INTRODUCTION APPLETS Java applets are mini-programs that can be executed from a World Wide Web browser using special markup, when the browser loads a page that contains a

The jframe class is inherited from the jcomponent class.

In Java, each event is represented by an object that is a subclass of the EventObject class in the java.util package. Each subclass of EventObject represents a particular type of event. For example:

However, in the Java event model, EventObjects do not perform actions by themselves, but those events are sent to another object in charge of responding to a particular type of event. These objects are what we know as listeners, and there are different listeners that “listen” to different events, such as mouse listeners, key listeners or action listeners.

Listener are not implemented as classes in java, but as interfaces. An interface would then be a collection of methods that define a particular behavior. Thus, any class that provides information for such methods can declare that it implements such interface.

The JButton control is intended to allow the user to interact with it. The mechanics to catch the click of the JButton class object is done by implementing an ActionListener as we have just seen, plus the declaration of the method associated to that event, in this case actionPerformed.

The possibility of closing the application (EXIT_ON_CLOSE) by pressing the cross (x) in the upper right corner. In Linea01d.jav deploying “private void initComponents() {“, is a code that is generated by default.

b) It has an applet that gives a transparency effect so that the background of the screen or the application that we have open can be seen and also it is overprinted the result that we see in the picture that in fact is a clean background although it is observed a kind of box that is not explained how it is constructed and its utility.

In this application there are examples of how to draw lines, squares and how to round its vertices, other geometric figures (circle, oval, slope to find triangles, pentagons …), how to give thickness and color to its border, color its background and in awt mode and swing with NetBeans.

It is an Aplet. Curious example that leaves the transparent background, pending to see it with more detail in case of being a utility to use in some application. It also draws two very short thick lines and a text (word)

Document MetadataThe metadata contains information about the page. This includes information about styles, scripts and data that help software (search engines (en-US), browsers, etc.) to use and generate the page. Style and script metadata may be defined in the page or linked to another file that contains the information.

The HTML <base> element specifies the base URL to be used for all relative URLs contained within a document. There can be only one <base> element in a document.

The HTML <link> element specifies the relationship between the current document and an external resource. Possible uses of this element include defining a relational framework for navigation. This element is most often used to link style sheets.

Content sectioningContent sectioning elements allow you to organize the contents of the document into logical parts. Use the sectioning elements to create a broad description of the contents of your page, including the header and footer and elements to identify sections.
