The Java Developers Almanac 1.4

I find this site today, well I found it because it was one of the Java Series books that Sun promotes but this one had a website, which means I can see the goodies for free.

it is similar in some ways to Java Tips, which I have blogged about http://hoskinator.blogspot.com/2006/04/java-tips.html
except that this site is purely just code examples where as Java tips does have explanations as well.

The code examples are split up into packages but it does have a useful search facility where you can search for the code example you are interested in. The obvious down fall is the code examples are for 1.4 and not 1.5 and it hasn't been updated for quite a while.

It gives you just a short concise example of the code you are interested in, I always like seeing an example and then changing and modifying it to do want I want, it always seems a good starting point e.g. you have something that works and then you change

If anyone has any other code example site's like this I would like to hear about them and mention them in the comments if you would be so kind.

it has some good sections on java.sql, java.text and java.reflect and lots more

a few examples of the type of things featured on the site

e332. Breaking a String into Words
e338. Comparing Arrays
e340. Converting a Collection to an Array
e365. Reading and Writing a Properties File
e320. Formatting a Date Using a Custom Format
below is the entry for Formatting a Date using a Custom Format
e316. Formatting the Time Using a Custom Format

A pattern of special characters is used to specify the format of the time. This example demonstrates some of the characters. For a complete listing, see the javadoc documentation for the SimpleDateFormat class.

Note: This example formats dates using the default locale (which, in the author's case, is Locale.ENGLISH). If the example is run in a different locale, the text (e.g., month names) will not be the same.

Format formatter;

// The hour (1-12)
formatter = new SimpleDateFormat("h"); // 8
formatter = new SimpleDateFormat("hh"); // 08

// The hour (0-23)
formatter = new SimpleDateFormat("H"); // 8
formatter = new SimpleDateFormat("HH"); // 08

// The minutes
formatter = new SimpleDateFormat("m"); // 7
formatter = new SimpleDateFormat("mm"); // 07

// The seconds
formatter = new SimpleDateFormat("s"); // 3
formatter = new SimpleDateFormat("ss"); // 03

// The am/pm marker
formatter = new SimpleDateFormat("a"); // AM

// The time zone
formatter = new SimpleDateFormat("z"); // PST
formatter = new SimpleDateFormat("zzzz"); // Pacific Standard Time
formatter = new SimpleDateFormat("Z"); // -0800

// Get today's date
Date date = new Date();

// Some examples
formatter = new SimpleDateFormat("hh:mm:ss a");
String s = formatter.format(date);
// 01:12:53 AM

formatter = new SimpleDateFormat("HH.mm.ss");
s = formatter.format(date);
// 14.36.33
