, see:Java abstract method). Also, the variables declared in an interface are pub...
The following code example illustrates how to use functions in the Invocation API. In this example, the C++ code creates a Java VM and invokes a static method, calledMain.test. For clarity, we omit error checking. #include <jni.h> /* where everything is defined */ ... JavaVM *jvm; ...
If you want to masterfunctional programming, the best place to start is with the Java Function interface. This example will show you four different ways to implement this functional interface in your code — starting with how to use an actual class, and how to create...

The Facebook JNI helpers library is designed to simplify usage of theJava Native Interface. The helpers were implemented to ease the integration of cross-platform mobile code on Android, but there are no Android specifics in the design. It can be used with any Java VM that supports JNI. ...
It is a semantic error to apply this annotation to other fields or methods, including: <ul> <li>fields or methods in a class that is not Serializable<li>fields or methods of the proper structural declaration, but in a type where they are ineffectual. For example, enum types are defined ...

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 ...
