Some msg during compiling.. but program can be built... does it matters?

My program... when built thru netbeans ide, produces the following built output:

Note: Some input files use unchecked or unsafe operations.

Note: Recompile with -Xlint:unchecked for details.

To run this application from the command line without Ant, try:

java -jar "D:\TradingAlert\TradingAlert\dist\TradingAlert.jar"

jar:

BUILD SUCCESSFUL (total time: 12 seconds)

Can someone tell me what is "Note: Some input files use unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details."? Does it matters since my program can be build succesfully?

Thanks

Well you can do as the message says and use the -Xlint option to get details. In my experience I usually get that message when I have forgotten to include Generics when dealing with Collections.

new ArrayList();

new ArrayList<String>();

That's a warning, not an error, so it won't stop your program from compiling. It's just the compiler telling you that you're doing something that, while legal, looks fishy and might be a mistake or a poor approach.
