package executor;

import java.util.concurrent.Callable;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

public class ExecutorTest {

    public static void main(String[] args) {
        methodB();
    }
    
    static void methodB(){
        ExecutorService newSingleThreadExecutor = Executors.newSingleThreadExecutor();
        Future<String> submit = newSingleThreadExecutor.submit(new Callable<String>() {

            @Override
            public String call() throws Exception {
                // TODO Auto-generated method stub
                return "success";
            }
        });
        try {
            System.out.println(submit.get());
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (ExecutionException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    public  static void methodA(){
        ExecutorService newCachedThreadPool = Executors.newCachedThreadPool();
        for(int i=0;i<5;i++){
            newCachedThreadPool.execute(new Runnable() {
                
                @Override
                public void run() {
                    // TODO Auto-generated method stub
                    System.out.println("test");
                }
            });
        }

        while(!newCachedThreadPool.isTerminated()){
            System.out.println(""+newCachedThreadPool);
        }
    }
}
