"Java" "Anonymous inner class"

/*
Anonymous inner class
is the simplified notation of the inner class.

Premise: There is a class or interface
The class here can be either a concrete class or an abstract class.

Format:
New class name or interface name () {
Override method;
}

What is the essence of it?
is an anonymous object that inherits the class or implements the interface's subclass.
*/

Interface Study
Interface Study {
public abstract void Read ();

public abstract void Write ();
}

Abstract class Play
Abstract class Play {
public abstract void Kongfu ();
}

Hulk Implementation Interface Study
Class Hulk implements Study {
public void Read () {
System.out.println ("I can read");
}

public void Write () {
System.out.println ("I can write");
}

}

Pander inheriting abstract class play
Class Pander extends play{
public void Kongfu () {
System.out.println ("I love Kongfu");
}
}

public class Anonymousinnerclass {
public static void Main (string[] args) {

Method One: Do not use anonymous inner classes
If you use it only once, creating an inherited class and implementing a class is a waste of memory, so the anonymous inner class applies only once.
Study s = new Hulk ();
S.read ();
S.write ();

Play p = new pander ();
P.kongfu ();
System.out.println ("------------\ n");

Method Two: Use anonymous inner classes
New Study () {
public void Read () {
System.out.println ("I can read");
}

public void Write () {
System.out.println ("I can write");
}
}.read ();

New Study () {
public void Read () {
System.out.println ("I can read");
}

public void Write () {
System.out.println ("I can write");
}
}.write ();

New Play () {
public void Kongfu () {
System.out.println ("I love Kongfu");
}
}.kongfu ();

System.out.println ("------------\ n");

Method Three: Another way to simplify the anonymous inner class

Study ss= New Study () {
public void Read () {
System.out.println ("I can read");
}

public void Write () {
System.out.println ("I can write");
}
};

Ss.read ();
Ss.write ();

Play pp =new play () {
public void Kongfu () {
System.out.println ("I love Kongfu");
}
};
Pp.kongfu ();

}

}
