Highlight on essential concepts of advanced Java:

Advanced Java Tutorial: Introduction to JDBC

JDBC, the standard Java API is the API for the database-independent connectivity between the range of the Java programming language and databases. The application program interface works for encoding the access request statements available in the structured query language.

After that, it passes to the program for the management of the database. This involves opening of the connection, creation of the SQL database, executing the queries in SQL, and then arriving at the output. Individuals can also use the JDBC API for accessing the tabular data stored in all the relational databases with the help of this API. You can save, delete, update, as well as fetch data from the databases. It is quite similar in its type to the open database connectivity provided by Microsoft.

JDBC Architecture

The architecture of JDBC API comes supportive of both two-tier as well as three-tier processing models for the database. The layers are JDBC API for the management of application to JDBC manager connection. Again, the JDBC driver API is supportive of the JDBC manager to driver connection.

Common JDBC Components

The interfaces and classes are available in driver manager work for management of the list of database drivers.

Driver Manager gives a recognition of the certain subprotocol under JDBC for establishing a database connection.

The driver works as the Interface for handling the communications with the database server. It also helps in the abstraction of the details associated with Driver objects.

Connection works as the interface for methods required for connection to a database.

Again, the connection object works as the representation of communication context.

Steps to create a JDBC Application:

• Importing the packages
• Registering the JDBC driver
• Opening a connection
• Executing a query
• Extraction of data from the result set
• Cleaning up the environment

Introduction to Servlets

A servlet refers to a Java programming language class for extending the capabilities of servers responsible for hosting applications accessed request-response programming model. These servlets have the ability to respond to any request. They can help with the extension of the applications hosted by web servers.

Servlet Life Cycle

Servlet container using the javax.servlet.Servlet interface helps in the understanding of the Servlet object and management of it.

Stages of the Life Cycle of Servlet

Steps for creating the Servlet:

• Creation of a directory structure
• Creation of a Servlet
• Compiling the Servlet
• Adding mappings to web.xml file
• Starting the server and deployment of the project
• Accessing the servlet
• Session Tracking

Java Server Pages:

JSP or Java Server Pages refers to the technology for the creation of web application similar to Servlet technology. So, basically, its purpose is to function as the extension to Servlet. It can provide more functionality like expression language and JSTL. It consists of HTML tags as well as ad JSP tags. It will favor better Maintenance over Servlet. Other features available are Expression Language, Custom Tags, etc.

Conclusion

By the end of the training course, you will gain deeper insight and understanding of Advanced Java Programming topics. With such learning, you’ll get in-depth concepts of your preferences. So, now start with the objective of learning Advanced java tutorial and develop expertise in the various sections of this course.

What is the Difference Between Core Java and Advanced Java

Java is a general-purpose high-level programming language that helps to build a variety of applications. Java is popular as it provides platform as it provides various features such as independency, security, multithread support. There are two types of Java as Core Java and Advanced Java. Core Java covers the fundamental concepts in the Java programming language. On the other hand, Advanced Java is the next level after Core Java.

Key Areas Covered

Key Terms

Advanced Java, Core Java, Java

What is Core Java

Core Java mainly focuses on building general applications. Java Standard Edition (J2SE) is categorized as Core Java. Core Java mainly covers object-oriented programming concepts. The main OOP pillars are encapsulation, inheritance, abstraction and polymorphism. They are as follows.

Encapsulation – Combines data and methods to a single unit

Inheritance – Allows using an already created class without writing the code from the beginning, improving the code reusability

Polymorphism – Allows writing code in a way that an object can behave in multiple ways

Abstraction – Allows writing the code in a way that hides the implementation details to reduce complexity.

Core Java helps to implement the above concepts when developing software.

In addition, Core Java covers concepts such as swing, AWT, threading and collections. Swing and AWT help to build powerful Graphical User Interfaces (GUIs). Furthermore, threading allows executing multiple processes simultaneously while collections allow manipulating a group of objects. Overall, Core Java covers all the fundamental concepts of Java programming language.

What is Advanced Java

Advanced Java is the level ahead of Core Java, and covers more advanced concepts such as web technologies, and database accessing. Java Enterprise Edition (J2EE) is categorized as Advanced Java.

Advanced Java covers a number of topics. JDBC stands for Java Database Connectivity. It is a standard Java API to build independent connectivity between the Java language based application and databases such as MySQL, MSSQL, and, Oracle. Additionally, Servlets and JSP allow developing dynamic web applications. EJB provide distributed and highly transactional features to build enterprise applications. Furthermore, Java web services help to build SOAP and RESTful web services. They provide a common platform for the applications to communicate with each other.

Relationship Between Core Java and Advanced Java

• Advanced Java depends on Core Java. As a result, it is not possible to develop applications using Advanced Java without Core Java knowledge.

Difference Between Core Java and Advanced Java

Definition

Core Java is the category of Java that covers the fundamental concepts of Java programming language to develop general applications. Advanced Java is the category of Java that covers the advanced concepts to build enterprise applications using Java programming language. Hence, this explains the main difference between Core Java and Advanced Java.

Java Version

Java Standard Edition (J2SE) comes under Core Java while Java Enterprise Edition (J2EE) omes under Advanced Java.

Topics or Areas

OOP, data types, operators, exception handling, threading, swing, and collections are some topics in Core Java. In contrast, database connectivity, web services, Servlets, JSP, EJB, etc. are some topics in Advanced Java.

Architecture

Furthermore, core Java uses single tier architecture. In contrast, Advanced Java uses two-tier architecture. e.g.- client, server architecture. This is a major difference between Core Java and Advanced Java.

Applications

Another ifference between Core Java and Advanced Java is that Core Java helps to build general applications while advanced Java helps to build enterprise level applications. e.g., web applications, etc.

Conclusion

In brief, Core Java and Advanced Java are two types of Java language. The main difference between Core Java and Advanced Java is that Core Java is used to build general applications while Advanced Java is used to build enterprise level applications.
