The Java Tutorials have been written for JDK 8. Examples and practices described in this page don't take advantage of improvements introduced in later releases and might use technology no longer available.
See Dev.java for updated tutorials taking advantage of the latest releases.
See Java Language Changes for a summary of updated language features in Java SE 9 and subsequent releases.
See JDK Release Notes for information about new features, enhancements, and removed or deprecated options for all JDK releases.
All browsers allow Java applets to display a short status string. All Java applets on the page, as well as the browser itself, share the same status line.
Never put crucial information in the status line. If many users might need the information, display that information within the applet area. If only a few, sophisticated users might need the information, consider sending the information to standard output (see Writing Diagnostics to Standard Output and Error Streams).
The status line is not usually very prominent, and it can be overwritten by other applets or by the browser. For these reasons, it is best used for incidental, transitory information. For example, an applet that loads several image files might display the name of the image file it is currently loading.
Applets display status lines with the
showStatus method, inherited in the JApplet class from the Applet class.
Here is an example of its use:
showStatus("MyApplet: Loading image file " + file);
