As discussed above, an interface can not implement another interface. It has to extend the other interface. See the below example where we have two interfaces Inf1 and Inf2. Inf2 extends Inf1 so If class implem
Java can help reduce costs, drive innovation, & improve application services; the #1 programming language for IoT, enterprise architecture, and cloud computing.
Sometime back I wrote a post aboutJava Callable Futureinterfaces that we can use to get the concurrent processing benefits of threads as well as they are capable of returning value to the calling program. FutureTask is base concrete implementation of Future interface and provides asynchronous process...
Example 2:Let us take a real world example for better understanding of interface. Suppose we may want to take a interface called Fly and this interface may have methods like goDown() and goForward(). These methods would not contain any logic (i.e. without any implementation). But each cl...
This example separates the interfaces, remote object implementation, and client code into three packages: compute–ComputeandTaskinterfaces engine–ComputeEngineimplementation class client–ComputePiclient code andPitask implementation First, you need to build the interface JAR file to provide to server and...
Learn about the IntFunction interface in Java with examples. Understand its usage and how to implement it effectively in your Java applications.
In fact, it was originally called “LiveScript” and was part of Netscape's “LiveWire” Common Gateway Interface (CGI) alternative. The similarities in the name are pure marketing, as it was intended to capalitize on the popularity of the object-oriented programming language Java. On the ...
