The isActive() method returns the current state of the applet. While an applet is initializing, it is not active, and calls to isActive() return false. The system marks the applet active just prior to calling start(); after this point, calls to isActive() return true.
The getDocumentBase() method returns the complete URL of the HTML file that loaded the applet. This method can be used with the getImage() or getAudioClip() methods to load an image or audio file relative to the HTML file.
The getCodeBase() method returns the complete URL of the .class file that contains the applet. This method can be used with the getImage() method or the getAudioClip() method to load an image or audio file relative to the .class file.
The getParameter() method allows you to get parameters from <PARAM> tags within the <APPLET> tag of the HTML file that loaded the applet. The name parameter of getParameter() must match the name string of the <PARAM> tag; name is case insensitive. The return value of getParameter() is the value associated with name; it is always a String regardless of the type of data in the tag. If name is not found within the <PARAM> tags of the <APPLET>, getParameter() returns null.
The getAppletContext() method returns the current AppletContext of the applet. This is part of the stub that is set by the system when setStub() is called.
The appletResize() method is called by the resize method of the Applet class. The method changes the size of the applet space to width x height. The browser must support changing the applet space; if it doesn't, the size remains unchanged.
