问题原因其实很简单,就是没有对这个数组进行初始化操作,即当前只存在数组的声明,系统只为二维数组对象的引用变量分配了空间,并没有创建相应的数组对象 。那么在相关的方法中,自然无法对这个看似存在但实际却找不到影儿的数组进行操作,所以就会报错了。 解决办法 在类中再添加一个成员方法init(),给这个对象数组进行内...
and cloud computing services. moreover, it enhances the performance of gaming engines and real-time systems, such as those used in financial trading and autonomous vehicles, by allowing multiple operations to run in parallel, thereby improving processing speed and responsiveness. what challenges are ...
Java synchronization works on locking and unlocking of the resource before any thread enters into synchronized code, it has to acquire the lock on the Object and when code execution ends, it unlocks the resource that can be locked by other threads. In the meantime, other threads are in wait ...
Whent1enters this method, it is kept in an infinite while loop; this is just to imitate heavy processing so that all other threads cannot enter this method Now when we startt2, it tries to enter thecommonResource()method, which is already being accessed byt1,thus,t2will be kept in theB...

文档中心也提供了如何移植RT-Thread Nano的笔记,但笔记归笔记,毕竟要自己动手去做才能了解这个过程,方便以后分析调试。 2、移植RT-Thread Nano到小熊派 2.1 在官网上下载RT-Thread Nano 解压后得到如下文件: 2.2 使用stm32CubeMX生成一个基础工程 由于之前已经写了很多CubeMX配置的文章,所以这里不详细写了,只写我配...
executor.execute(worker); } executor.shutdown(); while (!executor.isTerminated()) { } System.out.println("Finished all threads"); } } In the above program, we are creating a fixed-size thread pool of 5 worker threads. Then we are submitting 10 jobs to this pool, since the pool si...
