Java Thread Methods

Java Thread Creation

• A Java Thread can be created by subclassing the Thread class or by implementing the Runnable interface.
• A Thread subclass can be created by extending the Thread class and overriding the run() method.
• An anonymous subclass of Thread can be created using an anonymous class.
• A Runnable interface can be implemented using a Java class, an anonymous class, or a Java Lambda.

Thread Methods

• wait(): makes the thread wait until it gets a notification, releasing the lock prior to waiting and reacquiring the lock prior to returning.
• notify(): sends a notification to one of the waiting threads, waking it up and allowing it to execute the remaining task.
• notifyAll(): sends a notification to all the waiting threads, waking them up and allowing them to execute simultaneously.

Inter-Thread Communication

• wait(), notify(), and notifyAll() methods are used for inter-thread communication.

Java Swing

• Swing is a Java API for creating graphical user interfaces (GUIs).
• Swing offers advanced controls like Tree, TabbedPane, slider, colorpicker, and table controls.
• Swing controls can be easily customized, separating visual appearance from internal representation.
• The look and feel of Swing GUI applications can be changed during runtime, offering flexibility in appearance.

Swing Components

• JFrame is a class used to create and manage top-level windows in a Java GUI application.
• JButton is a class used to create a labeled button.

Java Swing Example

• A simple Swing example involves creating a button and adding it to a JFrame object.

Java Thread Methods

• join(): joins the start of a thread's execution to the end of another thread's execution, ensuring a thread does not start running until another thread ends.
• currentThread(): returns a reference to the currently executing thread object.

Creating Threads in Java

• Java provides a Thread class that can be extended to create custom threads.
• Java also provides a Runnable interface to define tasks for threads.

JSP vs JSF

• JSP (Java Server Pages) is a technology for generating HTML from Java code.
• JSF (JavaServer Faces) is a technology for creating reusable UI components.
• JSF provides a high-level, declarative approach to building web user interfaces.

Facelets

• Facelets is an XML-based view technology used in JSF to build User Interfaces in web applications.
• Facelets uses XHTML for creating web pages.
• Facelets supports XML namespace declarations to use different tag libraries to add components to a web page.
• XHTML is a markup language based on HTML that follows the XML syntax.
