Safely casting long to int in Java -

-

What is the most idiomatic method in Java to ensure that is long to int Do not lose any information?

This is my current implementation: 

  Public Static Int Safe Longtoint (long) {int i = (int) l; If ((long) I! = L) {Setting new invalid records exception (L + "can not be inserted without changing its value."); } Came back; A new method was added with

Java 8 To do this 

  import static java.lang.Math.toIntExact; Long afu = 10 l; Int bar = toIntExact (foo);

In case of overflow, an arithmetic will throw exceptions.

See:

Some other overflow safe methods have been added to Java 8. They end with exact .

Example:

  • Math.incrementExact (long)
  • math. SubtractExact (tall, long)
  • Math. TransitionXact (long)
  • Math AngateAccact (long),
  • Math. SubtractExact (int, int)

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session.

php - Laravel - Overriding a resource route into a different route filter group -

-
Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...
