ResultSet: When you execute Statement objects, and they generate ResultSet objects, which is a table of data representing a database result set.

Statement Class: A Statement is an interface that represents a SQL statement.

It is through which we send SQL queries to the database.

Connection Class: It acts as a connection session between the Java program and specific database application.

In the above code, the following things need to be kept in mind which are: Right-click and select Add Jar/Library and browse the Library classpath noted down previously.

Now go to Projects toolbar and go to your application’s Libraries. Note down the Library ClassPath and click OK. Thus go to the menubar, under Tools->Libraries, and add MySQL JDBC connector. We need to import libraries that are needed to set up a connection with the database and retrieve data which is done by – DriverManager Class, Connection Class, and Statement Class. Going back to NetBeans, we need to follow these steps for database connectivity:Ĩ. | address | varchar(40) | YES | | NULL | | | Field | Type | Null | Key | Default | Extra | Open MySQL command client, enter password, and type in the following commands to create a new database, new table, and defining the attributes. Now let us create the database to store the data. Now to set the headings, right-click on the table, select Properties -> Model ->Add/delete Columns.ħ. Since we need to display all data in a tabulated form, drag the table widget from the palette onto the design area.

We need to set up different JDBC drivers for different databases.ĭrag Components from palette to design areaĦ.

JDBC Driver: It enables a Java application to interact with the database.

It acts as a communication between the application and the database.

JDBC API: Java Database Connectivity Application Program Interface is a set of interfaces and classes using which you can write Java programs for accessing and manipulating databases.
