[SOLVED] An annoying warning everytime I compile
Everytime I compile a file I get this warning:
Note: C:\Documents and Settings\<user name>\Desktop\Multiple Desktops\DesktopArray.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
Process completed.
The file performs some basic file creation and movement in a folder in the C drive. If the code is needed I could provide it. I was wondering if there is a way I could stop this message from displaying every time I compile. I use JCreator if that matters at all... |

Seems this warning related to your application. Did you get this warning for simple applications, just like printing a message?

ive had this. basicly if you have any sort of Collection. like a ArrayList, HashSet ect you have to tell the compiler what Type of variables are going to be in it. for example
ArrayList list = new ArrayList(); will give u that warning
ArrayList<String> list = new ArrayList<String>(); will get rid of the warning because you told the compiler that your going to put strings in it. just change it to Integers or Objects or whatever your going to put in it.

Interesting, Netbeans or Eclipse doesn't give this warning at all. Typically ArrayList can hold any primitive data type, no need to specified. What Java version you guys use?

I used 1.6.0_05 with Netbeans. So there is a bit different(actually improvement) in exceptions. Because I don't get such warnings in my applications.

Use the same version and not for me. I don't think IDE effect for this. JDK version is the case.
