Lamda	Anonymous Class
On compilation, invokedynamic instruction is added to the class file.	On compilation, for each anonymous class, a separate class file gets generated. Example: DemoClass$1.class
Lamda expression and functional interface method are lately bound by invokedynamic insturction. Only the first call to a lambda expression is slow. Subsequent calls are faster.	Anonymous classes result in an additional class file being generated during compilation, which could increase the time required for class loading and verification during runtime.
"this" refers to enclosing class.	"this" refers to inner class.
