Building an Applet

To build an applet, you need to have the SDK installed. After that's done, you'll follow a four-step process.

To build a Java application:

1. Enter the code into a text file.

2. Compile all classes by using javac.

3. Write an HTML file that loads the applet.

4. Load the HTML file by using your Web browser.

This section covers the first two steps. The next section, "Running the Applet," describes the last two steps.
