Applet Tag || Java Applets || Java Tutorial for beginners

The HTML APPLET Tag
• The syntax for a fuller form of the APPLET tag is shown here. Bracketed items are optional.

APPLET
[CODEBASE = codebaseURL]
CODE = appletFile
[ALT = alternateText]
[NAME = appletInstanceName]
WIDTH = pixels HEIGHT = pixels
[ALIGN = alignment]
[VSPACE = pixels] [HSPACE = pixels]

[PARAM NAME = AttributeName VALUE = AttributeValue]
[ PARAM NAME = AttributeName2 VALUE = AttributeValue]

• CODEBASE [CODEBASE = codebaseURL]
o CODEBASE is an optional attribute that specifies the base URL of the applet code, which is the directory that will be searched for the applet’s executable class file

• CODE CODE = appletFile
o CODE is a required attribute that gives the name of the file containing your applet’s compiled .class file.
• ALT
o The ALT tag is an optional attribute used to specify a short text message that should be displayed if the browser recognizes the APPLET tag but can’t currently run Java applets.

• NAME
o NAME is an optional attribute used to specify a name for the applet instance.
o Applets must be named in order for other applets on the same page to find them by name and communicate with them.

• WIDTH and HEIGHT
o WIDTH and HEIGHT are required attributes that give the size (in pixels) of the applet display area.

• ALIGN
o ALIGN is an optional attribute that specifies the alignment of the applet. This attribute is treated the same as the HTML IMG tag with these possible values: LEFT, RIGHT, TOP, BOTTOM, MIDDLE, BASELINE, TEXTTOP, ABSMIDDLE, and ABSBOTTOM.

• VSPACE and HSPACE
o These attributes are optional. VSPACE specifies the space, in pixels, above and below the applet. HSPACE specifies the space, in pixels, on each side of the applet.

• PARAM NAME and VALUE
o The PARAM tag allows you to specify applet-specific arguments in an HTML page. Applets access their attributes with the getParameter( ) method.
