select 1 from dual 占用cpu高
当你执行 `select 1 from dual` 这个语句时，实际上并不会占用高CPU。这个查询语句非常简单，只返回一个固定的结果，不会造成CPU负载的明显增加。 如果你观察到CPU使用率升高，可能是其他原因导致的。可以考虑检查其他正在运行的进程、查询是否有其他复杂的操作导致了高CPU负载。还可以使用性能分析工具来查看系统的资源使用情况和性能瓶颈。 [2024-01-17 18:01:38 | AI写代码神器 | 180点数解答]

- 1、用类描述计算机CPU的速度和硬件的容量。要求java应用程序有4个类，名字分别是PC、CPU、Hardisk、 和Test,其中Test是主类。 2、 其中，CPU类要求getSpeed()返回speed值，要求setSpeed(int m)方法将参数m的值赋值给speed；HardDisk类要求 getAmount()返回amount的值，要求setAmount(int m)方法将参数m赋值给amount;PC类要求setCPU(CPU c)将参数c的值赋值给cpu，要求setHardDisk(HardDisk h)方法将参数h的值赋值给HD，要求show()方法能显示cpu的速度和硬盘容量。 3.主类的要求 (1)main方法中创建一个CPU对象cpu，cpu将自己的speed设置为2200。 (2)main方法中创建一个HardDisk对象disk，disk将自己的amount设置为200。 (3)main方法中创建一个PC对象pc。 (4)pc调用setCPU(CPU c)方法，调用时实参时cpu。 ( 5)pc调用setHardDisk(HardDis（441点数解答 | 2025-04-15 16:14:52）123
