Overview of Advanced Java
A small Java application that is downloaded by an ActiveX or Java-enabled web browser. Once it has been downloaded, the applet will run on the user’s computer. Common applets include financial calculators and web drawing programs.
Java – Applet Basics
An applet is a Java program that runs in a Web browser. An applet can be a fully functional Java application because it has the entire Java API at its disposal.
Advanced Java Application
Advanced Java is used for developing the web based application and enterprise application.
Computer software that performs a task or set of tasks, such as word processing or drawing. Applications are also referred to as programs.
Advanced Java Benefits
Java is easy to learn. Java was designed to be easy to use and is therefore easy to write, compile, debug, and learn than other programming languages.
The capacity of a networked connection. Bandwidth determines how much data can be sent along the networked wires. Bandwidth is particularly important for Internet connections, since greater bandwidth also means faster downloads.
To start up a computer. Cold boot means restarting computer after the power is turned off. Warm boot means restarting computer without turning off the power.
Java – Data Structures
The data structures provided by the Java utility package are very powerful and perform a wide range of functions.
Bounded Type Parameters
There may be times when you’ll want to restrict the kinds of types that are allowed to be passed to a type parameter.
The Collection Algorithms
The collections framework defines several algorithms that can be applied to collections and maps. These algorithms are defined as static methods within the Collections class.
Java – Collections Framework
- Implementations, i.e., Classes
Applets inherit a group of event-handling methods from the Container class. The Container class defines several methods, such as processKeyEvent and processMouseEvent, for handling particular types of events, and then one catch-all method called processEvent.
The Enumeration interface isn’t itself a data structure, but it is very important within the context of other data structures. The Enumeration interface defines a means to retrieve successive elements from a data structure.
Java – Generics
Java Generic methods and generic classes enable programmers to specify, with a single method declaration, a set of related methods, or with a single class declaration, a set of related types, respectively.
The Hashtable class provides a means of organizing data based on some user-defined key structure.
Java – Multithreading
Java is a multi-threaded programming language which means we can develop multi-threaded program using Java.
Java – Networking
The term network programming refers to writing programs that execute across multiple devices (computers), in which the devices are all connected to each other using a network.
Socket Class Methods
The java.net.Socket class represents the socket that both the client and the server use to communicate with each other.
Java – Sending Email
To send an email using your Java Application is simple enough but to start with you should have JavaMail API and Java Activation Framework (JAF)installed on your machine.
Java – Serialization
Java provides a mechanism, called object serialization where an object can be represented as a sequence of bytes that includes the object’s data as well as information about the object’s type and the types of data stored in the object.
Serializing an Object
The Object Output Stream class is used to serialize an Object. The following Serialize Demo program instantiates an Employee object and serializes it to a file.
The Stack class implements a last-in-first-out (LIFO) stack of elements.
The Vector class is similar to a traditional Java array, except that it can grow as necessary to accommodate new elements.
