Because it’s a waste product, I won't advise swimming in it.

These restrictions piss me off. If I had my way, I would not allow non smokers to sit in the smoking zone.

Is it practical to have a smoking zone in a bar? As Darryl pointed out earlier...

Having a smoking section in a restaurant is like having a peeing section in a swimming pool.

Is that reasonable?

Just as the law protects the innocent from criminals, it also protects non-smokers from smokers. One of the problems with smoking is that it contains a cocktail of toxic chemicals; many of which find their way into the bloodstream and contribute to plaque buildup in the arteries. People should not be allowed to spread this poison.

Living in tents is not the African Standard. Living a "pre-colonial" lifestyle is not the African Standard.

That's a pretty ignorant statement. How much do you know about African Standards?

You can compile and run a class in a default package (just like any other class). The only problem is that you cannot import the default package.

You may need to set a classpath when invoking the javac command if the .java file you're trying to compile, uses a compiled class. One of the options to the javac command is -classpath. Read more here.

A data-center UPS might be appropriate in your case

If your needs are not simple, you could just buy one really good one. These machines range from cheap ones which can support only a single equipment, to expensive ones which can support multiple equipments.

Alternatively, you can buy UPS (uninterruptible power supply) off ebay. Some sell for as low as $20.

Take a look at this.

class B can access a protected member declared in class A (located in a different package), only through inheritance i.e. only through a reference which is of type B (or a subclass of B).

class C can access a protected member declared in class A (located in a different package), only through inheritance i.e. only through a reference which is of type C (or a subclass of C).

I don't know what your main method looks like, but if you use this main method and you save file.gif in the src folder, you will see the image.

public static void main(String args[]) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel pic = new JPanel(); ImageIcon pc = new ImageIcon("src/file.gif"); JLabel lab = new JLabel(pc, SwingConstants.CENTER); pic.add(lab); frame.add(pic); frame.setSize(800, 800); frame.setVisible(true); }

The statement Dozens[] da = new Dozens[3] creates the first object i.e. a Dozens array (1). The statement da[0] = new Dozens() creates 2 objects i.e. a Dozens object (2) and an int array (3). The statement Dozens d = new Dozens() creates 2 objects i.e. a Dozens object (4) and an int array (5). Total objects created is 5.

The statements d = null and da[1] = null make objects (4) and (5) eligible for GC at line 14. Both statements are necessary or else objects (4) and (5) wont be eligible for GC at line 14.

public class Dozens { int[] dz = {1,2,3,4,5}; //one int array object } class Eggs{ public static void main(String[] args){ Dozens[] da = new Dozens[3]; //two array object da[0] = new Dozens(); //third object Dozens d = new Dozens(); //fourth object not connected to array "da" da[1] = d; // <== is this a new "d" ( i mean a copy? ) // i think its the fifth one d = null; //one gc da[1] = null; //two gc // do stuff } }
