Figure 1.3 The steps to create a Java applet and a web page to hold it. Loading the
web page in a browser or running it with the appletviewer program will display the
applet as shown in Figure 1.4.
1.8.3 First applet
Figure 1.3 shows the steps to create an applet. The following applet code displays
