Introduction to Advanced Java course

Advanced Java everything beyond that core Java Training is especially defined APIs in the Java Enterprise Edition contains Servlet programming, Web Services, persistence-API, etc. It is a Web & Enterprise application development platform that follows basically the client & server architecture.

Advanced Java Tutorial: need for Advance Java

Below I have listed some important advantages of Advance Java:

1. Advance Java-i.e., JEE (Java Enterprise Edition) you cannot understand the library, the Client-Server architecture for the development of Web applications are supported by the core Java.

2. J2EE is platform-independent, Java-Centric environment for developing, building and deployment of Web-based applications online. It also consists of a set of services, APIs, and protocols that provide the functionality for developing multi-tiered, web-based applications is necessary.

3. 3. 4. You can work with Web and application servers such as Apache Tomcat, Glassfish, etc.and understand communication via HTTP protocol. But in Core Java it is not possible.

4. 4. 4. There are many Advance Java frameworks such as Spring,JSF, Struts etc.with which you can develop secure transaction-based web apps for domains such as e-Commerce, Banking, Legal, Financial, Healthcare, Inventory etc.

5. What do you mean? To work and understand the hot technologies like Hadoop and Cloud services, you should be prepared with core and advanced Java concepts.

I hope you understand why Advanced Java is essential. For your better understanding, I have divided this article into three sections. Each of these sections deals with one of the most important concepts of advanced Java:

1. JDBC (Java database connectivity)

2. Java Servlets

3. JSP(Java Servlet pages)

Let’s start our discussion and understand the concept of Java database connectivity, a useful tool for interacting with the database.

https://www.exltech.in/java-training.html

Advanced Java Tutorial: introduction to JDBC

JDBC is a standard Java API for database-independent connectivity between the Java programming language and a variety of databases. This program interface allows you to encode the access request statements in the Structured Query Language (SQL). They are then passed to the program that manages the database. It’s mainly about opening a connection, creating a SQL database, running SQL queries, and then getting to the output.

We can use JDBC API to tabular data stored in any relational database. With the help of the JDBC API we can store, update, delete and retrieve data from the databases. It is similar to Microsoft’s Open Database Connectivity (ODBC).

For a better understanding of JDBC’s work, we delve deeper into the topic and understand the architecture behind Java Database Connectivity.

Advanced Java Tutorial: JDBC architecture

The JDBC API supports both two-tier and three-tier processing models for database access.

JDBC API: this provides the application-to-JDBC Manager connection.

JDBC driver API: This supports the JDBC Manager-to-Driver connection.

The JDBC API uses a driver Manager and database specific drivers to connect to heterogeneous databases transparently. The JDBC driver manager ensures that the correct driver is used to access each data source. The driver manager supports multiple concurrent drivers connected to multiple heterogeneous databases.

ExlTech promises to provide you with best Java training and with all interview preparation and placement guarantee and soft skills training. Our faculties are very supportive, they provide technical support even after the placement of the candidates for their career growth. This is the best training institute in Pune to start your career in JAVA, where you get best practical oriented Java Training with 100% Placement Assistance.

Advanced Java Tutorial: Common JDBC components

The JDBC API provides the following interfaces and classes

DriverManager is used to manage a list of database drivers. The first driver that recognizes a specific Protocol, JDBC, is used to establish a database connection.

river is an interface that communicates with the database server. It also abstracts the details associated with working with driver objects.

Connection is an interface that contains all methods to connect to a database. The connection object represents the communication context, i.e. all communication with the database is only carried out via connection object.

Let’s go to the next topic and look at the steps to create a JDBC application.

Advanced Java Tutorial: steps to create JDBC application

To create JDBC application, we need to follow some steps. Let’s see what they are.

1. 1. 1. Import the packages: you must include the packages containing the JDBC classes for database programming. Mostly with import java.SQL.* will be sufficient.

2. Register the JDBC driver: you must initialize a driver so you can open a communication channel with the database.

3. 3. 4. Here, you can use the getConnection() method to create a connection object that represents a physical connection to the database.

4. Run query: Requires you to create and send a SQL statement to the database with an object of type statement.

5. What do you mean? Extracting data from result set: requires that you use the appropriate getXXX () method to retrieve the data from the result set.

6. What are you doing? Environment cleanup: requires the explicit closure of all database resources compared to the JVM garbage collection.

How do I use inheritance in Java?

Java class supports reuse through inheritance and composition. This two-part tutorial shows you how to use inheritance in your Java programs. In Part 1, Learn how to use the extends keyword to derive a child from a parent class. In part 2 you will visit java.long.Object, this is the superclass of Java, from which any other class inherits.

All freshers who willing to make career in java ,Java certification courseis a essential to all freshers.

