Class AppletApiRemovalExamples

java.lang.Object

net.jrodolfo.java_evolution.java26.applet_api_removal.AppletApiRemovalExamples

public class AppletApiRemovalExamples
extends Object

Demonstrates removal of the Applet API in Java 26.

This example does not try to run an applet or restore browser-plugin-era tooling. Instead, it writes a tiny legacy source file that imports java.applet.Applet, compiles it with the current JDK, and captures the compiler failure. That makes the removal visible without depending on old browser integrations or obsolete platform modules.
