Anonymous inner class implements thread creation __java

public class Main {public
	static void Main (string[] args) {for
		(int i=0;i<4;i++) {
			new Thread (New Runnable () {
				@Override public
				void Run () {
					for (int j=0;j<100;j++) {ticket.fun ()}}}
			, Window + (i+1)). Start ();}}

public class Ticket {
	static int a = 0;	
	Public synchronized static void Fun () {
		ticket.a++;
		System.out.println (Thread.CurrentThread (). GetName () + "is selling the first" +ticket.a+ "Ticket");
	}

The above code implements multiple threads to sell tickets at the same time, because A and fun () are shared resources, so with the lock, the thread must enter the lock that has to look at the thread to see if it is released or not. The new Runnable () {} above does not instantiate the Runnable interface, but instead instantiates an anonymous inner class that implements the Runnable interface, because it is anonymous, so you don't know what the name of the class is, if we write a class to implement the Runnable interface, Then we can replace the new Runnable () {} With this class that implements the Runnable interface, and of course the name class that implements the Runnable interface can write its own code in run (). If the class with the name implementation runnable and the anonymous inner class are written like run (), then the anonymous inner class will overwrite the class with the name.
