String, text, numbers, I/O II part

character and call charWidth(char ch) on each. It should return the same value for

 Q: I want to create a Date object by just specifying the Year, Month and Day.

e.g. the user can enter 1998 as Year, 11 as Month of Nov, 15 as the day.

With these three information, how can i create a Date object (or similar object that

stores the data)?

Answer: The correct way to do this is something like this:

Calendar cal = Calendar.getInstance();

cal.set(1998, Calendar.NOVEMBER, 15);

Date date = cal.getTime();

 Q: I want to send Image through network. I made OutputStream to send Image...

OutputStream out = socket.getOutputStream();

but I can t send Image directly.

How can I send Image?

Answer: Unfortunately, the java.awt.Image class is abstract and is not serializable,

otherwise this would be easy.

From the Java docs: "The abstract class Image is the superclass of all classes that

represent graphical images. The image must be obtained in a platform specific

manner."

Consider using the Image.getSource method, getting the producer, getting the bytes,

then send [width][height][bytes...].

 Q: I want to get the code behind an HTML page.

For example: I lock on www.sun.com and then get the source code behind the page

(what you see :right mouse click "source code" for window users) and put it in a file

or something like that....

I am particularly interested in retrieving the code of html

I thought to do it with getContent() or with bufferStreamReader() something like that..
