Now, we’re ready to start writing our program. When you start working with Big Data programs, imports can create a lot of confusion. To avoid this, here are all the imports we will use in our project: import org.apache.spark.SparkConf; import org.apache.spark.api.java.JavaPair...
In this tutorial, we shall learn the intuition and realization of encapsulation in Java language with example programs. The below diagram gives an idea about Encapsulation in Java Points to be made from the above diagram are Variables (in the example: height, weight, bmi) are declared private,...
import java.util.Scanner; public class JDBCStoredProcedureRead { public static void main(String[] args) { Connection con = null; CallableStatement stmt = null; //Read User Inputs Scanner input = new Scanner(System.in); System.out.println("Enter Employee ID (int):"); ...
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...
This example shows a Java program creating thread-specific data. Because a Java thread is created on an object, the use of thread-specific data is transparent.
Once the registry is started, you can start the server. You need to make sure that both thecompute.jarfile and the remote object implementation class are in your class path. When you start the compute engine, you need to specify, using thejava.rmi.server.codebaseproperty, where the server...

In a real-world scenario in which a service such as the compute engine is deployed, a developer would likely create a Java Archive (JAR) file that contains theComputeandTaskinterfaces for server classes to implement and client programs to use. Next, a developer, perhaps the same developer of...