To complete your knowledge about inheritance, check my Java tip, if you want to use composition vs inheritance. Learn why composition is an important addition to inheritance and how to use it to avoid encapsulation problems in your Java programs.

To complete your knowledge about inheritance, check my Java tip, if you want to use composition vs inheritance. Learn why composition is an important addition to inheritance and how to use it to avoid encapsulation problems in your Java programs.

Java Inheritance: Two Examples

Inheritance is a programming construct that software developers use to create is-a relationships between categories. By inheritance, we can derive more specific categories from more generic ones. The more specific category is a type of generic category. For example, a current account is a type of account where you can deposit and withdraw funds. Similarly, a truck is a kind of vehicle for towing large objects.

Inheritance can descend through multiple levels, leading to more and more specific categories. As an example, figure shows the number 1 car and truck inherit from vehicle; Combi inherit from car, and garbage truck inherit from truck. Arrows show from more specific “child” categories (below) to less specific “parents”categories (above).

Jeff Friesen

Figure 1. A few inheritance hierarchies are rooted in the common vehicle category

This example demonstrates single inheritance in which a child category inherits state and behavior from an immediate parent category. In contrast, multiple inheritance a child category to inherit state and behavior from two or more parent categories. The hierarchy in Figure 2 illustrates the Multiple Inheritance.

Jeff Friesen

https://www.exltech.in/java-training.html

Figure 2. Hovercraft multiply inherits from land vehicle and watercraft categories

Categories are described by classes. Java supports single inheritance through class extension, in which a class inherits directly accessible fields and methods from another class by extending this class. However, Java does not support multiple inheritance through the class extension.

When you view an inheritance hierarchy, you can easily detect multiple inherits by the presence of a diamond pattern. Figure 2 shows this pattern in the context of vehicle, land vehicle, watercraft and hovercraft.

The keyword extends

Java supports the class extension using the extends keyword. If present, extends specifies a parent-child relationship between two classes. Below I use extended to a relationship between the classes vehicle and car, and then between Account and SavingsAccount:

How do I implement command Design pattern in the Java programming course with example

It’s a good idea to save the project, because that will allow you to change the project in case you decide to do something different with future sliders. There are many Java programming course tutorials that you will find to learn design patterns, but not really talked about a particular design pattern in depth. So today we learn one of the important design patterns, which is often overlooked by Java developers.

Yes, I’m talking about the command pattern that can help you write flexible, loosely coupled code to implement actions and events in your application. In simple terms, the command design pattern is used to separate a request for an action from the object that actually performs the action. This decoupling between Invoker and Receiver object provides a uniform way to perform different types of actions. This decoupling is achieved with a command object, which is usually an interface to methods such as execute ().

Java Programming Course

The Requestor or Invoker only knows Command object and does not care about the actual object that processes the request, which may be different. This transparency leads to cleaner code on the Invoker page and also allows the ability to do several intelligent things on the command page.

Your command object can be so stupid, how the request delegate to the recipient and can be as smart as the record of the last command for implementing UNDO and Redo functionality.

The command pattern ensures that your code with the open closed design principle, the O of SOLID design principles, compliant, which means that adding a new command would be very easy to create a new implementation of the Command interface and the Invoker code is not affected.

https://www.exltech.in/java-training.html

The Command pattern is popular in GUI applications, where we use a lot of commands, e.g. Open, Close, Save, cut, Copy, Paste, and appropriate UNDO and REDO operations. You can also see the Java Design Patterns Masterclass, which not only covers command patterns and has recently been updated to Java SE 8.

1. Command Pattern-Terminology

Before proceeding and implementing a command pattern in Java, we will familiarize ourselves with the terminology used in this pattern.

Client-creates concrete command object and configure with recipient

Invoker-Who hold command, and calls execute () method on the Command object

Recipient-actual object that processes the request

Command-Interface that handles the request from the Invoker and delegates it to the recipient

ConcreteCommand – implementation of the command interface for a specific task

UML diagram of the command Design Pattern

Here is the UML diagram of the command design pattern, that makes things clearer.

You can see that the Client has a reference to a callback interface that has a generic method execute(). The individual commands implement this interface and provide an implementation, which is nothing else than delegating to the actual object.

The most important thing is that the client does not know about the actual object that performs an action on behalf of these commands. This decoupling leads to flexible code and makes it easy to add new commands without affecting the client code. 

2. Command design pattern in Java-example

Here is our sample program to demonstrate how to use the command pattern in Java.

This Java Certification course exams, formerly known as Sun Java Certification exams, are industry-recognized certifications in Java technology. It focuses on key roles in software application development and enterprise architecture. Each certification is central to the learning process as it provides validation of skill sets for specific job roles.

This class represents a Client of the command pattern

// Invoker calls the command

Menu.runCommand (“create”);

Menu.runCommand (“delete”);
