I am tracking the Java versions being used by web visitors: http://cowwoc.blogspot.com/2008/12/tracking-java-versions-using-google.html Unfortunately, the integration level is skin deep.

This has lead us to look for a good book focusing on the subject or another resource which explains how to set up a more redu...
How can I write a function that takes an array of integers and returns true if their exists a pair of numbers whose product is odd? What are the properties of odd integers? And of course, how do you write this function in Java? Also, maybe a short explanation of how you went about formulating an algorithm for the actual implementation. ...

I need to load a bunch of words (about 70,000) from a text file, add it to a hashtable (using soundex as a key) and sort the values. While doing all these I want to show a progress bar using JProgressBar. Articles such as this and this, only gives a non-real example (a while loop). Can anyone suggest me how should I proceed. How can I ge...

What is the best way to find the total number of words in a text file in Java? I'm thinking Perl is the best on finding things such as this. If this is true then calling a Perl function from within Java would be the best? What would you have done in condition such as this? Any better ideas? ...

I am trying to let a piece of runtime state decide WHICH implementation of an interface to use, preferably solely by autowiring. I have tried making an object factory for the interface thet uses dynamic proxies, and I used qualifiers to coerce the @Autowired injections to use the factory. The qualifiers are necessary because both the f...
