Java 1.4: Cast primitive type to Object (Coupling vs Performance?) -

This is really related to a question I asked earlier, but I was hanged on this statement. I'm limited to Java 1.4 and I want to enter a int type in the object . Do I really need to use a integer class object or is there a way to put it directly (1.4 there is no auto-boxing). Is the price of this "manual boxing" suitable for importing a whole organs from three layers to 1 level, thus increasing coupling?

  There is no easy way to convert primitive to Java based on primitive object , But there is a slow pace and a faster way.  New integer (int)  is slow,  Integer.valueOf (int)  is fast. This is also true for all other types of types.  
 You do not need much code in Java 5 but internally, when you use Autoboxing for  valueOf ()  compiler.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!    






Git Bash script to check whether repo has any commits? -



    I have a script on which I need to work differently if there is one, which is one or more , Commits. What is the best way to do this?   Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
