Question

I’m using Sun’s javac 1.6.0_26. I invoke it like this:

javac -Xlint -encoding UTF-8 

and usually if there are errors only them are displayed. However this code

class Test{
    public static void main(String args[]) {
        java.util.Date d = new java.util.Date();
        system.out.println(d.getDate());
    }

produces both warning and error:

java:5: warning: [deprecation] getDate() in java.util.Date has been deprecated
        system.out.println(d.getDate());
                            ^
java:5: package system does not exist
        system.out.println(d.getDate());

So my question is: how do I make javac show only errors (without warnins) when there are any and all warnings when there are no errors (never both)?

Answer 1

There is a standard option in javac -nowarnwhich disable warning messages. You can get more informations from javac-options
