Anonymous inner class

/* Anonymous inner class: A class without a class name is called an anonymous inner class. The benefits of anonymous inner classes: simplify writing. The use of anonymous inner classes is premised on the existence of an inheritance or implementation relationship before it can be used. Anonymous inner classes are generally used for arguments. */abstract class Animal{public abstract Animal run ();p ublic abstract void Sleep ();} Class outer{public void print () {//requirement: Define a class within the method to inherit the animal class, and then call the Run method with sleep (). /*//local inner class dog extends animal{public void run () {System.out.println ("dog running..");} public void Sleep () {System.out.println ("dog lying in Open eyes sleeping.");}} Create object Dog d = new Dog ();d.
