When we run above program, you will notice that it doesn’t print anything for sometime becauseget()method of FutureTask waits for the task to get completed and then returns the output object. There is an overloaded method also to wait for only specified amount of time and we are using i...
ThegetLocalHost( )method simply returns theInetAddressobject that represents the local host. ThegetByName( )method returns anInetAddressfor a host name passed to it. If these methods are unable to resolve the host name, they throw anUnknownHostException. On the Internet, it is common for a sing...
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...
For these example policy files, all permissions are granted to the classes in the program's local class path, because the local application code is trusted, but no permissions are granted to code downloaded from other locations. Therefore, the compute engine server restricts the tasks that it ex...
JRE stands for Java Runtime Environment and it contains all the tools and executables that are needed to run Java programs. JDK is the Java Development Kit that contains all the tools and executables that are needed to develop Java programs including the execution of the Java program. In ...
Theclientpackage contains two classes,ComputePi, the main client program, andPi, the client's implementation of theTaskinterface. Assume that userjones, the developer of the client classes, has placedComputePi.javaandPi.javain the directoryC:\home\jones\src\clienton Windows or the directory/home...
Example Program In the following example, Human.java class has variables height, weight and bmi which are private. For each variable, there is a setter and getter. </> Copy package com.tutorialkart.java; /** * @author tutorialkart */ class Human{ private float weight; private float heig...
To run the application, go inside the root directory of the program and execute the following command: mvn exec:java -Dexec.mainClass=com.journaldev.sparkdemo.WordCounter -Dexec.args="input.txt" In this command, we provide Maven with the fully-qualified name of the Main class and ...
Example Java program using Titan 1.0 and TinkerPop 3.0.1 and Titan Server (Gremlin Server) - pluradj/titan-tp3-driver-example
then return the result to our client program, check ourJava Callable Future.Update: From Java 8 onwards, Runnable is a functional interface and we can use lambda expressions to provide it’s implementation rather than using anonymous class. For more details, check outJava 8 Functional Interfaces...
