Once again, a late night Friday (Fri Aug 27 23:53:11 CDT 2010) Java quiz. This one arise out of work with Brian Coyner.

Q: Will the following Java program compile? Run without exceptions? If so, what does it print?

import java.util.Calendar; 
import java.util.Date; 
 
public class Main { 
    public static void main(String[] args) { 
        Date date = new Date(); 
        Date date2 = foo(date); 
        Date date3 = bar(date); 
        System.out.println("date2.getTime() == date3.getTime() = " + 
                (date2.getTime() == date3.getTime())); 
    } 
 
    private static Date foo(Date date) { 
        Calendar cal = Calendar.getInstance(); 
        cal.setTime(date); 
        cal.clear(Calendar.YEAR); 
        cal.clear(Calendar.MONTH); 
        cal.clear(Calendar.DATE); 
        cal.clear(Calendar.MILLISECOND); 
        return cal.getTime(); 
    } 
 
    private static Date bar(Date date) { 
        Calendar cal = Calendar.getInstance(); 
        cal.setTime(date); 
        Calendar cal2 = Calendar.getInstance(); 
        cal2.clear(); 
        cal2.set(Calendar.HOUR_OF_DAY, cal.get(Calendar.HOUR_OF_DAY)); 
        cal2.set(Calendar.MINUTE, cal.get(Calendar.MINUTE)); 
        cal2.set(Calendar.SECOND, cal.get(Calendar.SECOND)); 
        return cal2.getTime(); 
    } 
}

Oh boy! Is this real?

San Francisco Chronicle:

(08-12) 17:17 PDT Redwood Shores, Calif. (AP) --

Oracle Corp. said Thursday it has filed a patent and copyright-infringement lawsuit against Google Inc.

Oracle said in a statement that Google's Android system for mobile phones infringes on its patented Java technology.

This is the other shoe dropping in a story I reported 1221 days ago:

• Java: The Third Fork From Sun

Here's an excerpt of a couple of comments from that post:

Is this the end of Java as we know it?

... IOC container.

Bill Burke (commenting on TheServerSide.com): Currently plain Java is my favorite IoC container. Nothing beats the simplicity of constructor and getter/setter methods. I'm so sick of seeing the guts of applications exposed through ugly XML or writing a billion annotations just to get access to a simple component. Its all ridiculous, bloated, and most of the time unnecessary. Anybody else fed up?

I know a lot of people who has sentiments like Bill's. I can just hear them say:

• My favorite OR mapping tool is JDBC
• My favorite quote-and-quote application server is the Java process
• My favorite logging solution is java.logging API
• My favorite application modeling tool are Java interfaces
• My favorite web application framework is none of the usual candidates
• My favorite JVM language is Java

And, yes, Bill, we are all fed up with writing stupid XML files!
