Android 多執行緒

1，常用的thread 和running的方法 

public static void thread()

});thread.start();
}private static void running()
};thread thread = new thread(runnable);
thread.start();
}private static void threadfactory()
};runnable runnable = new runnable() 
};thread thread1 = threadfactory.newthread(runnable);
thread thread2 = threadfactory.newthread(runnable);
thread1.start();
thread2.start();
}

private static void executor()

};executor executor = executors.newcachedthreadpool();
executor.execute(runnable);
executor.execute(runnable);
executor.execute(runnable);
}

// 自定義共用執行緒池

blockingdequequeue = new linkedblockingdeque<>(10000);
executor threadpool = new threadpoolexecutor(5,100,5l, timeunit.seconds,queue);

// 又返回值的後台

static void callable()
};executorservice executor = executors.newcachedthreadpool();
futurefuture = executor.submit(callable);
try catch (interruptedexception e) catch (executionexception e) 
}

synchronized  volatile lock atomicinteger(自增)

reentrantreadwritelock(讀寫鎖)：讀的時候，other可以讀，但不可以寫；寫的時候，other讀和寫都不可以
