JAVA Multithreading Ticketing Problem __java

Define a class to implement the Runnable interface, define a ticketing method that needs to be synchronized, and then rewrite the Run method to call the ticketing sale method

Class Saleticket implements runnable{
	private int tickets =;
	
	
	Private synchronized void sale () {
		if (Tickets > 0) {
			System.out.println (Thread.CurrentThread (). GetName () + " Sell the first "+ (tickets--) +" Ticket ");
			
			try{
				Thread.Sleep (MB);
			catch (Interruptedexception e) {
				e.printstacktrace ();
	}}} public void Run () {while
		(Tickets > 0) {
			sale ();


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


		Saleticket st = new Saleticket ();
		thread T1 = new Thread (ST, "one Window");
		Thread t2 = new Thread (St, "No. second Window");
		thread t3 = new Thread (St, "No. third Window");
		thread T4 = new Thread (St, "No. Fourth Window");
		T1.start ();
		T2.start ();
		T3.start ();
		T4.start ();
		
	
		
	}
