Use the Object getClass() method to get a Class object
Every class has the class Object as an ancestor. A reflection method in the Object class is getClass(), which returns the Class of that object.

I/O Event Handling
The I/O architecture of our router was strongly inspired by the Swing event-dispatch model. In Swing, events generated by the user interface are received by the JVM and stored in an even
Smokescreen Introduction
Smokescreen is a Java obfuscator. Aside from being able to change symbolic names, it can also modify the bytecode instructions in methods thereby obfuscating control flow. This makes the resulting obfuscated classes much more difficult to decompile.
Dynamic Delegation and Its Applications

Internals of Java Class Loading
When are two classes not the same? When they're loaded by different class loaders. This is just one of many curious side effects of Java's class-loading system. Binildas Christudas shows how different class loaders relate to one another and how (and why)
