我正在进行一次技术测试,下面给出了问题陈述,我不知道我到底要做什么,请通过提供一些示例代码来帮助我.
Implement a hash-map data structure from scratch , where both key and value are of string data type.
The details of how a hash works can be found in Chapter 11 of the book "Introduction to
Algorithms" by Cormen, Leiserson, Rivest. You should also refer to Section 3.7 of "The
Algorithm Design Manual" by Steven Skiena. For the required hash-map implementation,
the following conditions hold true:
1. The key is made up of lower-case english alphabets only (a,b,c...z). It …我们使用软件应用程序将推文发布到来自同一IP地址的多个帐户.在twitter的回应中,我们得到403错误代码,我们使用的API是REST API.
是否对IP地址有任何限制,因为我们肯定没有跨越为REST API提到的API后限.
我们也不会超过140个字符.
等待回复..

class RunnableDemo implements Runnable
{
public void run()
{

{
try{}
catch(Exception e){ //exception caught}
}
}
}
如果捕获到异常,则线程被中断,但即使遇到异常,我也希望线程继续工作,所以请建议我一些方法来解决这个问题.
提前致谢
即使计算机进入睡眠模式,我也想保持我的应用程序运行.我在我的应用程序中使用了线程,它在特定的间隔后执行一些任务.
计算机睡眠时是否可以执行程序？
如果是,请提供一些解决方案或Java类.
