The Java Development Kit When you download a Java Development Kit JDK , you get — in addition to the compiler and other tools — a complete class library of prebuilt utilities that help you accomplish most common application-development tasks.
The JRE is available for multiple platforms. Although you can use these tools to develop your applications, most developers appreciate the additional functionality, task management, and visual interface of an IDE.
Eclipse is a popular open source IDE for Java development. Eclipse handles basic tasks, such as code compilation and debugging, so that you can focus on writing and testing code.

In addition, you can use Eclipse to organize source code files into projects, compile and test those projects, and store project files in any number of source repositories. If you download one of the Eclipse bundles, it will come with the JDK already.
Agree to the license terms for the version you want to download. Choose the download that matches your operating system and chip architecture. Windows Save the file to your hard drive when prompted. When the download is complete, run the install program. OS X When the download is complete, double-click it to mount it. Run the install program. You do not get to choose where the JDK is installed. You now have a Java environment on your computer. Install Eclipse Browse to the Eclipse packages downloads page.
Under Download Links on the right side, choose your platform the site might already have sniffed out your OS type. Click the mirror you want to download from; then, save the file to your hard drive. When the download finishes, open the file and run the installation program, accepting the defaults.
To set up your Eclipse development environment: Launch Eclipse from your local hard disk. When asked which workspace you want to open, choose the default. Close the Welcome to Eclipse window. The welcome window is displayed each time you enter a new workspace. Figure 1 shows this selection highlighted in the Eclipse setup window for the JRE. Figure 1. Eclipse is now set up and ready for you to create projects, and compile and run Java code.
The next section familiarizes you with Eclipse. This section is a brief hands-on introduction to using Eclipse for Java development.
The Eclipse development environment The Eclipse development environment has four main components: Workspace Perspectives Views The primary unit of organization in Eclipse is the workspace. A workspace contains all of your projects. A perspective is a way of looking at each project hence the name , and within a perspective are one or more views. Figure 2 shows the Java perspective, which is the default perspective for Eclipse.

You see this perspective when you start Eclipse. Figure 2. Eclipse Java perspective The Java perspective contains the tools that you need to begin writing Java applications. Each tabbed window shown in Figure 2 is a view for the Java perspective.
Package Explorer and Outline are two particularly useful views. The Eclipse environment is highly configurable. Each view is dockable, so you can move it around in the Java perspective and place it where you want it. For now, though, stick with the default perspective and view setup.
Figure 3. New Java Project wizard Enter Tutorial as the project name and use the workspace location that you opened when you opened Eclipse.
Click Finish to accept the project setup and create the project. You have now created a new Eclipse Java project and source folder.
Your development environment is ready for action. Object-oriented programming concepts and principles The Java language is mostly object oriented. The connection object represents communication context, i. To insert the values in the created database, you can refer to the below code.
I will be writing the code only for step 4. Rest of the code remains the same as above. Establish a connection with a data source. Send queries and update statements to the data source. Process the results.

For example, the use of JDBC drivers enables you to open a database connection to interact with it by sending SQL or database commands. When Java first came out, this was a useful driver because most databases only supported ODBC access but now this type of driver is recommended only for experimental use or when no other alternative is available.
The vendor-specific driver must be installed on each client machine. The JDBC clients use standard network sockets to communicate with a middleware application server. The socket information is then translated by the middleware application server into the call format required by the DBMS and forwarded to the database server.
This kind of driver is extremely flexible since it requires no code installed on the client and a single driver can actually provide access to multiple databases.
Your application server might use a Type 1, 2, or 4 drivers to communicate with the database. This is the highest performance driver available for the database and is usually provided by the vendor itself. Further, these drivers can be downloaded dynamically.
Because of the proprietary nature of their network protocols, database vendors usually supply type 4 drivers. Subscribe to our youtube channel to get new updates..! So here comes the question, which Driver should be used?The topics in this book are introduced by complete and real-world code examples that you can follow step by step. Furthermore, it explains the UI and API building blocks so you understand the underpinnings of your great application.
