基于Java Callable接口实现线程代码实例

import java.util.concurrent.Callable;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.FutureTask;

public class Test_13 {
  public static void main(String[] args) {
    System.out.println(Thread.currentThread().getName() + "begin");
    FutureTask task = new FutureTask(new Callable() {
      @Override
      public Object call() throws Exception {
        System.out.println(Thread.currentThread().getName() + "start");
        Thread.sleep(1000 * 5);
        int a = 100;
        int b = 200;
        System.out.println(Thread.currentThread().getName() + "over");
        return a + b;
      }
    });
    Thread thread = new Thread(task);
    thread.start();
    try {
      System.out.println(task.get());
    } catch (InterruptedException e) {
      e.printStackTrace();
    } catch (ExecutionException e) {
      e.printStackTrace();
    }
    System.out.println(Thread.currentThread().getName() + "end");
  }
}
