Foreword through Jeff Friesen.
Beginning Java eight APIs, Extensions and Libraries completes the Apress Java studying trip and is a entire method of studying the Java Swing, JavaFX, Java Scripting, JDBC and community programming APIs.
This ebook covers the main extesnsions of the Java programming language reminiscent of Swing, JavaFX, community programming, and JDBC. every one subject begins with a dialogue of the topic's heritage. A step by step procedure, with small snippets of Java code, presents easy-to-follow directions. on the finish of an issue, an entire and ready-to-run Java application is supplied. This e-book comprises over a hundred thirty photos and diagrams that will help you visualize and higher comprehend the themes. greater than a hundred thirty whole courses let you perform and quick examine the topics.
The Swing chapters speak about a number of points of operating with a GUI, from the very uncomplicated techniques of constructing a Swing program, to the main complex themes, reminiscent of adorning a Swing part with a JLayer, drag-and-drop positive factors, Synth Skinnable L&F, etc.
The bankruptcy on community programming covers the fundamentals of community applied sciences first, after which, the complicated issues of community programming, utilizing a Java type library. It covers IPv4 and IPv6, addressing schemes, subnetting, supernetting, multicasting, TCP/IP sockets, UPD sockets, asynchronous socket I/O, etc.
The bankruptcy on JDBC offers the main points of connecting and dealing with databases reminiscent of Oracle, SQL Server, MySQL, DB2, Java DB (Apache Derby), Sybase, Adaptive Server anyplace, and so on. It encompasses a entire dialogue on processing a ResultSet and a RowSet. It discusses the way to use the RowSetFactory, to acquire a RowSet item of a selected style. operating with huge gadgets (LOBs), akin to Blob, Clob, and NClob, is roofed intimately with Java code examples and database scripts.

The constraints of a component are used to lay out the component. Some of the constraints include the component’s position in the grid, width, height, alignment inside the cell, etc. setLayout(gridBagLayout); Let’s use GridBagLayout in the simplest form: create a frame, set the layout for its content pane to GridBagLayout, and add nine buttons to the content pane. This is accomplished in Listing 1-14. Figure 1-26 shows the screen you get when you run the program. Listing 1-14. setVisible(true); } } Figure 1-26.
WEST It is synonymous with x. It is the left edge of the component. SOUTH It is the bottom edge of the component. Its value is the same as NORTH + HEIGHT. EAST It is the right edge of the component. It is the same as WEST + WIDTH. WIDTH The width of the component. HEIGHT The height of the component. HORIZONTAL_CENTER It is the horizontal center of the component. It is the same as WEST + WIDTH/2. VERTICAL_CENTER It is the vertical center of the component. It is the same as NORTH + HEIGHT/2. BASELINE It is the baseline of the component.
I have not discussed how to add an action listener to a button yet. It is necessary to see the CardLayout in action. I will discuss how to add an action to a button in detail in the event handling section. For now, it is sufficient to mention that you need to call the addActionListener() method of the JButton class to add an action listener to it. This method accepts an object of type ActionListener interface and has one method called actionPerformed(). The code in the actionPerformed() method is executed when you click the JButton.
