bitwise operation on boolean

bitwise operation on boolean

The solution to the puzzle is given in the Java Language Specification, chapter 15.22.2:
15.22.2 Boolean Logical Operators &, ^, and |
When both operands of a &, ^, or | operator are of type boolean, then the type of the bitwise operator expression is boolean.
For &, the result value is true if both operand values are true; otherwise, the result is false.
For ^, the result value is true if the operand values are different; otherwise, the result is false.
For |, the result value is false if both operand values are false; otherwise, the result is true.

Someone mentioned that there is no boolean, byte and short in byte code level, all just integer

Improving performance in distributed Web applications

* Keep the session minimal - generally a bad idea to store shared objects in the session.
* Don't bypass setAttribute - if you just call getAttribute() to retrieve the Vector and then add something to it without then calling setAttribute again, the container might not realize that Vector has been changed.
* Use fine-grained session attributes - finer-grained objects in the session rather than one big monolithic object.
* Invalidate when done - call HttpSession.invalidate()
* Keep the session clean - remove reference to unuse thing to help GC

Optimizing HTTP downloads in Java through conditional GET and compressed streams

http://www.oreillynet.com/pub/wlg/5216

HTTP POST -

URL url = new URL(BASE_URL);
URLConnection con = url.openConnection();
// inform the connection that we will send output and accept input
con.setDoInput(true);
con.setDoOutput(true);

// Don't use a cached version of URL connection.
con.setUseCaches (false);
con.setDefaultUseCaches (false);
con.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
// define a new PrintWriter on the output stream
PrintWriter outWriter = new PrintWriter(con.getOutputStream());

// send data to the servlet
outWriter.print("htmlText="+inputHtml);
outWriter.close();

InputStream input = con.getInputStream();

Just come across a nice article that discuss about various new features of 1.5 and provide tips on how to use them: http://java.sys-con.com/read/171487_p.htm

Create collection quick

List programmingLanguages = CollectionUtils.newList("Java", "C++", "Ruby");

Or this:

Map langs = new HashMap(3) {{
put("Java", "Wicked");
put("C++", "Ok");
put("Ruby", "Interesting");
}};
