A package in Java that provides classes for handling events related to graphical user interfaces (GUIs).

Provides an empty implementation of all methods in an event listener interface. This allows programmers to override only the methods they need, simplifying event handling.

A class that provides an empty implementation of all methods in the WindowListener interface, allowing programmers to only override the specific window events they want to handle.

An adapter class for the MouseListener interface, allowing programmers to selectively override specific mouse events.

A class that provides an empty implementation of all methods in the KeyListener interface, allowing programmers to only override the specific key events they want to handle.

The windowClosing method of WindowAdapter is called when the user indicates that they want to close a window, usually by clicking the close button.

A focusGained event occurs when a component gains keyboard focus, meaning it is ready to receive input.

A class that provides an empty implementation of all methods in the FocusListener interface, allowing programmers to only override the specific focus events they want to handle.

An abstract class that is a subclass of ComponentEvent and is used for component input events such as focusing or changing the state of a button.

Inner classes are classes defined within another class. They can access all members of the outer class, including private members.

An inner class that is declared inside the class or interface. It is also known as a nested class.

A special type of inner class that does not have a name. It is created and used in one line of code. These classes can help you write concise code.

Classes that mainly focus on providing empty implementations for methods in interfaces, thus making the programmer's task simpler by overriding only necessary methods.

A concept that simplifies event handling in Java by providing empty implementations of methods within an interface. This makes it easier for programmers to only override the methods they need for specific events.

A type of event that occurs when a user enters a character into a text field. Often used to update the content of the text field in real-time.

A class that defines integer constants for different types of mouse wheel events, including scrolling in blocks or units.

A class that provides methods for sending SQL INSERT, UPDATE, or DELETE statements to the database.

A set of successfully executed statements in the database that are treated as a single unit. These statements can be committed or rolled back.

A class that provides a way for a JDBC program to retrieve data from a database.

A method that returns an array of InetAddress objects that represent all the IP addresses associated with a specific host name.

A class that encapsulates both a numerical IP address and a host name. It allows Java programs to interact with networks by representing the addresses of computers or devices.

A type of JDBC statement that can execute parameterized queries. It represents a precompiled SQL statement that can be executed multiple times with different values.

A type of JDBC statement that allows you to execute stored procedures. It offers a way to interact with database procedures that are already defined.

A method that returns the IP address of the local machine where the program is running.

A method that returns an InetAddress object representing the specified host name.

An interface in the java.sql package that represents a set of precompiled SQL statements that can be executed multiple times with different values.

A class that provides the methods to interact with a database. It establishes a connection to the database and provides the means to execute SQL statements.

A class that encapsulates a connection to a database. It represents a communication channel between a Java application and a database.

An interface that represents a database-independent set of precompiled SQL statements. It provides a way to execute queries against a database.

Classes that provide a mechanism to handle events in Java programs. These classes represent objects that respond to actions from users or the system, such as a button click or a window closing.

A collection of related classes and interfaces that allow you to manage database connections, execute SQL statements, and retrieve data from a database.

A type of JDBC driver that connects to a database through a network protocol using a middleware server. This type of driver is considered more flexible and scalable.

A type of JDBC driver that is entirely written in Java and communicates directly with the database. This type offers high performance and portability.

A component that displays non-editable text on a window. It's simple, passive, and doesn't handle events. Usually used to present information to the user.
