个人账户类:

public class PrivateAccount implements Callable {
    Integer total;
    
public Object call() throws Exception {
        Thread.sleep(
5*1000);
        total
=new Integer(new Random().nextInt(10000));
        System.out.println(
"您个人账户上还有"+total+" 存款可以支配");
        
return total;
    }
}

主函数测试:

public class SumTest {
    
/**
     * 
@param args
     * 
@throws ExecutionException 
     * 
@throws InterruptedException 
     
*/
    
public static void main(String[] args) throws InterruptedException, ExecutionException {
        Callable privateAccount
=new PrivateAccount();
        FutureTask task
=new FutureTask(privateAccount);
                
//创建新线程获取个人账户信息
        Thread thread=new Thread(task);
        thread.start();

        
int total=new Random().nextInt(1000);
        System.out.println(
"主线程在这工作");
        System.out.println(
"您目前操作金额为: "+total+" .");
        System.out.println(
"请等待计算个人账户的金额");
        
while(!task.isDone()){//判断是否已经获取返回值
            try {
                Thread.sleep(
3*1000);
            } 
catch (InterruptedException e) {
                
// TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        Integer privateSingle
=(Integer)task.get();
        
int post=privateSingle.intValue();
        
        System.out.println(
"您当前账户共有金额为:"+(total+post)+" ¥");
    }

}
