My favorite quotations..
“A man should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.” by Robert A. Heinlein

To split a String into words (tokens) where delimiter is white space...
String delims = "[ ]+";
String[] tokens = someLongString.split(delims);
Now you can look thru the tokens and do comparisons, etc.

Function To Censor String
public String censorString(String originalString)
{
StringBuffer orig = new StringBuffer(originalString);
Pattern p = Pattern.compile("[0-9/A-Z/a-z]+");
Matcher m = p.matcher(orig);
StringBuffer censor = new StringBuffer();
boolean result = m.find();
while (result)
{
String match = originalString.substring(m.start(), m.end());
if(match.equals("badword"))
m.appendReplacement(censor, "[censored]");
result = m.find();
}
m.appendTail(censor);
return censor.toString();
}
Adding maven and SVN plugin to Eclipse 2.4.2
GWT Client Side Date / Calculate Age
Date today = new Date();
Integer currentYear = new Integer(DateTimeFormat.getFormat("yyyy").format(today));
Integer currentMonth = new Integer(DateTimeFormat.getFormat("M").format(today));
Integer currentDay = new Integer(DateTimeFormat.getFormat("d").format(today));
Age calculating function:
public static int calculateAge(Date dob)
{
Date today = new Date();
Integer currentYear = new Integer(DateTimeFormat.getFormat("yyyy").format(today));
Integer currentMonth = new Integer(DateTimeFormat.getFormat("M").format(today));
Integer currentDay = new Integer(DateTimeFormat.getFormat("d").format(today));
Integer dobYear = new Integer(DateTimeFormat.getFormat("yyyy").format(dob));
Integer dobMonth = new Integer(DateTimeFormat.getFormat("M").format(dob));
Integer dobDay = new Integer(DateTimeFormat.getFormat("d").format(dob));
int age = currentYear - dobYear;
if((dobMonth > currentMonth) || (currentMonth == dobMonth && dobDay > currentDay))
age--;
return age;
}
