Java's networking classes enable you to implement applications that communicate across a network/remote connection, but the platform also extends into the realm of the Internet and URLs. Java's URL class makes accessing Web resources as easy as accessing a local file. Let's take a look at how you...
Java, has become now undoubtedly the fuel of the development of the Software System Technology.Developers, now thus take the challenge to prove the feelings of Java as the best positive catalyst of their development life's reactions.They feel the Class, as the ultimate classic sense of the...
Multi-dimensional arrays Java, as with most languages, supports multi-dimensional arrays - 1-dimensional, 2-dimensional, 3-dimensional, ... This discusses 2-dimensional arrays, but the same principles apply to higher dimensions. 2-dimensional arrays 2-dimensional arrays are usually...
We can create a thread in Java by extending Thread Class. A better way to create a thread in Java is to implement Runnable interface. A thread can be created by extending Java Thread class also. Now the question arises why implementing Runnable interface is a better approach? Answer is, if the...

This article continues our exploration of the Abstract Window Toolkit (AWT). It examines the standard controls defined by Java. Controls are components that allow a user to interact with your application in various ways—for example; a commonly used control is the push button. The AWT supports...
1. How can you store a copy of an object at the same time other threads may be changing the object's properties? Choice 1 Override writeObject() in ObjectOutputStream to make it synchronized. Choice 2 Clone the object in a block synchronized on the object and serialize the clone. Choice 3...

A thread, by definition is a light weight process. They are used to increase functionality and performance by performing multiple tasks at the same time, i.e. concurrently. There are two methods for implementing threads in Java, Implementing an interface Extending a class I'd assume that...
An initialization block is a block of code between braces that is executed before the object of the class is created. As the execution of the initialization block is dependent on the creation of the object we can easily make a guess that it has two types of object. 1. Non static initialization...

For this connection to work over the Wifi network the user must enter the correct IP address of the phone/computer. It's a bit of a downfall when it comes to the users side since there can be...
Before we understand what Java Serialization is, first we need to understand what serialization means? In computer science, in the context of data storage, serialization is the process of translating data structures or object state into a format that can be stored and reconstructed later in the...
Java is an object-oriented language and as said everything in java is an object. But what about the primitives? They are sort of left out in the world of objects, that is, they cannot participate in the object activities, such as being returned from a method as an object, and being added to a...
