Log4j is an open source project developed and maintained by Apache. It is part of a bigger open source project known as the Apache Logging Services. The following code sample shows how to use Log4j in its basic configuration. package il.ac.hit.samples; import org.apache.log4j.BasicConfigurator; import org.apache.log4j.Logger; public class SimpleLoop { static Logger logger = Logger.getLogger(“SimpleLoop”); public […]

Generics Implementation in Java PRO
The generic class has the same behavior for all of its possible parametric types. The same generic class can be viewed each time as if it has a different parametric type. For the JVM it doesn’t matter which parametric type we chose to instantiate a generic class with. In all cases, for the JVM it […]
Generics’ Bounded Wild Cards in Java PRO
When using a bounded wild card we can limit the parametric type as if we were saying that it can be any type as long as it extends or implements a specific type we specify. package il.ac.hit.samples; import java.util.Iterator; import java.util.Vector; public class BoundedWildCardSample { public static double calculateTotal(Vector<? extends Shape> vicy) { double sum […]
Generic Type Arrays in Java Limit PRO
When using an array of generic type objects in Java we cannot specify the exact parametric type. This limit exists due to the way generics is implemented in Java (in the compiler level). package il.ac.hit.samples; public class ArraysGenericsLimit { public static void main(String[] args) { MyStack<?> []vec = new MyStack<?>[10]; vec[0] = new MyStack<Rectangle>(); vec[1] […]
